Abstract

There is a problem that a finalizing process takes a long time.
When a disc recorded in real time video information or a simple format is finalized, a recording amount of a lead-out area can be designated by a user. Furthermore, the lead-out area can be additionally recorded by the user. In addition, the recording of the lead-out area is performed at a higher speed than the recording of the video information, and at the same time, the required recording power is reduced to realize a high-speed finalizing process.

Description

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording device for a disk recording medium such as a write-once recording disk or a rewritable recording disk with a limited number of rewrites, and in particular, to a finalizing means and an information recording device using the same.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a method of recording video information on a disk-shaped recording medium, there is a real-time video recording format as an application that performs real-time video recording and can easily perform editing processing after recording. This is a standard that allows TV broadcasts and the like to be recorded simultaneously with the broadcast, and that editing and erasing after recording can be easily performed.
[0003]
On the other hand, the video format used in commercially available software that is assumed to be viewed on a commercially available DVD player is different from the video recording format because it is considered that editing processing is performed before recording. For this reason, there is a problem that a disc recorded in the video recording format cannot be viewed on a commercially available DVD player.
[0004]
In view of this, a method has been proposed in which information is temporarily recorded in a simple format in real time, and the recording management data conforming to the standard video format is re-recorded by performing finalization processing at the end. (For example, see Patent Document 1)
However, in the finalizing process, it is necessary to record up to a predetermined area, and when a disc on which information is recorded only in a small area is finalized, a lead-out area for recording predetermined data in the remaining area increases. The finalization process takes time. Therefore, it has been proposed to record this area at high speed or to record continuously. (For example, see Patent Document 2)

[Problems to be solved by the invention]
In the above-mentioned prior art, when the present disk recording apparatus is employed in a small-sized portable device, no consideration has been given particularly to a factor of performance instability due to a rise in temperature. In particular, in a medium using a dye-based recording medium (for example, a DVD-R), it is necessary to secure recording power, and in particular, by increasing the finalizing speed to shorten the finalizing time, the recording power is further increased. When the device needs to be operated continuously, the temperature rise of the entire device of a small portable device causes a further problem.
[0007]
For example, in the finalizing process of a disc such as a DVD-R or a DVD-RW, if only a small amount of information is recorded on the recording disc, the disc is read to a predetermined position in a free area of the disc in consideration of reproduction by a DVD player. Out data needs to be recorded. This time may require several minutes or more, and if continuous recording operation is performed with a small portable device, a sudden rise in temperature may occur, making it impossible to ensure the performance of each component of the device, and the finalization process may not be completed correctly. May occur.
[0008]
As a further problem, in the case of a small portable device, it is naturally necessary to reduce the shape of the optical system for recording on the disc. There is a problem that it is not possible to record at such a high recording power.
[0009]
Further, when considering the vibration and noise accompanying the high-speed rotation of the optical disc, for example, in an image and sound recording device such as a video camera, recording is performed at a high speed at least during recording of video and audio because of the noise and vibration. I can't do that.
[0010]
On the other hand, the reason why a lead-out data recording area for recording lead-out data up to a predetermined position in a free area of a disk in consideration of reproduction by a DVD player is necessary is as follows. That is, since the servo method of the DVD player generates a servo signal on the assumption that the recording data is written, if the recording data is not written, the servo control is lost, and the position control of the optical head is performed. Can not be done. Therefore, a predetermined amount of lead-out data is recorded after valid recording information to prevent a servo signal from being unable to be generated.
[0011]
In particular, in the case of an 8 cm disk, the recording amount is required to be about 7 cm in radius. However, in the case of performing finalization processing for recording on a DVD player after recording user information of about several megabytes, for example, it is necessary to record lead-out data up to a diameter of 7 cm, and the finalization processing time is wasted. is there. In addition, it can be said that reproduction is not possible unless all DVD players have recorded lead-out data up to a diameter of 7 cm. There is no such a case, and after recording data is completed, recording can be performed sufficiently by recording lead-out data of about 2 mm. It is.
