Reference numeral 705 denotes the total free capacity of the optical disk 108 stored in the data library apparatus 101.

The determination of which data should be recorded in the data library apparatus 101 is performed using a program recorded in the memory 302 of the server 115. For the determination, for example, it is conceivable to use a criterion such as data that has not been requested for reproduction for a certain period or longer. If there is no data to be recorded as a result of the investigation (N in the figure), the investigation in step S1001 is repeated as appropriate. If there is data to be recorded (Y in the figure), the process of the next step S1002 is performed.

In step S1002, the device selection unit 308 of the server 115 refers to the optical disc storage device management table 700, the data management table 800, and the optical disc management table 900 for the data selected in step S1001, and records the data.

A method of selecting a certain optical disk 108 can be considered.
At this time, if there is no optical disk storage device 107 having the same group ID (702) as the data group ID (802), or if there is no free space for storing the data in the optical disk storage device 107, a new one is newly created. It is necessary to load the data library apparatus 101 with the optical disk storage device 107 storing unrecorded optical disks. This will be described later with reference to FIG. If the optical disk storage device 107 selected in step S1002 is not stored in the data library device 101, it is necessary to store the optical disk storage device 107 in the data library device 101. This will be described in steps S1003 and S1004.

In step S1003, if the CPU 301 determines that the optical disk storage device 107 needs to be replaced (Y in the figure), the process of step S1004 is performed. If it is determined that replacement is not necessary (N in the figure), step S1005 is performed. Perform the process.
Step S1004 is a replacement process of the optical disk storage device 107, and will be described with reference to FIGS.
FIG. 11 is a processing flow executed by the server 115 when the optical disk storage device 107 is removed from the data library device 101.

In step S1101, the CPU 301 of the server 115 receives an optical disk storage device removal instruction from the user. At this time, for example, the user instructs which optical library storage device 107 of which data library device 101 connected to the server 115 is to be removed via the user I / F unit 309 of the server 115. Before step S1101, the server 115 determines which optical disk storage device 107 of which data library device 101 is removed from the display device 118 and which optical disk storage device 107 needs to be loaded. It may be displayed to the user.
In step S1102, the CPU 301 analyzes the contents of the command received in step S1101, and determines which command is issued to which data library device 101.

In step S1103, the CPU 301 determines whether or not the designated optical disk storage device 107 is removable in the data library device 101 that is the instruction issue destination determined in step S1002. If the removal is possible (Y in the figure), the process proceeds to step S1104. If the removal is impossible (N in the figure), the determination in step S1103 is repeated until the removal is possible. Note that several methods are conceivable for determining whether or not the removal is possible in step S1103. For example, it is assumed that the data library apparatus 101 includes two optical disk storage apparatuses 107, that is, an optical disk storage apparatus A and an optical disk storage apparatus B. If the optical disk 108 stored in the optical disk storage device A is taken out and an instruction to remove the optical disk storage device A is received when the data recording / reproducing device 109 is executing data recording, the process being executed is completed. It is better not to remove it unless it is confirmed. This is because if the optical disk storage device A is removed before the processing is completed, the optical disk 108 on which data recording is being performed by the data recording / reproducing device 109 cannot be stored at the original position. On the other hand, even if the optical disk 108 is taken out from the optical disk storage device A and the process is being executed, if the optical disk is not taken out from the other optical disk storage device B, the optical disk storage device B is removed. You may make it do. This is only an example, and more detailed condition determination may be performed.
In step S1104, an instruction to prepare for removing the optical disk storage device 107 is issued to the data library apparatus 101 to which the instruction is issued.

Step S1105 is a process executed when the data library apparatus 101 receives a removal preparation instruction for the optical disk storage apparatus 107 from the server 115, and will be described with reference to FIG.
FIG. 12 is a flowchart of the removal process of the optical disk storage device 107 in the data library apparatus 101.

