[0003]
For example, in the case of this mini-disc system, in order to manage the area where the user recorded on the disk (data recorded area) and the area where nothing has been recorded yet (data unrecorded area), Apart from main data such as music, management information called user TOC (hereinafter referred to as U-TOC) is recorded. The recording device discriminates an area for recording while referring to the U-TOC, and the reproducing device discriminates an area to be reproduced with reference to the U-TOC.
[0004]
That is, in the U-TOC, each recorded music or the like is managed in a data unit called a track, and its start address, end address, etc. are recorded. As for a free area where nothing is recorded, its start address, end address, etc. are recorded as areas that can be used for future data recording.
[0005]
Further, in such a mini-disc system, a user can use a predetermined operation method for a disc name that can indicate a disc title and the like, and a track name that can indicate a title of a song or the like recorded in units of tracks (programs). It is possible to enter and register according to. In the mini-disc system, such character information registered as a disc name and track name is also stored in a predetermined area on the U-TOC. For example, during playback, it is stored in the U-TOC as necessary. The displayed disc name and the track name of the desired track can be displayed and output.
Users can use these functions to register names for discs and tracks. For example, after that, the name of the disc loaded in the playback device and the track number for each track are displayed on the display. can do.
[0006]
[Problems to be solved by the invention]
By the way, when the user inputs the disk name or the track name (hereinafter referred to as “name” when both are collectively), for example, the name to be input has been input in the past. If the name is the same or part of the name, or is close to the name, there is a natural desire to copy and use a name that you have entered in the past as the name you are about to enter. It is.
However, the conventional name input method does not have the name copy function as described above, and the user has to perform the troublesome operation of inputting each character from the first character forming the name unit for each disk name or track name. It was forced.
[0007]
[Means for Solving the Problems]
In consideration of the above-described problems, an object of the present invention is to make it possible to copy a name when inputting a name, thereby improving the usability of a user.

In the present embodiment, these operation means are arranged on the front panel of the recording / reproducing apparatus for the sake of explanation. For example, the recording / reproducing apparatus can be operated by a remote commander using infrared rays or the like. Operation means may be provided.
[0021]
The internal configuration of the mini-disc recording / reproducing apparatus as shown in FIG. 1 will be described with reference to FIG.
A magneto-optical disk 1 on which audio data is recorded is driven to rotate by a spindle motor 2. The magneto-optical disk 1 is irradiated with laser light from the optical head 3 during recording / reproduction.
[0022]
The optical head 3 performs high-level laser output for heating the recording track to the Curie temperature during recording, and relatively low-level laser output for detecting data from reflected light by the magnetic Kerr effect during reproduction. .
For this reason, the optical head 3 is equipped with a laser diode as laser output means, an optical system including a polarizing beam splitter, an objective lens, and the like, and a detector for detecting reflected light. The objective lens 3a is held by a biaxial mechanism 4 so as to be displaceable in the radial direction of the disc and in the direction in which the objective lens 3a is in contact with or separated from the disc.
[0023]
Further, a magnetic head 6a is disposed at a position facing the optical head 3 with the disk 1 interposed therebetween. The magnetic head 6a performs an operation of applying a magnetic field modulated by the supplied data to the magneto-optical disk 1.
The entire optical head 3 and the magnetic head 6 a can be moved in the radial direction of the disk by the thread mechanism 5.
[0024]
Information detected from the disk 1 by the optical head 3 by the reproducing operation is supplied to the RF amplifier 7. The RF amplifier 7 performs processing of the supplied information to reproduce RF signal, tracking error signal TE, focus error signal FE, and groove information (absolute position information recorded as a pregroove (wobbling groove) on the magneto-optical disk 1). Extract GFM and the like.
The extracted reproduction RF signal is supplied to the encoder / decoder unit 8. The tracking error signal TE and the focus error signal FE are supplied to the servo circuit 9, and the groove information GFM is supplied to the address decoder 10.
[0025]
The servo circuit 9 receives various servo drive signals based on the supplied tracking error signal TE, focus error signal FE, track jump command, access command, spindle motor 2 rotational speed detection information, etc. from a system controller 11 constituted by a microcomputer. The biaxial mechanism 4 and the sled mechanism 5 are controlled to perform focus and tracking control, and the spindle motor 2 is controlled to a constant linear velocity (CLV).
[0026]
The address decoder 10 extracts address information by decoding the supplied groove information GFM. This address information is supplied to the system controller 11 and used for various control operations.