[0012]
An object of the present invention is to complete a finalizing process of a disk recording device at high speed in a short time. In other words, the purpose is to realize a finalizing process as fast as the device allows.
Further, the present invention provides a device in which these disk devices are applied to a camera-integrated recording device, a portable information processing device, and a monitor-integrated device.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, recording means for recording video information on a recording medium, finalizing processing means for recording at least lead-out data by finalizing the recording medium, and signal quality during the recording operation of the lead-out data. Switching means for switching a method of performing high-speed recording with priority on recording time, temperature detecting means for detecting a temperature change of the present apparatus, and stopping means for temporarily stopping the finalizing processing means according to an output of the temperature detecting means. Operating means for externally changing the readout data amount, and means for stopping or terminating the finalizing process in the middle.
Further, additional recording means for additionally recording the lead-out data is provided on the finished finalized disk.
[0014]
Further, at the time of the recording operation of the recording data for recording the video information, the signal quality is prioritized over the recording time, and switching means for switching to an intermittent recording method in which a recording period and a recording stop period are periodically repeated, A temperature detecting means for detecting the temperature; and a power calibrating means for appropriately controlling a recording power value during a recording operation of the recording data during the recording stop period in accordance with an output of the temperature detecting means.
[0015]
The power calibration seeks to the actual power calibration area PCA, varies the recording power, and determines the optimum recording power. Alternatively, the temperature and the required power are tabulated in advance, and the table value is reflected at the time of the threshold temperature. Alternatively, it is performed by a combination of both.
[0016]
In the recording of the lead-out area, extra data is recorded so that the optical head does not overrun when reproducing the data recording area. Even if the quality of the recording signal is low, there is no problem.
[0017]
On the other hand, the recording speed and the required recording peak power when the recording waveform is optimally recorded on the optical disk at the recording speed are about the root of the recording speed. Therefore, although it takes a long recording time, the recording quality of the lead-out area, which does not require a very high data quality, can be shortened by slightly reducing the recording power and performing high-speed continuous recording. By doing so, it is possible to record a data recording area that can increase data reliability at low speed and intermittent recording, and to record a high-speed lead-out area.
[0018]
Further, in order to achieve the above object, a disk recording device provided with a finalizing device of the recording device is applied to a portable camera-integrated recording device.
Furthermore, in order to achieve the above object, the present invention is applied to a portable information processing device using a disk recording device provided with a finalizing device of the recording device.
Further, in order to achieve the above object, a monitor device for displaying a reproduced signal from the recording device is applied to a portable monitor-integrated video reproducing device.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0021]
In the case of a video camera, image data and audio data are continuously processed by five image signal processing means. The image quality and sound quality are determined by the processing capacity of the five image signal processing means. The transfer speed of data sent from the image signal processing means 5 to the recording / reproducing signal processing means 6 described later is determined. The above-described photographing unit 1, microphone 18, and image signal processing unit 5 are collectively referred to as a camera unit 21.
[0022]
Reference numeral 6 denotes a recording / reproducing signal processing means for converting image data (including audio data) from the image signal processing means 5 into recording data according to a recording format for recording on a disk-shaped recording medium 9, or In order to convert the recording data reproduced from the disc-shaped recording medium 9 into image data (including audio data), processing such as encoding / decoding processing, modulation / demodulation processing, and ECC addition / error correction processing is performed. The transfer speed of recording or reproduction on the disk is determined by the processing capability of the recording / reproduction signal processing means 6, the processing capability of the reproduction means 8, the rotation speed of the disk, and the like.
[0023]
Reference numeral 7 denotes a memory for temporarily storing image data (including audio data) from the image signal processing means 5. The memory is stored when the transfer speed of image data or audio data transferred from the image signal processing means 7 is higher than the speed of recording on the disk-shaped recording medium (optical disk) 9. Therefore, it is necessary to record the data on the optical disk 9 before the amount of data stored in the memory does not exceed the memory capacity.
