  The media processing apparatus 1 according to the present embodiment stores a plurality of disks in the stacker 12 and can convey each disk to the disk drive 13 and the disk printer 14 by the autoloader 15. As a result, data recording and printing are appropriately performed on a plurality of disks, and a plurality of recorded disks can be issued.

By the way, when a new disk is created by using an image file recorded on the duplication source disk, the same disk as the duplication source can be created. Therefore, the image file can be used as original data for duplication.
The inventor considered that there is a need for a function for managing original data recorded on a plurality of discs against the background of increasing demand for rewriting (data migration) of data-recorded discs. In order to meet this need, the media processing apparatus 1 extracts each image file as original data from a plurality of discs stored in the stacker 12, and creates a plurality of original data in batch (original data batch creation processing). ) Can be executed.

FIG. 3 is a flowchart showing original data batch creation processing.
This original data batch creation processing is executed by functions of the information acquisition unit 51, the information processing unit 52, the display control unit 53, and the like included in the control unit 23.
In this case, the control unit 23 executes functions of the information acquisition unit 51, the information processing unit 52, the display control unit 53, and the like by executing the program of the management application 31 stored in the storage device 24. An operation screen (not shown) for inputting an instruction is displayed. Then, the original data batch creation process is started in accordance with the user instruction input via the input unit 21.
In the present embodiment, a data-recorded disk (referred to as a recorded disk) is stored in the stacker 12 designated in advance.

When the original data batch creation process is started, the control unit 23 first transports one recorded disk from the designated stacker 12 to the disk drive 13 by the autoloader 15 (step S11). If another disk is in the disk drive 13, the disk is transported to another stacker 12 by the autoloader 15.
Next, the control unit 23 uses the disk drive 13 to reproduce the data recorded on the stored disk and extract an image file (step S12).
Next, the control unit 23 stores the extracted image file as original data in the storage device 24, and additionally writes a path name indicating the storage destination in the management table KT (step S13).

The management table KT is used as management data for managing the original data stored in the storage device 24. More specifically, the path name indicating the storage destination of the original data is read from each original data. Data in text file format described in order (playback order). The management table KT may be automatically created when the original data batch creation process is first executed, or may be manually created by the user.
FIG. 4 is a diagram showing an example of the management table KT in a table format.
In the management table KT, the first line is an identifier, and each line describes a record corresponding to one disk in the order of disk playback. In the example of FIG. 4, the items (fields) constituting the record are “Path”, and the path name of the original data is described in each line thereafter. Note that a serial number (hereinafter referred to as “disk number”) displayed at the beginning of each line is a number automatically assigned by software indicating the management table KT in a table format.
In addition to the path name, information such as the volume label of the disk from which the original data is read may be added to the management table KT.

When the process of step S13 in FIG. 3 is finished, the control unit 23 determines whether or not reading of all recorded discs (reading of image files) is finished (step S14). In this case, when the reading of all the disks in the designated stacker 12 is completed, or when the number of read sheets is designated by the user, the control unit 23 finishes reading the designated number of disks. If it is, it is determined that all reading has been completed.
When the reading is not completed (step S14; NO), the control unit 23 proceeds to the process of step S11 and starts reading the next disk. As a result, the processes of steps S11 to S13 are executed again, the reproduction of the next recorded disk held in the stacker 12 is started, and the path name of the disk is added to the management table KT.
In this way, the original data corresponding to a plurality of discs is created in a batch and the batch creation is performed by repeatedly executing the processes of steps S11 to S13 until the reading of the original data from all the discs is completed. The original data management table KT is created.
When reading of all the disks is completed (step S14; YES), the control unit 23 ends the original data batch creation process.

The media processing apparatus 1 can duplicate the same disk as the disk from which the original data is read using the original data by using software or the like that writes a known image file to the disk.
Further, since the management table KT described above is a text file, the user can easily browse the contents using general-purpose software. In this case, the user can directly confirm the number of original data and the path name by browsing the management table KT.
Further, the management application 31 for the publisher 2 has a function of issuing a duplicate disk desired by the user by using the management table KT. The operation screen GM and operation in this case will be described.

FIG. 5 is an insertion data management screen GM21 showing an example of the operation screen GM.
On the insertion data management screen GM21, various operation buttons for instructing a reference destination of a file corresponding to the management table KT are displayed, and the management table KT designated by the user can be read by a predetermined operation of the user. it can.
FIG. 5 shows a state in which the management table KT shown in FIG. 4 has been read.
Since the path name of the original data is described in the management table KT (see FIG. 4), when the management table KT is read, the path names of the original data are in order (disc playback) as shown in FIG. Are displayed in order). Since this display corresponds to a list of original data stored in the storage device 24, the user can grasp the list of original data.

Furthermore, a check box CK11 is displayed for each original data (each path name) on the insertion data management screen GM21. Each check box CK11 is selectively checked according to a user operation. The original data corresponding to the checked check box CK11 is selected as the original data to be copied, and the original data corresponding to the unchecked check box CK11 is excluded from the copy target.
Thereafter, when the start of disk issuance (duplication start) is instructed by a predetermined operation by the user, the control unit 23 transmits each original data checked in the check box CK11 to the publisher 2, and the publisher 2 does not record the data. Write to each disc.
In this way, one or a plurality of duplicate disks selected by the user among a plurality of original data can be created in a batch. If the user also specifies the print contents of the disc, the data corresponding to the print contents is also sent to the publisher 2 and printing on the duplicate disc is also performed. This printing is the same as a conventional publisher.

