Then, the recording disk D with no problem in recording quality, the recording disk D on which data has been re-recorded, and the new recorded recording disk D on which the data has been saved are accommodated in the additional stacker 57. The third stacker 50 is used as a discard stacker that accommodates the recording disk D that is determined to have poor recording quality and is discarded.

  The host-side control unit 80 of the host computer 2 first transports the recording disk D from the first stacker 41 to the disk tray 22 of the optical disc drive 20 by the transport device 60 by the function of the quality judgment unit 91 and records by the optical disc drive 20. The data recorded on the disk D is read, the read signal is acquired via the interface units 87 and 84, and the recording quality is measured (step S11). In step S11, the quality determination unit 91 reads all data recorded on the recording disc D by the optical disc drive 20, stores the read signal in the storage unit 83, and also includes jitter errors and C1 errors in the read signal. , Count C2 errors.

  During this reading, the quality determination unit 91 monitors whether or not the optical disc drive 20 becomes unable to read the recording disc D (step S12). When the reading operation by the optical disk drive 20 cannot be continued due to scratches, contamination, deterioration, etc. of the recording disk D (step S12; Yes), the quality determination unit 91 determines that the recording quality of the recording disk D is poor, and subsequently recording. The optical disk drive 20 is controlled by the function of the control unit 92, and the area of the recording disk D where the TOC is recorded is irradiated with laser light for recording or higher output to destroy the TOC (step S13). The TOC (Table of Contents) is an index necessary for reading data recorded on the recording disk D. Data can be read from the recording disk D in which the TOC is destroyed even if the recording area of the data itself is intact. It becomes extremely difficult.

  Subsequently, the transport device 60 is controlled by the function of the print control unit 93, the recording disk D is transported from the disk tray 22 to the printing device 30, and is printed on the label surface of the recording disk D by the printing device 30. In this step, for example, characters such as “unreadable”, “invalid”, “Invalid”, and symbols or images such as “x” are printed on the label surface of the recording disk D. Thereafter, the transport device 60 is controlled by the function of the print control unit 93, and the recording disk D after printing is transported from the disk tray 32 of the printing device 30 to the third stacker 50 (step S14), and this process ends. If an unprocessed recorded recording disk D remains in the first stacker 41, the process is repeated from step S11.

  When reading of all data on the recording disk D is completed by the optical disk drive 20 (step S12; No), the host-side control unit 80 determines whether the detected error is equal to or greater than the threshold value by the function of the quality determination unit 91. It is determined whether or not (step S15). When it is determined by the function of the quality determination unit 91 that the detected error does not reach the threshold value (step S15; No), it is determined that there is no problem in the recording quality of the recording disk D (step S16), and the conveyance is performed. The apparatus 60 is controlled, and the recording disk D is transported from the disk tray 22 to the designated extension stacker 57 (step S17), and this process ends.

On the other hand, when it is determined that the error detected by the function of the quality determination unit 91 is greater than or equal to the threshold (step S15; Yes), the recording control unit 92 rewrites whether the type of the recording disk D is a write-once type recording medium. It is determined whether the recording medium is of a type (step S18). This determination may be performed, for example, while reading data in step S11 or when the optical disc drive 20 loads the recording disc D prior to reading the data.
When the recording disk D is a write-once type (step S18; Yes), the recordable capacity of the free area of the recording disk D records all the data read from the recording disk D by the function of the recording control unit 92. Is sufficient (step S19). When the recordable capacity is sufficient (step S19; Yes), the data read from the recording disk D in step S11 is written back to the recording disk D by the optical disk drive 20 by the recording control unit 92 (step S20). . Further, the data of the area written back by the optical disc drive 20 is read again by the function of the quality determination unit 91, and the recording quality of the written back area is measured (step S21). Here, it is determined whether or not the error detected from the read signal is equal to or greater than the threshold value stored in the storage unit 83 (step S22). If the error does not reach the threshold value (step S22; No) ), The transport device 60 is controlled by the function of the print controller 93, and the recording disk D is transported from the disk tray 22 to the disk tray 32 of the printing device 30, and the printing device 30 applies data protection to the label surface of the recording disk D. The history is printed (step S23). Here, the reading quality of the recording disk D is poor, the data is saved in the empty area, and characters, symbols or images indicating that the recording quality of the saved data is good are printed on the label surface. Thereafter, the transport device 60 is controlled by the function of the print control unit 93, the recording disk D is transported from the disk tray 32 to the additional stacker 57, and this process ends.

  Further, when there is not a sufficient recordable capacity in the free area of the recording disk D (step S19; No), and when the recording quality of the data written back in the free area of the recording disk D is poor (step S22). ; Yes), the transport device 60 is controlled by the function of the recording control unit 92, the new recording disk D is transported from the first stacker 41 to the disk tray 22, and the data read from the recording disk D in step S11. Is recorded on the new recording disk D (step S25). Subsequently, the recording disk D is conveyed from the disk tray 22 to the disk tray 32, and a data protection history is printed on the label surface of the recording disk D by the printing apparatus 30 (step S26). Here, the reading quality of the recording disk D is poor, and characters, symbols or images indicating that the data has been saved on the new recording disk D are printed on the label surface. Thereafter, the transport device 60 is controlled by the function of the print controller 93, and a new recording disk D is transported from the disk tray 32 to the additional stacker 57 (step S27). Further, the TOC is destroyed by the laser beam by the optical disc drive 20 with respect to the recording disc D from which the data has been read (step S28). The recording disk D is transported to the printing apparatus 30 under the control of the printing control unit 93, and characters, symbols or images indicating that the recording disk D is unnecessary and cannot be read are printed, and the third stacker 50 for disposal is printed. (Step S29), and this process is terminated.