[0024]
Reference numeral 8 denotes a reproducing means, 9 denotes an optical disk rotated and driven by a spindle motor (not shown), 10 denotes a laser 11 (laser diode), a laser driver 12 for driving the laser, an optical system (not shown), a photodetector 13 and light An optical head comprising an IV amplifier 14 and the like for converting a current value from a detector into a voltage value and amplifying the voltage value. The recording / reproducing signal processing means 6 records the recording data stored in the memory 7 on an optical disk. After converting (encoding) the recording signal into necessary recording information, the recording signal is transmitted to a laser driver 12 so that the recording signal becomes a predetermined recording signal on a disk. 9 is recorded with a predetermined recording signal.
[0025]
The recording signal on the optical disk 9 is read by the photodetector 13, amplified by the IV amplifier 14, converted into a servo signal and a reproduction signal by the reproduction unit 8, and then recorded and processed by the recording and reproduction signal processing unit 6. , And converted into reproduced recording data. The servo signal is converted into a servo control signal by the recording / reproducing signal processing means 6 and sent to 16 servo control means.

[0026]
Reference numeral 19 denotes an image display means such as an LCD. At the time of reproduction, data on the optical disk 9 read by the optical head 10 (data read by a photodetector of the optical head 10 using reflected light from the optical disk irradiated with laser light as a reflected light amount difference) is recorded. After being temporarily stored in the memory 7 as reproduced recording data via the reproducing means 8, it is converted into the original image data by the recording / reproducing signal processing means 6, and is transmitted to the image display means 19 via the image signal processing means 5. Is displayed.
[0027]
Reference numeral 17 denotes a system control unit including a control microcomputer that controls the entire apparatus. The system control unit 17 controls each unit of the apparatus and performs overall management.
[0028]
Here, the temperature sensor 15 is disposed near the optical head 10 that requires special attention to temperature rise. The temperature of the device is detected by the temperature sensor 15 and is taken into the system control means 17.
[0029]
Reference numeral 20 denotes an operation switch, which issues a user's instruction for image recording and reproduction, a finalization processing instruction, and the like. The instruction is sent to the control microcomputer 17, and the control microcomputer 17 controls the entire apparatus according to the instruction. The operation switch 20 is also used to switch the amount of lead-out data recorded in the finalizing process and to instruct additional writing of lead-out data on the finalized disk.
[0030]
Next, as an optical disk 9 for handling an image signal, for example, there is one as shown in FIG. There is a DVD-ROM for reproduction only, a DVD-R and a DVD + R as a write once type, and a rewritable medium such as a DVD-RW, a DVD + RW and a DVD-RAM. As a recording format, for example, a video format (DVD Video format) and a video recording format (Video recording format) have been proposed.
[0031]
The video format uses video information that has been sufficiently edited in advance, such as movies, to realize its own functions such as multi-angle, parental playback, random shuffle playback, and special playback such as fast forward and rewind. Have strong information data to support.
[0032]
In addition, the video recording format is intended for an application that can record a video signal in real time without any editing processing on the premise of this rewritable disc and can easily perform the editing processing after recording. However, there is a problem that many signals recorded in the video recording format cannot be reproduced by many DVD players for reproducing a reproduction-only disc recorded in the video format.
[0033]
The problem is that, especially when recording on a disc medium in a video camera, once a rewritable disc such as a DVD-RW or DVD-RAM is once recorded in a video recording format, an editing operation is performed, and the data is converted to the video format again. However, once a DVD-R disc is a write-once disc, which is recorded once in a video recording format, it cannot be rewritten and the disc cannot be re-recorded. Can not be played with.
[0034]
Therefore, in the DVD-R disc, a method is adopted in which information is temporarily recorded in a simple format in real time, and the recording management data conforming to the standard video format is re-recorded by performing a finalizing process at the end. . Hereinafter, a DVD-R disc will be described as an example, but it goes without saying that the same processing can be applied to a DVD + R, DVD-RW, DVD + RW or DVD-RAM disc. The concept is the same for Blu-ray discs.