The playback RF signal is subjected to decoding processing such as EFM demodulation and CIRC in the encoder / decoder unit 8. At this time, an address, subcode data, and the like are also extracted and supplied to the system controller 11.
[0027]
The audio data (sector data) decoded by the encoder / decoder 8 such as EFM demodulation and CIRC is temporarily written into the buffer memory 13 by the memory controller 12. The reading of data from the disk 1 by the optical head 3 and the transfer of reproduction data in the system from the optical head 3 to the buffer memory 13 are performed at 1.41 Mbit / sec and are usually performed intermittently.
[0028]
The data written in the buffer memory 13 is read at a timing when the reproduction data transfer is 0.3 Mbit / sec and is supplied to the encoder / decoder unit 14. Then, reproduction signal processing such as decoding processing for audio compression processing is performed, and 44.1 KH._Z The digital audio signal is sampled and 16-bit quantized. This digital audio signal is subjected to adjustment processing such as equalizing, reverberation and gain in the digital signal processing circuit 21, for example, and then converted into an analog signal by the D / A converter 15 and supplied from the output terminal 16 to a predetermined amplification circuit unit. And played back. For example, it is output as an L, R analog audio signal.
[0029]
The digital signal processing circuit is formed by a so-called DSP (digital signal processor) or the like, and can perform various types of processing. For example, not only equalizing processing with acoustic settings in various modes but also processing such as fade-in and fade-out by gradually changing the gain (output volume level) is possible.
Such a processing unit may be provided in the subsequent stage of the D / A converter 15 and may be performed by analog processing.
[0030]
When a recording operation is performed on the magneto-optical disk 1, the recording signal (analog audio signal) supplied to the input terminal 17 is converted into digital data by the A / D converter 18, and then the encoder / decoder. Is supplied to the unit 14 and is subjected to audio compression encoding processing.
Although not shown, it is of course possible to provide a digital interface unit to input / output digital audio data.
[0031]
The recording data compressed by the encoder / decoder unit 14 is once written in the buffer memory 13 by the memory controller 12, read at a predetermined timing, and sent to the encoder / decoder unit 8. The encoder / decoder 8 performs encoding processing such as CIRC encoding and EFM modulation, and then supplies the magnetic head driving circuit 6 with the encoding processing.
[0032]
The magnetic head drive circuit 6 supplies a magnetic head drive signal to the magnetic head 6a in accordance with the encoded recording data. That is, an N or S magnetic field is applied to the magneto-optical disk 1 by the magnetic head 6a. At this time, the system controller 11 supplies a control signal to the optical head so as to output a recording level laser beam.
[0033]
The operation unit 19 indicates a part used for user operation, which corresponds to various operation keys and dials as described in FIG. Operation information by these operation keys and dials is supplied to the system controller 11, and the system controller 11 executes operation control according to the operation information.
The display unit 20 is provided on the housing as shown in FIG. 1, and this display operation is controlled by the system controller 11.
[0034]
The system controller 11 is a microcomputer including a CPU, a program ROM, a work RAM, an interface unit, and the like, but the illustrated work RAM 11a is designated as a copy source in the name copy mode of the present embodiment. It can be used to temporarily store character information data. The character information data as the copy source may be temporarily stored in a predetermined area of the buffer memory 13.
[0035]
By the way, when recording / reproducing operation is performed on the disc 1, it is necessary to read management information recorded on the disc 1, that is, P-TOC (pre-mastered TOC) and U-TOC (user TOC). The system controller 11 determines the address of the area to be recorded on the disc 1 and the address of the area to be reproduced according to the management information.
This management information is held in the buffer memory 13.
Then, the system controller 11 reads out the management information by executing the reproducing operation on the innermost circumference side of the disc on which the management information is recorded when the disc 1 is loaded, and stores it in the buffer memory 13. Thereafter, it can be referred to during recording / reproducing / editing operations on the disc 1.
[0036]
The U-TOC is rewritten according to data recording and various editing processes. However, the system controller 11 performs U-TOC update processing stored in the buffer memory 13 each time recording / editing operations are performed. The TOC information is performed, and the U-TOC area of the disc 1 is also rewritten at a predetermined timing according to the rewriting operation.
[0037]
<2. Cluster format>
Here, a unit called cluster will be described.
FIG. 3 shows a cluster format as a recording operation unit in the mini-disc system.
As shown in FIG. 3, clusters CL are continuously formed as recording tracks in the mini disk system, and one cluster is set as a minimum unit during recording. One cluster corresponds to two to three rounds of tracks.