  In step S <b> 1201, the CPU 102 of the data library apparatus 101 receives an optical disk storage device removal preparation command from the server 115. In response to the instruction, the data library apparatus 101 executes a predetermined process for removing the optical disk storage apparatus 107. Note that the command may include, for example, information indicating the reason for removing the optical disk storage device 107, or information indicating which to remove when there are a plurality of optical disk storage devices 107 provided in the data library device 101. good. If these pieces of information are transmitted from the server 115, the data library apparatus 101 can perform more detailed control.

In step S1202, the CPU 102 performs control such as lighting the information display unit 104 in a predetermined color. This is because, for example, when there are a plurality of optical disk storage devices 107, it indicates which optical disk storage device 107 is to be removed. The data library apparatus 101 includes two optical disk storage apparatuses 107, that is, an optical disk storage apparatus A and an optical disk storage apparatus B. When a server 115 issues an instruction to remove the optical disk storage apparatus A, an information display unit corresponding to the optical disk storage apparatus A For example, the optical disk storage device A is in a removable state by changing 104 to a lighting state from green to orange, for example.
In step S1203, the CPU 102 notifies the server 115 that a series of processing relating to the command received in step S1201 has been completed.

  Returning to FIG. 11, in step S1106, the CPU 301 of the server 115 waits for a processing completion notification from the data library apparatus 101. When the completion notification arrives (Y in the figure), the processing ends. If the completion notification has not arrived (N in the figure), the process of step S1106 is repeated until it arrives. Although not shown here, a step for confirming whether or not the processing has been performed correctly may be provided, and if the processing has not been performed correctly, the command in step S1104 may be issued again.

  Here, it is assumed that the work of actually removing the optical disk storage device 107 from the data library device 101 is performed manually by the worker. That is, in step S1202, the information display unit 104 of the data library apparatus 101 indicates that preparation for removal is complete, and an operator who sees the display performs the removal work. Of course, it is possible to automate the removal, in which case, for example, a removal instruction is issued after step S1106, the data library apparatus 101 unlocks the door 1011 of the data library apparatus 107, and the optical disk storage apparatus Steps such as executing the removal process 107 are executed.

  Although an example in which the optical disk storage device 107 is removed from the user via the server 115 is shown here, a worker near the data library device 101 may request removal. In this case, for example, the operator performs an operation for requesting removal from the user I / F unit 103 of the data library apparatus 101. Specifically, a predetermined button is pressed. When the data library device 101 detects that the button has been pressed, it notifies the server 115 that, for example, an operation to remove the optical disk storage device B has been performed, and whether or not the server 115 permits the removal. After confirming that the disk is in a removable state if it is permitted, an optical disk storage device is issued by issuing a removal preparation instruction (equivalent to step S1104) of the optical disk storage device 107 to the data library device 101. 107 is removed.

  FIG. 13 shows a basic processing flow executed by the data library device 101 when the optical disk storage device 107 is attached to the data library device 101. Here, an example is shown in which only one optical disk storage device 107 is attached, but this is only an example, and a plurality of optical disk storage devices 107 may be attached.

  In step S1301, the CPU 102 of the data library apparatus 101 confirms whether or not the door 1011 of the data library apparatus 101 is open. For the confirmation, the door opening / closing detection unit 114 is used. In this embodiment, the data library apparatus 101 is normally used with the door 1011 closed. The state where the door 1011 is opened is a special case, and corresponds to the case where the optical disk storage device 107 is removed or attached.

If the door is open (Y in the figure), the process proceeds to step S1304. If the door is not open (N in the figure), the process proceeds to step S1302.
Since step S1302 is a normal state in which the door 1011 is closed as described above, the data library apparatus 101 waits for an instruction from the server 115, and if there is an instruction from the server 115 (Y in the figure), the process proceeds to step S1303. If there is no command from server 115 (N in the figure), step S1302 is repeated until the command is received.
In step S1303, the commanded process is executed.