[0035]
FIG. 3 schematically shows the data structure of a DVD disk. In a DVD that can be recorded and reproduced, the management areas include an R-information area (R-Information Area), a lead-in area (Lead-in Area), and a border-out / lead-out area (Border-out / Lead-out Area). The R-information area includes a power calibration area (Power Calibration Area) and a recording management area (Recording Management Area), but a lead-in area and a lead-in area. By making the content of the out area equal to that of the read-only DVD-ROM, compatibility of reproduction is ensured.
[0036]
Each time a process involving recording, such as recording new data in the data recording area or editing data recorded in the data recording area, is performed, predetermined recording management data is rewritten to these management areas. The recording state is managed by writing.
[0037]
An R-information area (R-Information Area: RIA) and an information area (Information Area: IA) are allocated to the data area of the disc from the radial inner side (clamping area CA side) to the radial outer side. ing.
[0038]
The R-information area RIA is composed of a power calibration area (Power Calibration Area: PCA) and a recording management area (Recording Management Area: RMA), and the information area IA is composed of a lead-in area (Lead-in Area: LIA). It is composed of a data recording area (Data Recordable Area: DRA) and a lead-out area (Lead-out Area: LOA). According to the DVD Forum standard, the lead-out area is required to record up to 70 mm when the end of the data recording area is 68 mm or less in diameter, and to record the lead-out area in 2 mm width when the end of the data recording area is 68 mm or more. However, even if the DVD player has a lead-out area of 2 mm width even if the diameter is 68 mm or less, the servo will not come off. In addition, for the user to enjoy individually, the recording area of the lead-out area does not particularly need to conform to the above-mentioned standard. What is necessary is just to follow the performance of the DVD player used by the user.
[0039]
Next, the operation of the finalizing process will be described with reference to FIGS.
In FIG. 1, when the user operates the operation switch 20, the operation of the finalizing process in FIG. 4 starts. First, in step 102, the end of the main data already recorded in the data recording area DRA, that is, the address of the start end of the lead-out area LOA is detected. After that, the minimum area of the lead-out area is recorded. The minimum lead-out recording area has a radius of about 1 mm.
[0040]
Next, in step 103, recording management data is recorded in the recording manager area RMA.
Next, in step 104, record management data as predetermined data indicating that the finalization has been performed is recorded in a predetermined area of the lead-in area LIA according to the standard format.
Next, in step 105, the remaining lead-out area LOA specified in advance by the user is additionally recorded. This record can be omitted by the user. Finally, the data is recorded up to a predetermined range of the lead-out area LOA in the standard format.
[0041]
As described above, when the finalizing process is performed, the recording management data is recorded on the loaded optical disk 9 in accordance with a user request, so that compatibility with a read-only DVD is ensured.
[0042]
In the normal finalization process, the lead-out area LOA is recorded to a predetermined range (for example, a diameter of 70 mm) in step 102 described above. For this reason, depending on the conditions, it is conceivable that a dozen minutes of finalization processing time is required. However, by employing the above method, the finalizing operation can be considerably shortened.
[0043]
Further, a method of shortening the finalizing process will be described below.
In the finalization process, the recording of the lead-out area LOA is for recording extra data so that the optical head 10 does not overrun when reproducing the data recording area DRA. Data is recorded as 00. Therefore, there is no problem even if the quality of the recording signal in the lead-out area LOA is low.
[0044]
Since the control microcomputer 17 manages the start of the recording operation of the lead-out area LOA during the execution of the finalizing process, the recording time is prioritized over the signal quality during the recording operation of the lead-out area LOA so that the recording is performed at high speed. Next, the recording method is switched. Generally, at the recording speed and the recording speed, the required recording peak power when the recording waveform is optimally recorded on the optical disk is approximately a root multiple of the recording speed as shown in FIG.