[0038]
And one cluster CL is sector S_FC~ S_FF4 sectors linking area and sector S₀₀~ S_1FAre formed from a 32-sector main data area.
One sector is a data unit formed of 2352 bytes.
Sector S_FC~ S_FFThese four sectors are used as sub-data recording and linking areas, and TOC data, audio data, etc. are recorded in a 32-sector main data area.
The address is recorded for each sector.
[0039]
The sectors are further divided into units called sound groups, and two sectors are divided into 11 sound groups.
That is, as shown, sector S₀₀Even sectors such as Sector S₀₁Sound group SG in two consecutive sectors of odd sectors such as₀₀~ SG_0AIs included. One sound group is formed of 424 bytes, and has an audio data amount corresponding to a time of 11.61 msec.
In one sound group SG, data is recorded divided into an L channel and an R channel. Sound group SG₀₀Is composed of L channel data L0 and R channel data R0, and the sound group SG₀₁Consists of L channel data L1 and R channel data R1.
Note that 212 bytes, which are the data area of the L channel or the R channel, are called a sound frame.
[0040]
<3. U-TOC Sector>
As described above, when performing a recording / reproducing operation on the disc 1, the system controller 11 reads out P-TOC and U-TOC (user TOC) as management information recorded on the disc 1, Will be referred to.
Here, the U-TOC sector will be described as management information for managing the recording / reproducing operation of a track (musical piece or the like) on the disc 1.
[0041]
U-TOC and P-TOC are provided as TOC information. This P-TOC is formed in the innermost pit area of the disc 1 and is read-only information. Then, the location of the recordable area (recordable user area), lead-out area, U-TOC area, etc. of the disc is managed by the P-TOC. In the mini-disc system, a read-only optical disc in which all data is recorded in a pit form can be used. However, in the case of a read-only disc, management of music recorded in ROM by P-TOC is also possible. The U-TOC is not formed.
A detailed description of the P-TOC is omitted, and here, the U-TOC provided in the recordable magneto-optical disk will be described.
[0042]
FIG. 4 shows the format of U-TOC sector 0.
The U-TOC sector can be provided from sector 0 to sector 7. As will be described later, sector 1 and sector 4 are character information, and sector 2 is an area for recording recording date and time.
First, the U-TOC sector 0 that is absolutely necessary for the recording / reproducing operation of the disc 1 will be described.
[0043]
The U-TOC sector 0 is a data area in which management information is recorded mainly on music recorded by the user and free areas where new music can be recorded.
For example, when recording a certain piece of music on the disk 1, the system controller 11 searches for a free area on the disk from the U-TOC sector 0 and records audio data therein. Further, at the time of reproduction, the area where the music to be reproduced is recorded is determined from the U-TOC sector 0, and the area is accessed to perform the reproduction operation.
[0044]
In the data area (4 bytes × 588 2352 bytes) of the U-TOC sector 0, a synchronization pattern in which 1 byte data of all 0s or all 1s are formed side by side is recorded at the head position.
Subsequently, 4 bytes are added to the address which becomes the cluster address (Cluster H) (Cluster L) and the sector address (Sector) and the mode information (MODE), and the header is thus obtained.
[0045]
As described above, a sector is a data unit of 2352 bytes, and 36 sectors constitute one cluster. The synchronization pattern and address are recorded not only in the U-TOC sector 0 but also in the P-TOC sector and the data sector in which audio data is actually recorded, in the sector unit.
The cluster address is described by 2 bytes of an upper address (Cluster H) and a lower address (Cluster L), and the sector address (Sector) is described by 1 byte.
Next, at the specified byte position, manufacturer code, model code, track number of the first track (First TNO), track number of the last track (Last TNO), sector usage status (Used sectors), disk serial number, disk ID, etc. Data is recorded.
[0046]
Further, various table pointers (P) are used as the correspondence table instruction data portion in order to identify the track (music piece) area and free area recorded by the user by associating them with the management table portion described later. -DFA, P-EMPTY, P-FRA, P-TNO1 to P-TNO255) are recorded.
[0047]
Then, 255 parts tables (01h) to (FFh) are provided as management table sections corresponding to the table pointers (P-DFA to P-TNO255). Each part table has a certain part. The start address as the starting point, the end address as the end, and the mode information (track mode) of the part are recorded. In addition, since the parts shown in each part table may be connected to other parts in succession, link information indicating the part table in which the start address and end address of the connected part are recorded can be recorded. Has been.
