  The present invention relates to a recording / reproducing apparatus including an optical disk drive directly connected to a personal computer, an optical disk drive connected via a network, and a multi-connected optical disk drive.

Conventionally, there has been the following recording / reproducing apparatus.
(1) When data is recorded / reproduced with respect to a disk to be loaded using an optical pickup, when the predetermined disk is loaded, the eccentricity of the disk viewed from the optical pickup is recognized by the DSP microcomputer, and the DSP A recording / reproducing apparatus that outputs a recognition result to a front panel block based on the amount of eccentricity recognized by a microcomputer (see, for example, Patent Document 1).

However, in the conventional recording / reproducing apparatus, when the recording on the optical disk is damaged, the user cannot distinguish whether the recording has failed due to the problem of the optical disk itself or the optical disk drive has failed. There was a problem that it could not be determined whether the problem could be solved by replacing the optical disk or whether the optical disk drive itself should be replaced.
In order to solve this problem, in the recording / reproducing apparatus (1) described above, the cause of the optical disk is determined by self-diagnosis and automatic measurement of the eccentricity of the optical disk.
However, in such a recording / reproducing apparatus, a means for measuring the amount of eccentricity of the optical disc must be added to the apparatus, which makes it difficult to reduce the size of the apparatus and increases the cost.

Next, when recording fails due to a problem with the optical disc itself, there is a problem that it takes time and effort for the user to register recording data and set recording conditions again in order to re-record data.
Although it corresponds to a data transfer error called buffer underrun, in order to solve the problem, the recording / reproducing apparatus of (2) above is not recorded on an optical disc that has stopped recording due to buffer underrun. By automatically re-recording in this area, it is possible to save the user from having to register recording data and set recording conditions again.
However, such a recording / reproducing apparatus has a problem that it is necessary to re-record on a new optical disk when the amount of recorded data exceeds the capacity of an unrecorded area.

Next, when an optical disk drive fails, there is a problem that recording cannot be performed until the optical disk drive is replaced.
For example, since the recording / reproducing apparatus (4) is a multi-series optical disk drive apparatus having a plurality of optical disk drives, other optical disk drives that are operating normally even if one optical disk drive fails If selected, information can be recorded.
However, in such a recording / reproducing apparatus, since it is impossible to determine which optical disk drive is operating normally and in standby, an optical disk drive that operates normally when one optical disk drive fails is selected. There was a problem that data could not be recorded automatically.

Next, as shown in FIG. 12, in the conventional multiple optical disk drive device 50, data from the PC 51 is recorded by the control processing of the control unit 53 by the multiple optical disk drive 52 including a plurality of optical disk drives. Since the recorded optical disc is ejected to a common location, there is a problem that it is not possible to easily distinguish whether the ejected optical disc is an optical disc that has failed in data recording or a successful optical disc.
Next, there is a possibility that even an optical disk that has failed in data recording can be partially reproduced, and thus information is leaked if it is discarded as it is.
The present invention has been made in view of the above points so that it can be accurately determined whether the failure of data recording on the recording medium is due to an abnormality of the recording medium or an abnormality due to a failure of the recording / reproducing apparatus. The purpose is to do.

[Example 1]
As shown in FIG. 1, an optical disc drive apparatus 1 of Embodiment 1 of the recording / reproducing apparatus of the present invention comprises an optical disc drive 2, a personal computer (PC) 3, and a display device 4.
The optical disk drive 2 records and reproduces data with respect to the optical disk (recording medium) 11 and is connected to the PC 3 through an interface (I / F) 5 so that data can be exchanged.
The PC 3 includes a CRT 6, a CPU 7, a RAM 8, a hard disk device (HDD) 9, and a USB hub 10. The CRT 6 plays an operation screen on the PC 3, various processing results, data to be recorded on the optical disk 11 of the optical disk drive 2, and playback from the optical disk 11. It is a display device that displays various data including the processed data.

