  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these embodiments.

[Configuration of MD device]
FIG. 1 is a schematic block diagram showing an identification information registration apparatus according to a preferred embodiment of the present invention by taking a mini disk (hereinafter referred to as MD) apparatus as an example. Based on the input from the user, the MD device 1 registers the identification information of the track (hereinafter sometimes referred to as music or content data) recorded on the MD and / or the identification information of the MD itself in the MD. The track identification information typically includes a track name (song name), an album name, an artist name, and a group name. The identification information of the MD itself typically includes a disc name. Note that the album name and artist name are names newly added in the Hi-MD (registered trademark, hereinafter the same) standard.

  The MD device 1 includes a control unit 2, an operation unit 3, and a display unit 4. The control unit 2 controls the operation of the entire MD device 1 and is typically a microcomputer (hereinafter referred to as a microcomputer). The control unit 2 executes each process (for example, FIGS. 2 and 4 described later) by executing each program stored in a built-in ROM (not shown), for example. For example, the control unit 2 registers character data input by the user as a name in the MD. Here, registering identification information in the MD means that a name is recorded in the U-TOC area of the MD so that the content can be managed by the recorded name (registration means), and a new name is simply added. This includes not only recording, but also changing or deleting names already recorded. Moreover, the control part 2 selects the category of the name which the display part 4 displays based on a user's operation (category selection means). Moreover, the control part 2 selects the content which the display part 4 displays based on a user's operation (content selection means).

  The operation unit 3 receives each instruction from the user and gives a signal based on the user's instruction to the control unit 2. For example, a key, a button, and / or a remote control provided on the MD device main body is adopted. obtain. The user registers each name in the MD using the operation unit 3.

  The display unit (display unit) 4 displays one of the names related to the selected (or reproduced) track, and is, for example, a liquid crystal display unit. Since the display unit 4 is provided on the front panel unit of the MD device 1 main body, it is not possible to display all names among a plurality of categories for the track, and only one track selected by the user is displayed. indicate. The display unit 4 displays the contents for registering each name of the track (hereinafter referred to as a registration screen, details will be described later).

  A servo circuit 5 for accessing the MD is connected to the control unit 2. A head unit 6 and an RF amplifier 7 are connected to the servo circuit 5. The head unit 6 includes a spindle that rotates an MD (internal disk), a pickup that reads and writes data recorded on the MD, and the like (not shown). The servo circuit 5 controls the head unit 6 based on an instruction from the control unit 2.

  The RF amplifier 7 amplifies the signal sent from the head unit 6 via the servo circuit 5 and supplies the amplified signal to the address decoder 8. The address decoder 8 decodes the song address based on the signal from the head unit 6 and provides the decoded signal to the signal processing unit 9. This address is used for each process.

  A signal processing unit 9 and a memory control circuit 10 are connected to the control unit 2. The signal processing unit 9 performs compression encoding and decoding of music. A DAC (Digital Analog Converter) 11 and an ADC (Analog Digital Converter) 12 are connected to the signal processing unit 9. The DAC 11 converts the digital data from the signal processing unit 9 into analog data and supplies it to the analog output terminal. The ADC 12 converts analog data input from the analog input terminal into digital data and supplies the digital data to the signal processing unit 9.

  The memory control circuit 10 connects the memory 13 and controls the memory 13 based on an instruction from the control unit 2. The memory 13 is composed of, for example, a DRAM, and functions as a buffer memory for recording and reproducing music or registering names.

  The control unit 2 has a built-in RAM 14. The control unit 2 temporarily stores character data input by the user in the RAM 14 and displays the input character data on the display unit 4 as a name. When the input of the character data is completed, the character data stored in the RAM 14 is given to the memory 13, and the character data is registered as a name in the memory 13.

[Composition of character data for each name]
Table 1 is a table for explaining each name registered in each track. Corresponding to each track number, a track name, album name and artist name are registered. Table 2 is a table for explaining group names registered in each group. A group is a group of a plurality of tracks having the same attribute to facilitate track management. For example, the group of group number 1 includes tracks 1 to 7 and the group of group number 2 indicates that tracks 8 to 14 are included. The group name is registered for each group, not for each track. For this reason, when one track in the group is selected and the group name is registered, it is not necessary to register the group name for the other tracks in the group. The character data in Tables 1 and 2 are read from the MD and stored in the memory 13 when the MD is inserted into the MD device. Also, name types such as track names, album names, artist names, group names, and disc names are called name categories.