  In step S1304, the CPU 102 checks whether or not the optical disk storage device 107 is attached. For the confirmation, the optical disk storage device attachment / detachment detection unit 113 is used. If the optical disk storage device 107 is not attached (N in the figure), the process proceeds to step S1305 assuming that the attaching operation will be performed. If it is attached (Y in the figure), the door 1011 is already attached and the door 1011 is closed, or the removal work is performed thereafter, and the process returns to step S1301.

In step S1305, as a result of the confirmation in step S1304, the CPU 102 confirms whether or not the optical disk storage device 107 is attached at a location where the optical disk storage device 107 is not attached. If attached (Y in the figure), the process proceeds to step S1306. If it is not attached (N in the figure), the confirmation in step S1305 is repeated until it is attached.
In step S 1306, optical disk storage device information 1400 described later with reference to FIG. 14 is acquired from the storage device 112 included in the optical disk storage device 107 and transmitted to the server 115.

  Note that it is determined from the optical disk storage device information 1400 acquired in step S1306 whether the attached optical disk storage device 107 matches the optical disk storage device 107 selected in step S1002, and a different optical disk storage device 107 is attached. In such a case, the information display unit 104 may be used to notify the user. Further, the data library apparatus 101 may not accept processing for the optical disk storage device 107 until the optical disk storage device 107 selected in step S1002 is attached. In addition, the server 115 may perform the confirmation process of the attached optical disk storage device 107 in place of the data library device 101.

  Here, consider a case where an unused optical disk storage device 107 is selected in step S1002. In this case, since the optical disk storage device ID (701) cannot determine whether or not the attached optical disk storage device 107 is unused, the use status flag stored in the storage device 112 of the optical disk storage device 107 is used. to decide.

  FIG. 14 shows an example of optical disk storage device information 1400 stored in the storage device 112. 1401 is an optical disk storage device ID (701), and 1402 is a usage status flag of the optical disk storage device 107. The usage status flag is, for example, 1-bit information, and 0 is stored if there is no usage history, and 1 is stored if there is a usage history. In the example of FIG. 14, the optical disk storage device 107 to which the storage device 112 is attached has a usage history. A plurality of optical disks 108 are stored in the optical disk storage device 107. Normally, all unrecorded optical disks are initially stored. At this time, 0 (no usage history) is stored in the storage device 112 provided in the optical disk storage device 107 as the usage status flag of the optical disk storage device 107. When the optical disk storage device 107 is attached to the data library device 101 and data is recorded for the first time on any one of the optical disks 108 provided in the optical disk storage device 107, the usage status flag 1402 of the optical disk storage device 107 is set. , 0 (no usage history) is updated to 1 (use history). In this way, it is possible to appropriately grasp the usage status of the optical disk storage device 107 even from 1-bit information. Note that the method using the usage status flag 1402 stored in the storage device 112 is merely an example of grasping the usage status of the optical disk storage device 107, and other methods may be used. For example, the usage status may be recorded in a specific slot ID (901).

  Returning to FIG. 10, in step S1005, the CPU 301 of the server 115 delivers data to be recorded to the data library apparatus 101 determined in step S1002 via the data library interface unit 303, and requests data recording. In step S1006, when the server 115 receives an end notification of the data recording process in the data library apparatus (Y in the figure), the CPU 301 and the database management unit 307 update each table in step S1007. When the end notification of the data recording process is not received (N in the figure), the process of step S1006 is repeated until it is received.

  In this embodiment, the data to be recorded in the data library apparatus 101 is selected from the data recorded in the hard disk 105, but the data received from the network 116 via the network control unit 305 is converted into the data library apparatus. 101 may be recorded.

  In the data recording process described with reference to FIG. 10, when it is determined that the optical disk storage device 107 selected in step S1002 needs to be attached to the data library apparatus 101 in step S1003, the attachment process in step S1004 is completed. The problem is that data recording processing cannot be performed on the optical disk storage device 107.

  In particular, when the replacement work of the optical disk storage device 107 is performed manually by an operator, the time required for the replacement work increases. For example, in a data archiving system, the archiving process is often performed during the midnight when the burden on the host system using the data archiving system is low, and the replacement process of the optical disk storage device 107 is often performed at midnight. . For this reason, when there is no worker, the optical disk replacement process cannot be performed, and the archiving process does not end at the scheduled time, which may affect the subsequent work.