In the present specification, the numerical value with “h” is a so-called hexadecimal notation. A part refers to a track portion in which temporally continuous data is physically continuously recorded in one track.
[0048]
In this type of recording / reproducing apparatus, even if the data of one music is physically discontinuous, that is, recorded over a plurality of parts, it is possible to reproduce while accessing between the parts, so there is no problem in the reproducing operation. The music recorded by the user may be recorded in multiple parts for the purpose of efficient use of the recordable area.
[0049]
For this reason, link information is provided, and the part tables can be connected by designating the part tables to be connected by, for example, the numbers (01h) to (FFh) given to the respective part tables.
In other words, in the management table section in the U-TOC sector 0, one part table represents one part. For example, for music composed of three parts connected, three parts connected by link information. The part position is managed by the table.
Actually, the link information is indicated by a numerical value that is a byte position in the U-TOC sector 0 by a predetermined calculation process. That is, the part table is designated as 304+ (link information) × 8 (byte).
[0050]
Each part table from (01h) to (FFh) in the management table part of U-TOC sector 0 is the table pointer (P-DFA, P-EMPTY, P-FRA, P-TNO1-P in the corresponding table instruction data part) -TNO255) shows the contents of the part as follows:
[0051]
The table pointer P-DFA indicates a defect area on the magneto-optical disk 1 and is the head of one part table or a plurality of part tables indicating a track portion (= part) that becomes a defect area due to a scratch or the like. The parts table is specified. In other words, if there is a defective part, one of (01h) to (FFh) is recorded in the table pointer P-DFA, and the defective part is indicated by the start and end addresses in the corresponding parts table. . When there are other defective parts, other part tables are designated as link information in the parts table, and the defective parts are also indicated in the parts table. If there is no other defective part, the link information is, for example, “(00h)”, and there is no link thereafter.
[0052]
The table pointer P-EMPTY indicates the first part table of one or more unused part tables in the management table section. If there is an unused part table, the table pointer P-EMPTY is (01h ) ~ (FFh) is recorded. When there are multiple unused part tables, the part tables are specified sequentially by link information from the part table specified by the table pointer P-EMPTY, and all unused part tables are linked on the management table section. Is done.
[0053]
The table pointer P-FRA indicates a free area (including an erasure area) in which data can be written on the magneto-optical disk 1, and one or a plurality of parts indicating a track portion (= part) as a free area. The first part table in the table is specified. In other words, if there is a free area, one of (01h) to (FFh) is recorded in the table pointer P-FRA, and the part table corresponding to it is indicated by the start and end addresses. Has been. Further, when there are a plurality of such parts, that is, there are a plurality of parts tables, the part information in which the link information is “(00h)” is sequentially designated by the link information.
[0054]
FIG. 5 schematically shows the management state of parts that become free areas, using a parts table. This means that when the parts (03h) (18h) (1Fh) (2Bh) (E3h) are free areas, this state continues from the table pointer P-FRA to the parts table (03h) (18h) (1Fh) (2Bh ) (E3h) indicates the state represented by the link. The management form of the above-described defective area and unused parts table is the same as this.
[0055]
By the way, if the magneto-optical disc has no recording of audio data such as music and has no defects, the parts table (01h) is specified by the table pointer P-FRA, which makes the entire recordable user area of the disc. Is shown as a free area. In this case, since the remaining (02h) to (FFh) part tables are not used, the part table (02h) is specified by the table pointer P-EMPTY described above, and the part table (02h) The parts table (03h) is specified as the link information, and so on. In this case, the link information of the parts table (FFh) is “(00h)” indicating no connection thereafter.
At this time, in the parts table (01h), the start address of the recordable user area is recorded as the start address, and the address immediately before the lead-out start address is recorded as the end address.
[0056]
Table pointers P-TNO1 to P-TNO255 indicate tracks such as music recorded by the user on the magneto-optical disk 1. For example, the table pointer P-TNO1 is one or more in which data of the first track is recorded. The part table that shows the first part among the parts is specified.
For example, when the music set as the first track is recorded on the disc without being divided, that is, recorded as one part, the recording area of the first track is the part table indicated by the table pointer P-TNO1. Recorded as start and end addresses.
[0057]
Further, for example, when the music set as the second track is discretely recorded on a plurality of parts on the disc, each part is designated according to the temporal order to indicate the recording position of the second track. In other words, from the part table specified in the table pointer P-TNO2, other part tables are further specified in accordance with the time order in accordance with the link information, and the part table in which the link information becomes “(00h)” is linked. (The same form as in FIG. 5 above).