The CPU 7 controls the entire PC 3 and executes control processing according to the present invention.
The RAM 8 and HDD 9 store data to be recorded on the optical disc 11 or data reproduced from the optical disc 11 and status information of the optical disc drive 2.
The USB hub 10 is an interface for connecting to the I / F 5 of the optical disc drive 2 so that data can be exchanged.
The display device 4 displays the operation state of the optical disc drive 2 under the control of the CPU 7.
In other words, the optical disk drive 2 functions as a recording / reproducing means for recording and reproducing data on a recording medium.
Further, the RAM 8 and the HDD 9 determine whether the data recorded on the recording medium or the data reproduced from the recording medium, the recognition information of the first recognition means and the second recognition means, and the determination result of the determination means It fulfills the function of state information storage means for storing state information consisting of information.

Further, the CPU 7 controls the writing and reading of data with respect to the storage means, the writing and reading of data recording with respect to the recording / reproducing means, and the reading / reproducing of data, and the recording / reproducing means is recording data on the recording medium. First recognition means for recognizing and recognizing whether the data is in a standby state or second recognition for recognizing by recognizing whether recording of data on the recording medium by the recording / reproducing means is normal or abnormal Based on the recognition information indicating the recognition results of the means and the first recognition means and the second recognition means, whether the recording medium is causing the abnormality in the recording of the data on the recording medium or the failure of the recording / reproducing means It functions as a determination means for determining whether or not, and a status information reproducing means for reproducing status information from the status information storage means.
Furthermore, the CPU 7 and the display device 4 function as display means for displaying the operating state of the recording / reproducing means based on the state information reproduced by the state information reproducing means.

Next, data recording and reproduction processing by the optical disc drive apparatus 1 will be described.
The CPU 7 of the PC 3 sends the data to be recorded on the optical disk of the RAM 27 or the HDD 28 to the optical disk drive 2 by the data recording command, and the optical disk drive 2 writes the data on the optical disk 11 and records it.
Further, in response to the data reproduction command, the data is read from the optical disk 11 by the optical disk drive 2 and stored in the RAM 27 or the HDD 28, and the data is displayed on the CRT 6.

Next, a process for displaying the operation state of the optical disc drive 2 by the optical disc drive apparatus 1 will be described.
The CPU 7 of the PC 3 determines and recognizes whether the optical disk drive 2 is recording data on the optical disk 11 or is in a standby state. For example, when a data recording command is instructed from the PC 3 side to the optical disc drive 2 via the USB hub 10, it is determined that the optical disc drive 2 is recording data, and the data recording command is instructed to the optical disc drive 2. If not, it is determined that the optical disk drive 2 is in a standby state.
Next, the CPU 7 determines and recognizes whether data recording on the optical disk 11 is normal or abnormal. For example, based on the result of self-diagnosis processing performed during standby before data recording from the optical disk drive 2 via the USB hub 10, data recording to the optical disk 11 is performed based on status information returned from the optical disk drive 2 during data recording. It recognizes by judging whether it is normal or abnormal.

  Table 1 is a table showing processing steps at the time of data recording on an optical disc, for example, a CD-R disc and a CD-RW disc in the optical disc drive apparatus, and an explanation of operations in each step. Table 2 is a table showing the cause of the abnormality and the explanation of the abnormal phenomenon in each processing step shown in Table 1.

The data recording operation for the CD-R disc and the CD-RW disc in the optical disc drive apparatus 1 is roughly divided into “(S1) optical disc insertion”, “(S2) optical disc recognition” and “(S3) trial” shown in Table 1. The process consists of seven steps: “recording”, “(S4) moving the optical head to the recording start position”, “(S5) data recording”, “(S6) finalizing”, and “(S7) ejecting the optical disk”.
Table 2 shows the causes of abnormalities and the abnormal phenomena that are generally common among cases where abnormalities occur in the above seven processing steps.
In Table 2, the abnormalities caused by the eccentricity of the optical disk and the accompanying focus and track errors are well known and will not be described (for example, see Patent Document 1).