Therefore, in the embodiment described below, even when the mounting operation in step S1004 is not completed, the data to be recorded in the optical disk storage device 107 is temporarily stored in the other optical disk storage devices 107 remaining in the data library device 101. Thus, an efficient data recording method during the replacement operation of the optical disk storage device 107 will be described.
This method is particularly effective when a data recording request is issued to the optical disk storage device 107 that is not stored in the data library device 101.

  In the data archiving system of the present application, when it is determined that the optical disk storage device 107 selected in step S1002 needs to be attached to the data library device 101 in step S1003, the replacement process of the optical disk storage device 107 in step S1004 is performed. Until completion, the recording data for the optical disk storage device 107 selected in step S1002 is temporarily recorded on the optical disk 108 of another optical disk storage device 107 remaining in the data library apparatus 101. After the replacement processing of the optical disk storage device 107 is completed, the unrecorded optical disk 108 stored in the optical disk storage device 107 and the temporarily recorded optical disk 108 are replaced, whereby the data library apparatus 101 is replaced. To realize the recording of data to the optical disc storage device 107 that are not Attach.

  Hereinafter, the optical disk storage device 107 selected in step S1002 is referred to as a “first optical disk storage device”. Further, the optical disk 108 that temporarily records data to be recorded in the first optical disk storage device is referred to as a “temporary recording disk”. The optical disk storage device 107 that provides the temporary recording disk is referred to as a “second optical disk storage device”. An unrecorded optical disk 108 that is replaced with a temporary recording disk after the first optical disk storage device is attached to the data library apparatus 101 is referred to as an “alternative disk”.

  FIG. 15 is an example of a data recording process flow for a temporary recording disk in the data archive system of the present application. In the process of FIG. 15, the operator actually attaches the first optical disk storage device to the predetermined data library device 101 after it is determined in step S1003 that the first optical disk storage device needs to be attached. It is executed until.

  In step S1501, the selection processing unit 308 of the server 115 refers to the database management unit 307 to select the second optical disk storage device and the temporary recording disk from the data library device 101 to which the first optical disk storage device is attached. Make a selection. There are several possible methods for selecting the second optical disk storage device. For example, as a simple method, there is a method of selecting an optical disk storage device 107 having a free capacity capable of storing recording data. However, since a plurality of archiving processes are normally performed in parallel, a recording process for data to be originally recorded may occur in the second optical disk storage device. At this time, it should be avoided that the data to be originally recorded cannot be recorded for the recording process of the temporary recording disk. For this reason, it is desirable to put in control that lowers the priority of the optical disk storage device 107 that is frequently used or lowers the priority of the optical disk storage device 107 that has less free space.

  There are also several methods for selecting a temporary recording disk. For example, in a normal recording process, in the case of a system in which data is recorded in order from the slot ID (901) in ascending order, the normal recording process is performed by selecting an optical disk having a larger slot ID (901) as a temporary recording disk. The influence on the selection of the optical disk can be reduced.

  Further, if a plurality of optical disk storage devices 107 are simultaneously exchanged in one data library device 101, the number of optical disk storage devices 107 remaining in the data library device 101 is reduced, so that the optical disk storage device 107 that can be used as the second optical disk storage device. The possibility of not being increased. Therefore, the recording speed for the optical disk storage device 107 may be adjusted, and the timing for replacing the optical disk storage device 107 may be shifted. There are several methods for adjusting the recording speed. For example, a method in which recording processing is performed by one data recording / reproducing device 109 for one optical disk storage device 107 and recording processing is performed by one data recording / reproducing device 109 for the other optical disk storage device 107. There is.

  In step S1502, the CPU 301 of the server 115 checks whether or not the second optical disk storage device and the temporary recording disk are selected in step S1501, and if selected (Y in the figure), the CPU 301 of step S1503. If the process has not been selected (N in the figure), the process flow is terminated assuming that there is no second optical disk storage device or temporary recording disk that can be used.