In this way, for example, all the parts in which the data constituting the second music is recorded are sequentially designated and recorded, so that the data of the U-TOC sector 0 is used to reproduce the second music or the second music. When overwriting recording is performed on this area, it is possible to access the optical head 3 and the magnetic head 6 to extract continuous music information from discrete parts, or to record using the recording area efficiently.
[0058]
As described above, with respect to the rewritable magneto-optical disk 1, area management on the disk is performed by the P-TOC, and music and free areas recorded in the recordable user area are performed by the U-TOC.
[0059]
Next, FIG. 6 shows the format of the U-TOC sector 1. The sector 1 is a data area for recording input character information when a track name is given to each recorded track or a disc title is given.
[0060]
In this U-TOC sector 1, slot pointers P-TNA1 to P-TNA255 are prepared as character slot instruction data portions corresponding to the recorded tracks, and designated by the slot pointers P-TNA1 to P-TNA255. The character slot portion is prepared as slots (01h) to (FFh) each consisting of 8 bytes and 255 units, and manages character data in the same form as the U-TOC sector 0 described above.
[0061]
In the slots (01h) to (FFh), character information as a disc title or track name is recorded in ASCII code. The 8 bytes before the slot (01h) are a dedicated area for the disk name.
For example, characters input by the user corresponding to the first track are recorded in the slot designated by the slot pointer P-TNA1. In addition, since the slots are linked by the link information, the character input corresponding to one track can be handled even if it is larger than 7 bytes (7 characters).
In the U-TOC sector 1, the slot pointer P-EMPTY is used to manage unused parts tables.
[0062]
FIG. 7 shows the format of the U-TOC sector 4.
The U-TOC sector 4 is a data area for recording input character information when a song name is given to a song recorded by the user or a disc title is given, as in the sector 1 described above. Since it is almost the same as 6, the illustration is omitted.
However, in this sector, code data corresponding to Chinese characters and European characters is recorded, and in addition to the data of sector 1 in FIG. 6, an attribute of a character code used as a character code is recorded at a predetermined byte position. .
The management of the character information of the U-TOC sector 4 is performed in 255 units designated by the slot pointers P-TNA1 to P-TNA255 and the slot pointers P-TNA1 to P-TNA255 as the character slot instruction data portion in the same manner as the sector 1. This is performed by slots (01h) to (FFh).
[0063]
In addition to the U-TOC sector 1 and the sector 4, the U-TOC sector 2 is defined as a data area for recording the recording date and time of the music mainly recorded by the user. Omitted.
[0064]
<4. Overview of name copy mode>
Next, a user operation example in the name copy mode according to the present embodiment and a transition of the management state of the U-TOC updated by this operation will be described with reference to FIGS. Here, it is assumed that the ASCII code corresponds to the character information, and therefore, as an update process in the name copy mode, a case where the update process is performed on the U-TOC sector 1 shown in FIG. 6 will be described.
[0065]
FIG. 8 shows an example of an operation by the user for performing name copying, along with a transition example of the display form on the display unit 20.
For example, in order to copy at least a desired name in advance, the user is in a state in which a disc 1 on which character information (disc name or track name) as a copy source is recorded is loaded.
Thereafter, the user operates the edit key 29 or the like to select a menu screen corresponding to the name mode for performing the required editing related to the name from among the various editing modes described above. When the menu screen of the name mode is selected by this operation, for example, “Name?” Is displayed on the display unit 20 shown in FIG. ”Is displayed to confirm that the current name mode is a candidate.
Thereafter, for example, when the user performs an enter operation by pressing the yes key 30 or the jog dial 27 or the like, it is determined that the mode is changed to the name mode. The display shifts to a display for prompting selection of a desired mode from among name input, name erase and name copy modes. For example, when the name copy mode is selected as a candidate by pressing the edit key 29, for example, as shown in FIG. 8B, “Nm Copy? ] To prompt confirmation that the current name copy mode is a candidate.
[0066]
Under the display state of the display unit 20 shown in FIG. 8B, for example, the name copy mode is determined by performing an enter operation. Accordingly, the display unit 20 selects and designates a copy source. It will shift to display. Here, the user selects and designates the disc name or track name in which the character information to be copied is registered by a required operation. For example, if the disc name is designated, for example, the upper part of FIG. As shown, the display unit 20 displays “Nm CpyDisc” to indicate that the disc name is designated as copy source character information.