[0045]
Also, the jitter that determines the recording quality changes depending on the recording power. For example, the recording power of the user data recording unit that is particular about the recording quality is set to the recording power of 8%, and the readout area that is not particular to the recording quality is set to the recording power of the jitter of 12%. Thus, the required recording power can be reduced even at a high speed.
[0046]
As described above, in the case where the recording speed is prioritized over the recording quality, a method requiring a small recording power is advantageous for high-speed recording.
[0047]
Here, an embodiment showing one feature of the present invention will be described in detail with reference to FIG. 1 and FIGS. During normal camera recording, as shown in FIG. 6, an image signal processing means 5 for converting an image signal photographed by the photographing means 1 of FIG. 1 and an audio signal recorded by the microphone 18 into image data and audio data. The video / audio signal is compressed and supplied as shooting information 31 as a buffer input 32 of the buffer memory 7. On the other hand, the recording / reproducing unit 22 loaded with the optical disk 9 drives the optical disk 9 at a sufficiently high recording transfer rate for recording a real-time video captured by the camera unit 21 in general.
[0048]
In particular, when a state in which stable recording cannot be performed due to large vibrations or the like occurs in a portable device, it is necessary to record the same information again at the same location or a different location on the optical disc 9. The buffer memory 7 has a sufficiently large capacity, and the recording transfer rate on the optical disk 9 is set higher than the transfer rate of the photographing information 31 serving as the input signal.
[0049]
However, the recording transfer rate on the optical disk 9 can be set high, but if the recording transfer rate is set high, as will be described in detail later, the required recording power increases, and in the case of a small device, in FIG. Double is shown as an example. That is, the buffer output 33 from the buffer memory 7 is intermittently read at a data rate about twice that of the buffer input 32, and this information is recorded on the optical disk 9.
[0050]
At this time, the recording ON (t1on) / OFF (t1off) state of the medium recording 34 is about 1/2 period as shown in FIG. By intermittently performing the recording operation in this manner, most of the operation of the recording / reproducing unit 22 may be stopped for a long time in the OFF (t1off) period, and the power consumption is reduced by stopping the operation. The effect that it can be obtained can be obtained.
[0051]
In addition, the temperature rise of the device can be suppressed by the reduced power consumption. The recording at this time can improve the data reliability at the time of recording by using the above-described multi-pulse recording waveform. However, since the required recording power becomes large, the above-mentioned intermittent recording is desirable in order to reduce power consumption and temperature rise. During the intermittent recording, the temperature sensor 15 keeps monitoring the temperature rise of the optical head by the temperature check 35 shown in FIG. 6, and if the temperature rises above the threshold temperature, it is determined that the recording power is insufficient. The power calibration operation 36 is performed when the intermittent recording is turned off.
[0052]
As a result, recording can always be performed with the optimum recording power, and the data reliability of the recorded data can be improved. The power calibration may be performed by seeking the actual power calibration area PCA, sifting the recording power to determine the optimum recording power, or tabulating the temperature and the required power in advance, and setting the table value at the time of the threshold temperature. May be reflected. In this case, since it is not necessary to perform operations such as seeking to the power calibration area PCA and swinging the recording power, the time is short, and the duty of the intermittent recording accompanying the power calibration is not reduced.
[0053]
The method of obtaining the actual recording power in the power calibration area and the method of reflecting the table value may be appropriately combined according to the temperature threshold.
[0054]
On the other hand, recording on the optical disk 9 in the finalizing process is not necessary for real-time recording unlike the camera recording. That is, there is no particular limitation on the recording transfer rate at the apparatus. In particular, regarding the recording in the above-mentioned lead-out area LOA, it is desired to perform high-speed recording and perform recording processing in as short a time as possible. Further, since the lead-out area may have a small recording (about 1 mm in radius difference) depending on the DVD player of the user, only the recording amount of the lead-out area selected by the user from the operation SW is recorded before starting the finalizing process. .
