Abstract

PURPOSE:To make it unnecessary to execute manually the restoration and the exchange of a deteriorated medium by hand by substituting automatically a new medium before the deterioration of the medium shows itself. CONSTITUTION:An accessor 7 reads the date at which the medium was started to use from a recording part 8, and calculates the used term by a used term calculating part 9. If the calculated used term exceeds a definite value, it is considered that the using term of the medium becomes near expiration, and the new medium is taken out of a storehouse 2 by the accessor 7, and is loaded to a deck 4. Next, the data of the medium loaded in the deck 3 is read out, and the data is transcribed to the new medium loaded in the deck 4. The medium loaded in the deck 3 is taken out by the accessor 7, and is discharged from a discharge port 6. After the finish of the read-out of the medium loaded in the deck 4, the medium is taken out by the accessor 7, and is transferred to a label entry part 5. Thus, it is unncessary to execute restoration and the exchange of the deteriorated medium by hand.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a library-type optical disk device, in particular:
This invention relates to an optical disk medium exchange method.

2. Description of the Related Art Conventionally, in library-type optical disk devices of this type, when an optical disk medium (hereinafter simply referred to as a medium) is used for a long period of time, the medium deteriorates and data stored on the medium cannot be read. For this purpose, by looking at the file that records the usage period of each medium, the operator will be able to identify the media that has been used for a certain period of time and instruct them to replace the media by rewriting it with a new one. There was a need.

mm to be solved by the invention The above-described conventional library-type optical disk device had the disadvantage that instructions from the operator were required to replace a deteriorated medium with a new medium, and the system was not automated.

The present invention has been made in view of the above-mentioned conventional situation,
Accordingly, an object of the present invention is to provide a novel optical disc device that makes it possible to eliminate the above-mentioned drawbacks inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the library-type optical disk device according to the present invention records the date when the medium was started to be used, and calculates the period of use so that the period of use is a certain period. It has a function to automatically replace old media with a new medium, and a function to write a label on the new medium.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention includes a warehouse 1 having shelves for storing a large number of media, a warehouse 2 having shelves for storing new and unused media, and a warehouse for recording data on media. a deck 3.4 for reading or reading recorded data; a label writing unit 5 for writing a volume label name on a new medium;
a discharge port 6 for discarding old media that has been used for a certain period of time; an accessor 7 for transporting the media between the warehouse 1.2, the deck 3.4, the label writing section 5, and the discharge port 6;
It is comprised of a storage section 8 that stores the start date of use of the medium, and a usage period calculation section 9 that calculates the usage period.

Next, the operation of this embodiment will be explained. When reading data from a certain medium, the accessor 7 first takes out the medium from the warehouse 1 and loads it into the deck 3. The accessor 7 then reads the date on which the medium began to be used from the recording section 8, and the usage period calculation section 9 calculates the usage period. If the calculated usage period exceeds a certain value, it is assumed that the usage period of the medium is approaching, and a new medium is taken out from the warehouse 2 by the accessor 7 and loaded into the deck 4.
Next, the data on the medium loaded on deck 3 is read and the data is transferred to a new medium loaded on deck 4.
The medium loaded in the deck 3 is taken out by the accessor 7 and discarded from the discharge port 6. After normal reading is completed, the medium loaded in the deck 4 is taken out by the accessor 7 and transferred to the label writing section 5. A label for the volume of the medium is printed on the surface of the case of the medium in the label writing section 5.8 Next, the medium is
The original medium in warehouse 1 is returned to the same position on the shelf where it was stored.

As described in detail, the present invention automatically transfers data written on an old medium to a new medium because the medium is expected to deteriorate after a certain period of use. and discard the old media.

In this way, according to the present invention, by automatically replacing the medium with a new medium before the deterioration of the medium appears, it is possible to obtain the effect that there is no need to manually restore or replace the deteriorated medium.

Claims (1)

[Claims] A warehouse with shelves for storing a large number of optical disk media, a deck for writing data to and reading data from the optical disk media, and a deck for taking out the optical disk media from the shelves and transporting them to the deck position, and storing the media on the deck. In a library-type optical disk device equipped with an accessor for loading optical disks, it is possible to prevent deterioration of the optical disk medium by having a storage section that stores the start date of use of each optical disk medium and a use period calculation section that calculates the period of use. A library-type optical disk device characterized by having a function of automatically replacing the medium with a new one before it becomes unreadable.
