Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device that manages an optical disk using an autochanger.

[0002]

2. Description of the Related Art In recent years, an increasing number of devices have been constructed to construct a database of image information on an optical disc, and to search and utilize these. Furthermore, a method is also adopted in which a plurality of optical disks are collectively stored in an autochanger, and these are used collectively.

In this case, the automatic changer has 20 to
It is possible to store 30 optical disks, and usually one or two optical disk drives are built in. In this way, when using the autochanger, all the optical disks in the autochanger are treated as one data storage, and this one data storage is targeted when searching or the like.

[0004]

However, since the user has no way of knowing in which storage element of the autochanger the optical disc is set, the individual optical disc cannot be accessed.

An object of the present invention is to record identification information such as a volume label of an optical disk in a non-volatile storage device such as a hard disk, and by using this method, each optical disk is set in which storage element. This is to improve the operability of the autochanger by indicating to the user whether or not each optical disk in the autochanger can be easily accessed.

[0006]

The electronic device of the present invention reads out identification information such as a label of each optical disk housed in an autochanger and records the identification information in a non-volatile storage device, and a means for storing each optical disk. Means for displaying the identification information recorded on the non-volatile storage device on the display at the time of access, and the optical disc corresponding to the identification information on the display selected by the user is automatically loaded into the optical disc drive with the built-in autochanger to access the optical disc. It is equipped with a means to do.

With the above configuration, when searching for individual optical disks in the autochanger, the desired optical disk can be uniquely selected after being confirmed on the screen by its label or the like, so that it is housed in the autochanger. Each optical disc can be accessed and the operability of the autochanger is greatly improved.

Embodiment 1 of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic filing apparatus according to the first embodiment of the present invention, in which 1 is a central processing unit for controlling each device and logical judgment, 2 is a liquid crystal display, CRT (cathode ray). A display device 3 such as a tube is an autochanger for housing the optical disk 4. Reference numeral 3a is a part of the autochanger 3, and is a throttle for inserting the optical disk 4 into the autochanger 3. Reference numeral 3b is a part of the autochanger 3, which is an element for accommodating the optical disc 4, and is usually 2
There are 0 to 30. Reference numeral 3c is a part of the autochanger 3, and is an optical disk drive for reading and writing data with respect to the optical disk 4 when it is set therein. 3d is a part of the autochanger 3, and is an elevator that conveys the optical disk 4 between the throttle 3a and the element 3b or between the element 3b and the built-in optical disk drive 3c. Reference numeral 5 is a hard disk drive that stores the number of optical disks 4 housed in the autochanger 3 and the label of the optical disk on each element. "The hard disk drive stores the optical disk management file. 6 is a command sent by the user to this system. Reference numeral 7 denotes a main storage device for storing a program to be executed by the central processing unit 1 and reading the "optical disk management file" from the hard disk drive 5.

FIG. 2 shows the contents of the "optical disc management file". That is, the number of optical disks 4 stored in the autochanger 3, the number of optical disks stored in each element 3b, and the optical disk label are recorded in this file. However, MAX is the number of elements, and is usually 20 to 30. This file is initialized before use. That is, before use, the "number of stored optical disks" is "0" and all "disk labels" are "NULL".

First, the flow of processing for storing an optical disk in the autochanger will be described with reference to FIG.
When the user gives a storage instruction with the keyboard 6, the central processing unit 1 can read the "optical disc management file" from the hard disk drive 5 into the main storage device 7, and read the "number of stored optical discs" recorded therein. Reference is made (S10). Then, the central processing unit 1 checks whether or not "the number of stored optical disks" = MAX (S20), and if so, displays "auto changer is full" on the display unit 2 to perform the process. Suspend. In step (S20), "number of stored disks" ≠ M
When it is determined to be AX, the process proceeds to step (S30), and the central processing unit 1 issues a command to the autochanger 3 to store the optical disc from the throttle 3a into the "number of stored optical discs + 1" element 20 ( S40). After that, the autochanger 3 opens the door of the throttle 3a. At this time, if the user inserts the optical disk into the throttle 3a, the autochanger 3 puts the optical disk on the elevator 40, carries it to the "number of stored optical disks + 1" element 3b, and stores it. Further, the central processing unit 1 is an auto changer 3
To the internal optical disk drive 3c (S50), the process moves to FIG. 4, and the label of the optical disk is read (S60). After that, the central processing unit 1 issues a command to the autochanger 3 to carry the optical disk back to the "number of stored optical disks + 1" element 3b again (S70). Then, the central processing unit 1 changes the "disc label" corresponding to the "number of stored optical discs + 1" element of the "optical disc management file" data in the main storage device 7 to the label read from the optical disc (S80). ). Also,
1 is added to the value of "the number of stored optical disks" (S8)
0). Finally, the central processing unit 1 writes back the changed "optical disc management file" data in the main storage device 7 to the "optical disc management file" in the hard disk drive 5 (S90).

Next, the access processing to the stored optical disk will be described with reference to FIG. If the user gives an instruction to read the data on the optical disk using the keyboard 6,
The central processing unit 1 can read the "optical disk management file" from the hard disk drive 5 into the main storage device 7, and refer to the "disk label" recorded therein (S100). Then, the central processing unit 1 displays the list of "disc labels" on the display unit 2 as shown in FIG. 6 (S110). After that, the user designates the optical disc to be searched with the keyboard 6. If the user selects “1 Sales 1 Division”, the central processing unit 1
Issues a command to the autochanger 3 to transport the optical disc from the element # 1 to the built-in optical disc drive 3c and read desired data of the optical disc onto the main storage device 7 (S120, S130). Then, the central processing unit 1 displays the read data on the display device 2 (S140).

[0013]

According to the present invention, the label of each optical disk in the autochanger can be displayed on the display and a desired optical disk can be selected from this, and as a result, a specific one of a plurality of optical disks can be easily selected. An electronic device that can be accessed and has high operability can be provided.