Further, for example, when the track name is selected and specified as the copy source, and track # 1 is specified, for example, “Nm Cpy Tr1” is displayed on the display unit 20 as shown in the lower part of FIG. Is displayed to indicate that the track name of track # 1 is currently designated as the copy source.
[0067]
Of course, there are discs or tracks for which no name has been registered, but there is no point in designating such a disc or track as the copy source. When a track is designated as a copy source, for example, “Disc: No Name” or “Tr1: No Name” is displayed to confirm to the user by displaying a warning indicating that the name is not registered. Is preferably obtained.
[0068]
Next, after confirming that the copy source selected and designated is correct by the display as shown in FIG. 8C, the user performs an enter operation for confirming the designation of the copy source.
[0069]
In the present embodiment, as described above with reference to FIG. 2, the work RAM 11a temporarily stores the character information selected and determined as the copy source. After the enter operation for confirming the designation, it is possible to perform name copy for the disc 1 different from the copy source by exchanging the loaded disc. For this reason, if the user intends to copy the name to another disc different from the copy source, after the copy source selection confirmation enter operation, the copy source disc is taken out from the disc insertion section 22 and another disc is selected. It is only necessary to load the disc as if it was replaced.
If a changer configuration capable of loading a plurality of discs is employed as the recording / reproducing apparatus, another disc required as a copy destination is selected from the loaded discs according to a required operation. It is possible to do.
Of course, when the copy source disk and the copy destination disk are the same, it is not necessary to replace the disk.
[0070]
After performing the enter operation for confirming the designation of the copy source as described above and replacing the disk 1 as necessary, the user performs an operation for designating the copy destination according to a predetermined key operation. Do.
For example, if the disc name is designated as the copy source in the operation procedure in FIG. 8C and the track # 3 is designated as the copy destination, for example, “Disc →→→ Tr3” (see FIG. As shown in FIG. 8D, a display showing the correspondence between the copy source and the copy destination is performed.
[0071]
For example, the user sees the display shown in FIG. 8D and confirms that there is no mistake in the designation of the copy source and the copy destination so far, and performs the enter operation. Thereby, a name copy process is executed. That is, in this case, the character information as the disc name designated as the copy source is registered as the character information of the track name of track # 3. At this time, for example, “Complete” is displayed on the display unit 20 as shown in FIG. 8E to indicate that the name copy process has been completed.
[0072]
9 and 10 show the transition of the management state of the U-TOC sector 1 when the disk name is copied as the track name of the track # 3 as described above. Here, the character slot instruction data is shown. And the character slot part are shown.
[0073]
FIG. 9 shows an example of a management state of the U-TOC sector 1 before name copying. In this case, the disk name and the track names up to track # 1 and track # 2 are registered, and the track names after track # 3 are not registered yet. Here, it is assumed that the disc name is 9 characters “DANGEROUS” and that each track name of track # 1 and track # 2 stores some character information within 7 characters.
In this case, the character information from “DANGEROUS” up to “DANGERO” for 7 characters from the beginning is stored in the slot of the disk name, and the remaining for the first 2 bytes of the slot (01h) linked by the link information Two characters "US" are stored. Note that “00h” (indicated by “−” in the figure) is stored in the remaining 5 bytes in the slot (01h) to indicate that there is no character information. The link information of the slot (01h) is “00h” to indicate the end of connection.
In this case, the track name of the track # 1 is stored in the slot (02h) indicated by the table pointer P-TNA1: 02h, and the link information of the slot (02h) is set to “00h”, indicating that there is no subsequent connection. Show. The track name of track # 2 is stored in the slot (03h) indicated by the table pointer P-TNA2: 03h. Here, the link information of the slot (03h) is “00h” and there is no subsequent connection. Is shown.
In this case, the slot (04h) to slot (FFh) indicated by the table pointer P-EMPTY: 04h are linked by the link information and set as an unrecorded (stored) area. In this case, “00h” is set after the table pointer P-TNA3.
[0074]
FIG. 10 shows the management state of the U-TOC sector 1 updated from the management state shown in FIG. 9 based on the name copy operation example described in FIG. The description of the same parts as those in FIG. 9 is omitted.
In this case, “DANGEROUS”, which is the same as the disk name, is stored over the slot (04h) → (05h), which was an unstored area before the name copy. That is, “04h” is set in the table pointer P-TNA3, and seven characters up to “DANGERO” are stored in the slot (04h) indicated thereby. Then, the remaining two characters “US” are stored in the slot (05h) connected by the link information “05h” of the slot (04h), and the link information of the slot (05h) indicates “no connection” thereafter. 00h ”is set.