Next, the CPU 7 determines whether the cause of the abnormality in the data recording on the optical disk 11 is the optical disk 11 or the failure of the optical disk drive 2 based on the recognition information indicating each recognition result.
For example, in “Description of Cause of Abnormality and Abnormal Phenomenon” in Table 2, “(2) Optical Disc Recognition Error” and “(5) Data Recording Error” have both optical disc and optical disc drive causes. There is something.
With regard to (2), it is possible to determine whether the cause is in the optical disk or the optical disk drive by performing a self-diagnosis process on the light quantity of the laser diode (LD) as the light source while the optical disk drive is on standby. it can.

In general, the self-diagnosis process of the LD light quantity is checked when the optical disk drive 2 is powered on. If the self-diagnosis processing result is normal, it may be determined that the error is caused by the optical disk 11.
That is, if the result of the self-diagnosis process of the optical disc drive 2 is normal, the CPU 7 determines that the cause of the abnormality in data recording on the optical disc 11 is in the optical disc 11. If the result of the self-diagnosis process is abnormal, it is determined that the cause of the abnormality in recording data on the optical disk 11 is the failure of the optical disk drive 2.
Since the cause of the decrease in the amount of light of the LD is known, the description thereof is omitted (for example, see Patent Document 3).

Regarding (5) above, by monitoring data transfer during data recording, if there is no error in the transfer, it may be determined that the cause of the error is due to the optical disk.
That is, if there is no data transfer error, the CPU 7 determines that the cause of the abnormality in the data recording on the optical disc 11 is the optical disc 11. If there is a data transfer error, it is determined that the failure of the optical disk drive 2 is the cause of the abnormality in data recording on the optical disk 11.
Since transfer errors are publicly known, explanations thereof are omitted (for example, see Patent Document 2).

  As described above, information indicating whether the optical disk drive 2 is recording or waiting, and status information returned from the optical disk drive device 1 to the PC 3 (for example, a normal / abnormal response result to the self-diagnosis process, data transfer By combining the normal / abnormal response result and the normal / abnormal response result for the command command for executing each operation process of data recording shown in Table 1, the cause of the abnormality shown in Table 2 can be classified into cases. It is possible to determine whether there is a recording abnormality due to the optical disk 11 or a recording abnormality due to a failure of the optical disk drive 2.

Next, the CPU 7 stores and holds the state information including the recognition information recognized in the above process and the determination information indicating the determination result of the above determination process in, for example, the state information storage area of the RAM 8 or the HDD 9 illustrated in FIG. To do.
Next, the CPU 7 reproduces the status information from the RAM 8 or the HDD 9.
Next, the CPU 7 displays the operation state of the optical disc drive 2 on the display device 4 based on the reproduced state information.
Regarding the display of the operation state, when the cause of the abnormality in the data recording on the optical disk 11 is in the optical disk 11, as shown in FIG. 2, an LED indicating the recording abnormality in the optical disk drive (ODU) column is displayed. If the optical disk drive 2 is turned on (in this case, the LED indicating failure is extinguished) and the cause of the abnormality in data recording on the optical disk 11 is in the optical disk drive (ODU) column, as shown in FIG. The LED indicating the malfunction is turned on (in this case, the LED indicating the recording abnormality is turned off).

In this way, the user can know whether the abnormality is caused by the optical disk 11 or the abnormality caused by the failure of the optical disk drive itself, depending on the display content of the display device 4, so that the user can re-record with a new optical disk. You can determine if the drive should be repaired.
The optical disk drive device according to the first embodiment automatically determines whether the recording has failed due to a problem with the optical disk itself or the recording has failed due to a failure of the optical disk drive when the data recording on the optical disk is damaged. Since the determination result is displayed on the display device, the user can easily know whether the cause of the data recording failure is in the optical disk or in the optical disk drive, and whether the recording should be performed again with a new optical disk. It is possible to accurately determine whether the problem can be solved by exchanging.