[0055]
This value may be divided into several stages, and the largest amount is a value conforming to the standard. However, as described above, the recording quality of the lead-out area LOA is not required to be so high. Therefore, continuous recording is performed at a low power and at a high speed, and a high-speed readout area is recorded without causing a temperature rise. At this time, as shown in FIG. 7A, when the start of the finalizing process is received by an input from the operation SW 20, the system control unit 17 sends the finalizing process of FIG. After the process of FIG. 4 is performed and a predetermined lower recording power is set after 41 shown in FIG. Record continuously as shown in FIG.
[0056]
However, in this case, since the recording is continuous, there is a possibility that the recording is performed without knowing that the recording power is insufficient due to the temperature rise. To eliminate this inconvenience, as shown in FIG. 7 (2), when the temperature exceeds the threshold temperature while performing the temperature check 54, it is determined that the recording power is insufficient, and the recording of the lead-out area is temporarily stopped. Thereafter, after performing the power calibration 55, the lead-out area may be recorded again. As a result, recording can always be performed with the optimum recording power, and data reliability in the lead-out area can be improved. The power calibration may be performed by seeking the actual power calibration area PCA, sifting the recording power to determine the optimum recording power, or tabulating the temperature and the required power in advance, and setting the table value at the time of the threshold temperature. May be reflected.
[0057]
In this case, since it is not necessary to perform operations such as seeking to the power calibration area PCA and swinging the recording power, the time is short, and there is almost no increase in the recording time accompanying the power calibration. The method of obtaining the actual recording power in the power calibration area and the method of reflecting the table value may be appropriately combined according to the temperature threshold.
[0058]
If the temperature rises above the drive allowable temperature as a result of the temperature check, the temperature is reported to the user, and the recording of the lead-out recording area is interrupted or terminated. Even if the recording is completed, the recording speed of the lead-out area is about 1.3 times or more since the recording can be performed about 1.3 times to 1.5 times with the same recording power as shown in FIG. It is good to set to. Therefore, since the recording in the data recording area is intermittent recording with a recording duty of 50%, the recording in the lead-out area can be made 2.6 times or more.
[0059]
At least, since the lead-out area is not in the recording state of the photographing information, even a slight high-speed rotation does not cause a problem with respect to noise and vibration caused by the high-speed rotation of the optical disc 9.
The recording of the lead-out area is basically performed continuously, but is not limited to this. The recording may be performed while the recording operation is temporarily interrupted by the temperature of the temperature sensor 15 described above.
[0060]
The above embodiment is applied to a portable camera-integrated recording device provided with a finalization processing device, but is not limited thereto, and a disk recording device provided with a finalization processing device is applied to a portable information processing device. Alternatively, a monitor device that displays a reproduction signal from the recording device may be applied to a portable monitor-integrated video reproduction device.
[0061]
【The invention's effect】
As is apparent from the above description, the present invention enables a high-speed finalizing operation particularly when the present recording apparatus is used in a small portable device. Specifically, the amount of lead-out recording data in the finalizing operation can be changed by the user, and intermittent recording operation is performed for recording in the data recording area where recording quality is prioritized. The recording of the lead-out area, which does not require quality, can be performed at high speed and continuously at a power lower than the appropriate power, thereby shortening the time required for the finalizing process. Thus, high-speed finalization processing can be performed.
[0062]
In addition, by providing a temperature sensor in the apparatus, there is an effect that the recording power is corrected when the temperature rises and the recording quality is compensated.
Further, when the temperature of the recording device exceeds a predetermined range, camera recording and finalization processing are temporarily stopped, and the erroneous recording operation can be avoided by reducing the power consumption of the device and suppressing the temperature rise.
[0063]
Furthermore, by applying these disk recording devices to a camera-integrated recording device, a portable information processing device, and a monitor-integrated device, there is an effect that it is possible to provide various types of disk recording device-integrated devices that guarantee stable operation.