Along with this, the table pointer P-EMPTY is updated to “06h”, and the slot (06h) to slot (FFh) indicated thereby are linked by the link information and set as an unstored area.
[0075]
11 and 12 show another example of the management state of the U-TOC sector 1 when the disk name is copied as the track name of the track # 3 as in FIGS. It shows the transition.
[0076]
FIG. 11 shows an example of the management state of the U-TOC sector 1 before name copying, which is different from FIG. 9. In this case, the disk name and the track names from track # 1 to track # 4 are registered. It has been done. Here, the disc name is 9 characters “DANGEROUS”, and the track names of track # 1 to track # 4 store some character information within 7 characters.
Also in this figure, the disk name slot stores the character information from the beginning of “DANGEROUS” up to 7 characters “DANGERO”, and for the first 2 bytes of the slot (01h) linked by the link information The remaining two characters “US” are stored, and the link information thereof is “00h” to indicate the end of the connection.
The track name of the track # 1 is stored in the slot (02h) indicated by the table pointer P-TNA1: 02h, and the link information of the slot (02h) is set to “00h” to indicate no connection thereafter. Similarly, the track name of the track # 2 is stored in the slot (03h) indicated by the table pointer P-TNA2: 03h, and the link information is set to “00h” to indicate no connection thereafter. The track name of the track # 3 is stored in the slot (04h) indicated by the table pointer P-TNA3: 04h, and its link information is set to “00h” to indicate that no connection is made thereafter. The track name of the track # 4 is stored in the slot (05h) indicated by the table pointer P-TNA4: 05h, and its link information is set to “00h” to indicate no connection.
Therefore, in this case, “06h” is set in the table pointer P-EMPTY, and the slot (06h) to slot (FFh) indicated thereby are linked by the link information and set as an unstored area. Yes. In this case, “00h” is set for the table pointer P-TNA 5 and later.
[0077]
FIG. 12 shows the management state of the U-TOC sector 1 updated by name copy from the state shown in FIG. 11, and the description of the same parts as those in FIG. 11 is omitted.
In this case, as a result, for the slot (04h) in which the track name of track # 3 was stored before the name copy, the first 7 characters of the “DANGEROUS” character information identical to the disc name are stored. Character information up to “DANGERO” for the character is stored, and the remaining two characters “US” are stored in the slot (06h) that was the first slot in the unstored area before the name copy. .
As a result, the link information of the slot (04h) is changed to “06h” to indicate that it is connected to the slot (06h). Then, “00h” indicating no connection is set for the link information of the slot (06h).
Along with this, the table pointer P-EMPTY is updated to “07h”, and the setting is changed so that the slot (07h) to slot (FFh) indicated thereby are linked by the link information and become an unrecorded area. The
[0078]
The process of updating the U-TOC sector 1 as shown in FIGS. 9 to 10 or 11 to 12 is performed on the data of the U-TOC sector 1 held in the buffer memory 13 as described above. The U-TOC update (rewrite) process on the actual disk 1 is performed at a predetermined opportunity set in advance.
In addition, for example, when the U-TOC sector 4 is used when the character information is Kanji or European characters, the management state described with reference to FIGS. 9 to 12 is applied.
[0079]
<5. Processing operation in name copy mode>
Next, processing operations for realizing the above-described name copy mode will be described with reference to FIG. The processing operation shown in this figure is executed by the system controller 11.
In the routine shown in this figure, first, in step S101, for example, the setting of the name copy mode which is performed by the operation procedure described in FIGS. 8A and 8B is awaited. Here, the name copy mode is set. If it is determined that the process has been performed, the process proceeds to step S102 as the first process for shifting to the name copy mode.
In step S102, the process waits for the copy source designation confirmed by the operation procedure described with reference to FIG. 8C. When it is determined that the copy source designation is confirmed, the process proceeds to step S103, and the work is performed. A control process for writing and temporarily storing name data (character information) as a copy source in the RAM 11a is executed.
[0080]
In the name copy mode of the present embodiment, the disk to be loaded may be replaced after the process of step S103 is completed, that is, after the designation of the copy source is confirmed. At this stage, for example, when the eject key 34 is operated to eject a disk loaded so far, the system controller 11 executes a process for ejection.
Then, when a new copy destination disk is loaded, control is executed so that the read operation for the U-TOC area of this disk is once performed, and the U-TOC read from the disk is stored in the buffer memory. 13 is executed. In addition, illustration by the flowchart etc. about the processing operation of the system controller 11 accompanying such disk exchange is abbreviate | omitted for convenience of explanation.