The multi-continuous optical disk drive system according to Embodiment 10 of the recording / reproducing apparatus of the present invention is another example in which some of the configurations and functions of the multi-serial optical disk drive system according to Embodiments 2 to 8 described above are combined.
In this multi-connected optical disk drive system, the status information of the optical disk drive is notified to the PC that commanded the data recording on the network, and if there is a failure in the optical disk drive, the maintenance is performed based on the instruction from the PC user. If the service automatically asks for repair and the data recording fails due to a problem with the optical disc itself, it will be replaced with a new optical disc and the data will be automatically re-recorded. Destroy.

Next, the process of this multiple optical disc drive apparatus will be described, but the description of the same process as in Examples 2 to 8 will be omitted.
First, in order to automatically perform recording again, a storage area for holding data to be recorded for each of a plurality of optical disk drives is required. Therefore, as shown in FIGS. 5 and 6, the storage area of the HDD 28 is divided and arranged in areas (Area) of 1 to N (N is an integer of 2 or more) corresponding to each optical disk drive of the multiple optical disk drive 23. The data to be recorded in each area is recorded.

  When the CPU / MPU 26 reproduces the state information from the nonvolatile memory 31 or the HDD 28, the state information is transmitted to the PC 21 that has instructed recording of the data on the network 22 via the network 22 to notify the data. The user who instructed the recording is inquired about selection of whether or not to request a maintenance request from the maintenance service via the network 22.

  As for the inquiry, for example, selection information for requesting a repair request is transmitted to the PC 21 together with the notification of the status information, and the selection result from the PC 21 is transmitted to the CPU / MPU 26 of the multi-disc optical disk drive device 20. You should be able to receive it. When a request for repair is selected for the maintenance service based on the selection result, the CPU / MPU 26 automatically notifies the PC in charge of maintenance through the network 22 of the repair request.

  Further, when the CPU / MPU 26 determines in the optical disk drive connected to the network that the abnormality has occurred in the recording of data on the optical disk by the above determination, the optical disk of the optical disk drive connected to the network is determined. After recognizing that the optical disk has been replaced with a new optical disk, data is read again from the corresponding storage area of the HDD 28 that is dividedly arranged with respect to the optical disk drive connected to the network, and the new optical disk drive connected to the network Data recording on a new optical disc.

Next, when an abnormality is detected in the data recording on the optical disk based on the reproduced status information, the CPU / MPU 26 selects the optical disk in which the abnormality is detected in the data recording based on the reproduced order information. Then, the data recording surface of the optical disk is scratched and destroyed by the optical disk destroyer 41 and ejected.
For example, as shown in FIG. 10, the recording layer is formed so that data cannot be reproduced by causing radial scratches on the data recording surface of the optical disc or by causing lattice scratches on the data recording surface of the optical disc as shown in FIG. Destroy and discharge.

  In the multi-continuous optical disk drive system according to the tenth embodiment, when an injury occurs in recording on the optical disk, it is automatically determined whether the recording has failed due to a problem with the optical disk itself or the optical disk drive has failed. When data recording fails due to a failure of the optical disk drive of the drive, the user's PC that commanded data recording is notified via the network, and if there is a selection instruction from that user, the PC in charge of maintenance is immediately repaired. Since the request is notified, when an abnormal recording occurs due to the failure of the optical disk drive, the user can save the trouble of requesting the repair of the multi-connected optical disk drive apparatus.

In addition, when recording fails due to a problem with the optical disc itself, data recording is performed again on a new optical disc, thereby eliminating the need for the user to individually perform data recording. Further, since the data recording surface is scratched and ejected from the optical disc in which the data recording abnormality is detected, information is not leaked even if the optical disc that has failed in data recording is discarded as it is.
Therefore, even if the recording on the optical disk fails, the user can always perform normal recording without giving the user any troublesome burden.