  In step S1503, the CPU 301 delivers the data to be recorded to the data library apparatus 101 via the data library interface unit 303 to the data library apparatus 101 storing the second optical disk storage apparatus selected in step S1501. Request data recording.

In step S1504, if the CPU 301 does not receive a data recording process end notification from the data library apparatus 101 (N in the figure), the process of step S1504 is repeated until it is received. If a data recording process end notification is received (Y in the figure), the process proceeds to step S1505.
In step S <b> 1505, the CPU 301 and the database management unit 307 update each table. Specifically, in the optical disk storage device management table 700 shown in FIG. 7, the free space 705 of the second optical disk storage device is reduced by the temporary recording disk. Further, in the optical disk management table 900 shown in FIG. 9, the free space 903 of the temporary recording disk in the second optical disk storage device is reduced by the recorded data size.

  In step S1506, the CPU 301 confirms whether or not the first optical disk storage device mounting operation has been completed. If it has been completed (Y in the figure), the processing flow ends, and if it has not been completed. (N in the figure), the process returns to step S1501 to repeat the processing flow, for example, to temporarily record the next reserved data. In FIG. 15, the completion of the installation work of the first optical disk storage device is set as the end condition. However, another end condition may be set. For example, even if the installation of the first optical disk storage device has been completed, if there is a request for recording other data on the temporary recording disk and there is free space on the temporary recording disk, recording to the temporary recording disk Processing may continue. Further, considering that the operator installs the first optical disk storage device, a predetermined time interval is set between the start of the flow of FIG. 15 and the start of the process of step S1506. May be.

  In this embodiment, since the replacement disk of the first optical disk storage device and the temporary recording disk of the second optical disk storage device need to be exchanged after the installation work of the first optical disk storage device is completed, temporary storage for managing them A data management table is required. Next, the temporary storage data management table will be described.

  FIG. 16 shows an example of the temporary storage data management table 1600. Reference numeral 1601 denotes the ID of the second optical disk storage device, and reference numeral 1602 denotes the optical disk ID of the temporary recording disk. 1603 is the ID of the first optical disk storage device, and 1604 is the optical disk ID of the alternative disk. The temporary storage data management table 1600 is stored in the memory 302 of the server 115 or the hard disk 117, and is managed by the CPU 301 and the database management unit 307. Also, the data registration process for the temporary storage data management table 1600 is performed in step S1505 in FIG.

  FIG. 17 is a processing flow executed by the server 115 in the mounting process of the optical disk storage device 107 of the data archive system of the present application, and is performed following the processing flow of FIG.

In step S <b> 1701, the CPU 301 of the server 115 acquires information 1400 on the optical disk storage device attached to the data library device 101.
In step S1702, the CPU 301 confirms from the information acquired in step S1701 whether the attached optical disk storage device 107 matches the first optical disk storage device. If not (N in the figure), the CPU 301 Execute the process. In step S1703, the CPU 301 notifies the user using the display device 118 that the optical disk storage device 107 attached to the data library apparatus 101 is different from the first optical disk storage device, and ends the processing flow.

If it is confirmed in step S1703 that the first optical disk storage device is attached (Y in the figure), the process of step S1704 is executed.
In step S1704, the CPU 301 refers to the temporary storage data management table 1600, determines whether or not an optical disk replacement process is necessary for the attached first optical disk storage device, and if replacement is necessary (Y in the figure). Then, the process of step S1705 is executed, and if the exchange is not necessary (N in the figure), the process flow is ended.
Step S1705 is an optical disk replacement process, which will be described with reference to FIG.

FIG. 18 is an example of the processing flow of the optical disk replacement process.
In step S1801, the selection processing unit 308 selects an alternative disk. Although several alternative disk selection methods are conceivable, an unrecorded optical disk is basically selected. If it is an unrecorded optical disk, the capacity management of the optical disk storage device 107 is easy, and the management of the group ID is not necessary.