[0081]
In step S104 following step S103, the process waits for the designation of the copy destination to be confirmed by the operation procedure described in FIG. 8D, for example, and it is determined that the designation of the copy destination has been confirmed. Then, it progresses to step S105. In step S105, it is determined whether the copy destination specified in step S104 is a disk name or a track name. If it is a track name, the process proceeds to step S106 and subsequent steps. In step S115, the process proceeds to step S115 and subsequent steps.
[0082]
In step S106, if the track number of the track designated as the copy destination is #x, whether or not the corresponding table pointer P-TNA x is set to “00h”, that is, the track #x has already been registered. It is determined whether or not a track name already exists.
Here, when it is determined that the table pointer P-TNA x is “00h”, that is, no name is registered for the track #x designated as the copy destination (corresponding to the case of FIG. 9). The process proceeds to step S107, and the process of setting the value of the table pointer P-TNA x to the current value of the table pointer P-EMPTY is performed. That is, here, a process for considering the slot indicated by the table pointer P-TNA x as the head slot of the unstored area is performed.
[0083]
On the other hand, if it is determined in step S106 that there is already a registered track name for track #x (corresponding to the case of FIG. 11), the process proceeds to step S108, and the table pointer P-TNA x is used. The link information “00h” in the last slot linked by the link information is changed to the value set as the current table pointer P-EMPTY. In the subsequent step S109, processing for changing the current value of the table pointer P-EMPTY to the value of the table pointer P-TNAX is performed.
In this case, the processing for considering the slot indicated by the table pointer P-TNAX as the leading slot of the unstored area is performed by the processing of steps S108 and S109.
After the process of step S107 or step S109 is completed as described above, the process proceeds to step S110.
[0084]
In step S110, the character information forming the name data is copied (stored) from the head for the slot indicated by the current table pointer P-TNA x. Then, in the next step S111, it is determined whether or not there is a remaining name data that could not be stored in the previous step S110.
If it is determined in step S111 that the remaining name data exists, the remaining name data is sequentially stored in the slots linked to the previously copied slot, and the process returns to step S111 again. By executing the processing of steps S110 to S112 in this way, if the name data is 7 characters or more, it is sequentially stored in the slots linked by the link information.
If it is determined in step S111 that there is no remaining name data, that is, the storage processing of the name data in the slot is completed, the process proceeds to step S113.
[0085]
In step S113, at the present stage, the address of the slot linked next to the last slot in which the name data has been copied (however, if the name data is within 7 characters, the slot is the first slot) is used as the table pointer. Processing to set as the value of P-EMPTY is performed. In the subsequent step S114, the link information of the last slot to which the name data has been copied is set to be “00h”, and then the name copy mode is terminated to exit this routine.
[0086]
In step S115, which is the first process when the copy destination is a disk name, the link information “00h” of the last slot linked by the link information from the disk name slot is used as the current table pointer P-EMPTY. Change to the value set as. As a result, the disk name dedicated slot is temporarily connected to the unstored area indicated by the table pointer P-EMPTY, or the end slot of the slot group in which the disk name is already stored is set to the table pointer P. By linking to the non-storage area indicated by -EMPTY, it becomes possible to treat the slot linked from the disk name slot as a disk name copyable area.
[0087]
Then, in the subsequent step S116, the process of sequentially copying the name data held in the work RAM 11a from the first character to the disk name slot is executed, and then the process proceeds to the above-described steps after step S111. To be.
If an instruction to cancel the name copy mode is obtained, for example, by operating the cancel key 31 during the processing operation shown in this figure, the name copy mode is terminated by immediately exiting this routine. However, the illustration of the processing operation relating to this is omitted.
[0088]
Note that the processing operation illustrated in FIG. 13 is merely an example, and the processing operation may be performed by another type of processing operation. In the above embodiment, the case where the editing apparatus of the present invention is applied to a recording / reproducing apparatus has been described. However, the present invention is not limited to this, and can also be applied to a recording or reproducing apparatus. Furthermore, it may be configured as an editing-dedicated device configured to execute at least the editing operation (name copy function) described so far.
Further, the present invention is not limited to the mini-disc system mentioned as the embodiment, but can be applied to other various disc recording / reproducing apparatuses, and further to other types of recording media such as tape-like recording media. The present invention can also be applied as an editing device corresponding to recorded data.
[0089]
【The invention's effect】