[Name registration process]
A process in which a user inputs character data of a name (in this example, an album name) using the operation unit 3 and registers the data in the MD will be described with reference to FIG. One track is selected from a plurality of tracks recorded on the MD, and the album name of the selected track is registered. First, the control unit 2 selects one desired track for registering a name from the tracks recorded on the MD (S201). Specifically, since the names (Table 1 and Table 2) relating to the track are stored in the memory 13 as described above, the name or the track number relating to the selected track is read from the memory 13 in accordance with a user operation. Displayed on the display unit 4.

  Based on the user's operation, the control unit 2 selects one category to be displayed on the display unit 4 from each category of the name related to the selected track (S202). Specifically, one name is selected from the track name, album name, artist name, and group name according to the user's operation and displayed on the display unit 4. As shown in FIG. 3, the display screen of the display unit 4 is switched in the order of the track name 301, the album name 302, the artist name 303, and the group name 304 every time the user operates the operation unit 3. In this example, the album name 302 is selected by a user operation. When the album name is selected, the control unit 2 sets an album name flag (not shown). This is because the control unit 2 determines which category is selected. In the example of FIG. 3, the track name, artist name, and group name are registered and displayed on the display unit 4, but the album name is not registered and is not displayed on the display unit 4 (in a blank state). ).

  When the user operates the operation unit 3 to input a name registration instruction, the control unit 2 receives the name registration instruction signal from the operation unit 3 and directly shifts to the name registration state (S203). Transitioning to the name registration state means that character data can be received by a user operation. Specifically, the control unit 2 shifts to a name registration state in which the category names selected in S202 and displayed on the display unit 4 among the names of the tracks selected in S201 can be registered. That is, in this example, since the album name is selected, the process shifts to an album name registration state. Further, “directly shifting” means shifting to a registered state without asking the user which category name to register.

  Details of the process of S203 will be described with reference to FIG. Here, the category selected in S202 is determined in S401 to S403, and the state shifts to a name registration state in which the name of the determined category can be registered. As described above, which category is selected in S202 is determined by the presence / absence of a flag set. In this example, since the album name is selected, the control unit 2 determines NO in S401 and S402, and determines that the album name is selected in S403 (S403: YES). As a result, the control unit 2 shifts to an album name registration state (S406). Specifically, the control unit 2 causes the display unit 4 to display a registration screen for registering an album name. In the registration screen, as shown in FIG. 5, the category (album name) currently registered is shown on the lower right side of the display unit 4, and an underbar is added to a character part (indicated by an arrow) entered by the user. . The control unit 2 reads the album name of the selected track from the memory 13 and displays it on the display unit 4, thereby generating the registration screen of FIG. 5. However, in this example, since the album name is not registered, the album name is not displayed and is blank.

  Similarly, if a group name is selected (S401: YES), a registration screen for registering the group name is displayed on the display unit 4, and the control unit 2 shifts to a registration state for registering the group name ( S404). If the artist name is selected (S402: YES), a registration screen for registering the artist name is displayed on the display unit 4, and the control unit 2 shifts to a registration state for registering the artist name (S405). If it is determined in S403 that no album name is selected, the control unit 2 determines that the remaining track name is selected. As a result, a registration screen for registering track names is displayed on the display unit 4, and the control unit 2 shifts to a registration state for registering track names.

  Returning to FIG. 2, when the user operates the operation unit 3 to input character data (album name), the control unit 2 receives the character data input from the operation unit 3 (S204). The character data is temporarily stored in the RAM 14 and the input character data is displayed on the registration screen of the display unit 4.

  Upon receiving an input end instruction from the user, the control unit 2 registers the album name of the designated track in the MD (S205). Specifically, the input character data is given to the memory 13 and registered in the table of Table 1 or Table 2 in the memory 13. Thereafter, for example, when the MD is taken out (or when the reproduction state is changed to the stop state), the tables in Tables 1 and 2 are read from the memory 13 and written in the MD.

  As described above, when the user inputs a name registration instruction in a state where the name is displayed on the display unit 4, a registration screen for registering the name of the category corresponding to the category of the name currently displayed is displayed on the display unit 4. Is displayed. In other words, a screen for inquiring the user of which category name to register is not displayed on the display unit 4, but a direct registration screen is displayed. Therefore, the user's name registration operation is very easy to understand and extremely easy.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. For example, the case where a name that has not yet been registered is registered has been described as an example, but the same applies to the case where a name that has already been registered is changed or deleted. In this case, the registered name is displayed on the registration screen of FIG. 5, and an underbar is added to the portion of the character to be changed. Furthermore, the category of the name is not limited to the above, but may be a genre name or the like. Furthermore, the control unit may include a system control unit that controls the operation unit and the display unit, and a mechanical control unit that controls other parts. The present invention can also be provided in the form of a computer program for causing a computer to execute the above operations.

  The present invention can be suitably employed in various electronic devices that register identification information such as names regarding content data.