On the other hand, when the recording disk D is not a write-once type but a rewritable type (step S18; No), the data read in step S11 is rewritten to the recording disk D by the function of the recording control unit 92 (step S18). S30). This writing is so-called overwriting in which data that has already been written is erased. Thereafter, the recording quality of the rewritten area of the recording disk D is measured under the control of the quality determination unit 91 (step S31). Here, it is determined whether or not the error detected from the read signal is equal to or greater than the threshold value stored in the storage unit 83 (step S32). If the error does not reach the threshold value (step 332; No) ), The transport device 60 is controlled, and the recording disk D is transported from the disk tray 22 to the additional stacker 57 (step S33), and this process is terminated.
If the recording quality of the data rewritten on the recording disk D is poor (step S32; Yes), the transport device 60 is controlled by the function of the recording control unit 92, and the new recording disk D is inserted into the first stacker. The data conveyed from 41 to the disk tray 22 and read from the recording disk D in step S11 is recorded on the new recording disk D (step S34). Subsequently, the recording disk D is transported from the disk tray 22 to the disk tray 32, and a data protection history is printed on the label surface of the recording disk D by the printing device 30 as in steps S23 and S26 (step S35). ). Thereafter, the transport device 60 is controlled by the function of the print controller 93, and a new recording disk D is transported from the disk tray 32 to the additional stacker 57 (step S36). Further, the data is erased from the rewritable recording disk D from which the data has been read out by the optical disk drive 20 (step S37), and is transferred to the printing apparatus 30 under the control of the print control unit 93, and unnecessary recording is performed. Characters, symbols or images indicating the disc D are printed and conveyed to the third stacker 50 for disposal (step S38), and this process is terminated.

  As described above, the host computer 2 according to the present embodiment includes the optical disc drive 20 that records data on the recording disc D, the optical disc drive 20 that reads data recorded on the recording disc D, and the reading state by the optical disc drive 20. Based on the quality determination unit 91 for determining whether the recording quality of the recording disk D is good or not, and when the quality determination unit 91 determines that the recording quality of the recording disk D is poor, it is recorded on the recording disk D. A recording control unit 92 that records the recorded data on the recording disk D itself or another recording disk D by the optical disk drive 20, and determines whether the recording quality of the recording disk D is good or not. Indicates the data recorded on the recording disk D, the free space of the recording disk D, or It is recorded on the recording disc D. Thereby, determination of the recording quality of the recording disk D and data protection when the recording quality is poor can be easily and quickly performed. Further, when data is saved in the free area of the recording disk D, the new recording disk D is not consumed, so that data can be protected and resources can be saved. Furthermore, it is of course possible to save data to a new recording disk D regardless of the free space capacity of the recording disk D in the operation shown in the above flowchart, and the degree of freedom of the data protection method can be increased.

In the disk issuing system 3, the recordable capacity of the free area of the recording disk D determined by the recording control unit 92 as having poor recording quality is based on the amount of data recorded on the recording disk D. It is determined whether data is to be saved on the recording disk D itself or recorded on another recording disk D. If the recordable capacity of the recording disk D is sufficient, the recordable capacity can be utilized to protect the data. Therefore, data can be protected while saving resources.
In addition, since it is automatically determined whether or not to use the recording disk D itself whose recording quality is determined to be poor, both data protection and resource saving can be achieved with a small work load.
Furthermore, when data is recorded on a new recording disk D by the optical disk drive 20 under the control of the recording control unit 92, the TOC, which is index information for reading the data recorded on the recording disk D, is destroyed and read. Since it is impossible, data leakage or the like when the recording disk D is discarded can be reliably prevented. As a result, it is possible to easily determine the recording quality of the recording disk D and save the data, and to reduce the management burden of the recording disk D having a poor recording quality.

When data recorded on the recording disk D is recorded on a new recording disk D by the optical disk drive 20 by the print control unit 93 of the disk issuing system 3, the label surface as a printing area of the new recording disk D is displayed. Since the history and the like are printed, the history of the newly created recording disk D can be described on the recording disk D itself, and the burden required for managing the recording disk D can be reduced.
Further, since characters, symbols or images that clearly indicate that the recording disk D is unnecessary are printed on the recording disk D that is no longer needed, misuse can be avoided. Thereby, it is possible to easily determine the recording quality of the recording disk D and save the data, and to reduce the management burden of the defective recording disk D.

When the recording disk D determined to have poor recording quality by the quality determination unit 91 is a rewritable recording disk D, the disk issuing system 3 uses the recording control unit 92 to transfer data to the recording disk D. Since data is rewritten and reused and data is saved, it is possible to take advantage of the characteristics of the rewritable recording medium to achieve both data protection and resource saving with a small work load.
Further, when the data recorded on the rewritable recording disk D is rewritten on the same recording disk D by the recording control unit 92, it is determined whether the recording quality of the recording disk D after the recording is good or not. If it is determined to be defective, the data recorded on the recording disk D is recorded on the new recording disk D. Therefore, the characteristics of the rewritable recording medium are utilized to achieve both data protection and resource saving. And data can be reliably protected.

It is of course possible to perform a recording quality determination process by providing a function corresponding to the above and a storage unit for temporarily storing data read from the recording disk D. In this case, the recording quality determination process can be executed only by the disk issuing device 1 without connecting to the host computer 2.