As described above, according to the present embodiment, since original data of a plurality of recorded disks can be created at once, a large number of original data for duplication can be created easily and in a short time. In this case, a plurality of original data can be handled collectively on the host apparatus 3 side, and by selectively using this original data, a desired duplicate disk can be easily created at a desired timing.
Moreover, since the original data is the image data itself recorded on the recorded disc that is the copy source, a complete duplicate disc can be easily created including the volume label and creation date.
In addition, since it is not necessary to convert the file format to a file format that can be handled by the OS of the host device 3 until the original data is acquired and the duplicate disk is created, the processing time can be shortened because the conversion process is not performed. In addition, the storage area can be small.
Furthermore, even if the disc format of the recorded disc is a format that cannot be read by the OS of the host device 3 (for example, UDF2.5), the original data can be created and duplicated.
As a result, in this embodiment, the original data of a plurality of disks can be centrally managed with data suitable for duplication.

Further, since the control unit 23 of the host apparatus 3 records the selected original data among the stored original data on the disk, it is possible to create a duplicate disk without preparing a copy source disk at the time of duplication. .
Further, in this configuration, since the management table KT (see FIG. 4) for managing the original data is created, the original data can be grasped based on the management table KT, and the original data can be easily reused. be able to.
In this case, the path name of the original data is described in the disk reading order (playback order) in the management table KT. Therefore, the storage location of the original data, the copy source disk, etc. Can grasp.

Furthermore, since the management table KT is in a text file format, the amount of data can be reduced, and the contents can be easily confirmed using general-purpose software.
Further, the control unit 23 receives selection of original data to be replicated based on the management table KT (see FIG. 5), and when there are a plurality of original data to be replicated, the selected original data is stored for each disk. In this way, a plurality of duplicate disks having different recording contents can be easily created in a batch.

The media processing apparatus 1 according to the present embodiment also stores data in the stacker 12 in the same manner as the original data batch creation process when data is read from a recorded disk in a file format that can be handled by the OS of the host apparatus 3. By sequentially reading out a plurality of recorded discs and storing them in the storage device 24, it is possible to collectively create file format data of a plurality of discs.
In this case, the data in the file format of each disk is stored separately for each disk, and when the data in the file format is read from a plurality of recorded disks, a large number of folders for each disk are formed. In this case, it is difficult to find out which folder is taken from which disk, and it may be difficult to search.
For example, if you want to read 50 disks and check the 30th data, you have to count the order and find the 30th folder from the beginning. If the order of the disks is unknown, it will be more difficult to find.

Therefore, in this embodiment, when data is read from a recorded disc in a predetermined file format and stored, the volume label (see FIG. 2) is read from the recorded disc, and the read volume label is used as the folder name. A folder is created and data is stored in this folder.
FIG. 6 is a diagram showing a specific example of a folder.
The example of FIG. 6 shows a case where five discs with volume labels “OKA2000”, “OKA2001”, “OKA2002”, “OKA2003”, and “OKA2004” are read. The first half of the folder name is read date / time information, and the second half is a volume label.

More specifically, as shown in FIG. 6, the folder name corresponding to the disk with the volume label “OKA2000” is “20120925191811.OKA2000”, which indicates the date and time when “20120925191811” in the first half is read, It shows 19:18:11 on September 25, 2012. In addition, a volume label “OKA2000” is attached to the latter half of the “. (Period)”.
As shown in FIG. 6, folder names corresponding to the disks of the volume labels “OKA2001”, “OKA2002”, “OKA2003”, and “OKA2004” are created according to the same rule.
According to this configuration, since the folder name is automatically created, the user can easily visually confirm which folder is taken from which disk.

In addition, since the first half of the folder name is read date and time information, the user can easily visually check the read date and time, and it is possible to avoid duplicating folder names.
If the folders are sorted by name, they can be sorted in the order they were read.
Thus, the user can easily search for data of a desired disk (for example, a disk to be copied) based on any of date / time information, volume label, and reading order.

  In the above-described embodiment, the case where the original data created in a batch is stored in the storage device 24 in the host device 3 has been described. May be. In this case, the original data can be shared by other host devices 3 or personal computers connected to the network storage.

Further, although cases have been described with the above embodiment where the present invention is applied to the media processing device 1 in which the publisher 2 and the host device 3 are configured separately, the present invention is not limited to this, and the present invention is not limited to this. The present invention may be applied to an integrated media processing apparatus in which the host apparatus 3 and the host apparatus 3 are integrated. For example, the present invention can be applied to a multifunction device (a so-called printer multifunction device) in which a printer, a copier, and a scanner are integrated.
Further, although cases have been described with the above embodiment where the present invention is applied to a media processing apparatus that targets a disk as a processing target, the present invention is widely applied to media processing apparatuses that target a medium other than a disk as a processing target. be able to.

Furthermore, in the present embodiment, a case has been described in which a control program for performing original data batch creation processing or the like is stored in advance in the storage device 24 of the host device 3. The program may be stored in a computer-readable recording medium such as a recording medium, an optical recording medium, or a semiconductor recording medium, and the computer may read and execute the control program from the recording medium. The control program may be downloaded from a distribution server on the communication network.
In addition, the configuration and processing of the media processing device 1, the publisher 2, and the host device 3 can be appropriately changed without changing the gist of the present invention, regardless of the modification described above.