  If it is determined in step S1802 that the temporary recording disk is being recorded or reproduced and cannot be replaced immediately (Y in the figure), the process of step S1804 is executed, and if the temporary recording disk can be replaced immediately ( N) in the figure, the process of step S1803 is executed.

  In step S1803, the optical disk transport device 106 of the data library apparatus 101 performs replacement processing between the replacement disk and the temporary recording disk. Specifically, the substitute disk is taken out from the first optical disk storage device, and the temporary recording disk is taken out from the second optical disk storage device, and the substitute disk is inserted into the slot in which the temporary recording disk of the second optical disk storage device is stored. The temporary recording disk is stored in the slot in which the substitute disk of the first optical disk storage device was stored. By completing the storage, the processing flow is completed.

In step S1804, since the temporary recording disk cannot be moved, the optical disk transport apparatus 106 of the data library apparatus 101 only moves the substitute disk. The substitute disk is taken out from the first optical disk storage device and stored in the slot in which the temporary recording disk of the second optical disk storage device was stored.
In step S1805, the CPU 102 of the data library apparatus 101 confirms whether or not the temporary recording disk recording or reproduction process is completed and is movable, and if it cannot be moved (N in the figure), until it becomes movable. The process of step S1805 is repeated. If it is movable (Y in the figure), the process proceeds to step S1806.
In step S1806, the optical disc transport device 106 of the data library device 101 stores the temporary recording disc in the first optical disc storage device, and the operation flow is ended.

  Returning to FIG. 17, in step S1706, each table is updated, and the processing flow ends. Specifically, in the optical disk storage device management table 700, the free space 705 of the first optical disk storage device is reduced by the data recorded on the temporary recording disk, and the free space 705 of the second optical disk storage device is substituted. Increased by the amount of free disk space. Also, the information of the temporary recording disk and the alternative disk is changed in the optical disk management table 900 of the first optical disk storage device and the second optical disk storage device, respectively. Further, the data for which the exchange work has been completed is deleted from the temporary storage data management table 1600 shown in FIG.

In FIG. 17, the table is updated all at once in step S1706. However, the table may be updated every time each process is completed.
Further, FIG. 17 illustrates the case where the replacement disk and the temporary recording disk to be replaced are one set, but there may be two or more sets of optical disks to be replaced. In that case, after step S1706, it is confirmed whether or not the replacement processing of all the temporary recording disks registered in the temporary storage data management table 1600 is completed for the first optical disk storage device. If not, the process returns to step S1706.

In FIG. 18, when the replacement disk and the temporary recording disk are exchanged, the disk is stored in the same location as the slot in which the disk is stored, but may be stored in another slot.
When the group ID (702) of the second optical disk storage device that stores the temporary recording disk is the same as the group ID (702) of the first optical disk storage device that should originally store the disk. In this case, the replacement process of the optical disk 108 may not be performed. However, even if the group ID (702) is the same, if one piece of data is divided and stored in a plurality of optical discs 108, the plurality of optical discs 108 are collected in one optical disc storage device 107. It is better to make it. This is because if the data is stored in a different optical disk storage device, the optical disk storage device 107 needs to be replaced when the data is reproduced.

  Also, the second optical disk storage device storing the temporary recording disk may not be removed from the data library apparatus 101 until the temporary recording disk replacement process is completed. That is, in step S1103 in FIG. 11, if a temporary recording disk is stored in the second optical disk storage device, it is determined that it cannot be removed. When there is a removal request, the fact that the data of the other optical disk storage device 107 is recorded in the second optical disk storage device is connected to the information display unit 104 of the data library device 101 or the server 115. It may be displayed on the display device 118 and notified to the user.

  In this embodiment, the temporary recording disk is selected from the optical disk storage device 107 for normal recording. However, the data library apparatus 101 may include an optical disk storage device dedicated to the temporary recording disk. In this embodiment, the server 115 and the data library apparatus 101 constitute an archive system. However, the server function may be integrated into the data library apparatus 101.
