JPS62283470A - Area management system for optical disk medium by high speed secondary storage device - Google Patents

Abstract

PURPOSE:To shorten a time required for referring the updating by using a high speed secondary storage device consisting of an automatic medium recognition means, an automatic transfer means, the referring and updating means of optical disk management information and an area management information updating means on the medium. CONSTITUTION:When an optical disk medium is set on an optical disk device 5, the automatic medium recognition means 1 recognizes the medium of the optical disk to obtain medium information. Based on this medium information, the automatic transfer means 2 transfers the area management information on the optical disk to the high speed secondary storage device 7. When an area reference request on the optical disk is generated from an optical disk using program 8, the referring and updating means 3 obtains area information from the optical disk area management information on the device 7 and based on this area information, the program 8 refers to the area on the disk. When the updating request for the area information is generated from the program 8, the area information on the device 7 is updated by the means 3, an updating means 4 is activated and the management information is simultaneously updated.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application The present invention uses a high-speed secondary storage device to
Directly refer to 6ft area management information of optical disc media! J!
View and update optical disc area management information faster than updating.
Optical Disc Area Management System for Updating Conventional Technology Conventionally, an optical disc area management system involves directly updating the area management information on the optical disk medium with a reference number.

FIG. 2 is a block diagram showing a conventional area management system for an optical disc.

Problems to be Solved by the Invention Optical discs have a large capacity and contain a large amount of area management information, and one input/output time is long, so the L area management method takes a long time.

The present invention has been made in order to solve the above-mentioned problems inherent in the conventional technology. Therefore, an object of the present invention is to quickly store area management information of an optical disk by using a high-speed secondary storage device. The object of the present invention is to provide a new area management method for an optical disk medium that enables 1)) referencing and updating;

Means for Solving the Problems In order to achieve the above object, the area management method for an optical disk medium using a high-speed secondary recording device according to the present invention automatically recognizes that an optical disk medium is set in an optical disk device. an automatic medium recognition means for automatically transferring area management information of the optical disk to a high-speed secondary storage device based on the optical disk medium information obtained by the automatic medium recognition means; and a means for updating the area management information on the assigned optical disk activated by the updating means.

EXAMPLE Hereinafter, 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.

In FIG. 1, one embodiment of the present invention includes an automatic medium recognition means 1 that automatically recognizes that a disk medium has been set in an optical disk device, and a high-speed secondary storage device 7 that stores area management information of the optical disk. automatic transfer means 2 for automatically transferring
, means 3 for referencing/updating optical disk area management information in the high-speed secondary storage device 7-A, and area management information on the optical disk E''
p information updating means 4, optical disk device S, and CP
It is composed of a U 6, a high-speed secondary storage device 7, and an optical disk usage program 8.

Next, the operation of the present invention will be explained with reference to the drawings.

First, when an optical disk medium is set in the optical disk SF device 5, the automatic medium recognition means 1 recognizes the optical disk medium and obtains medium information.

Based on the medium information, the automatic transfer means 2 transfers the area management information on the optical disk to the high-speed secondary storage device 7. When an area reference request on the optical disk is generated from the optical disk usage program 8, the means 3 for referencing and updating the optical disk area management information on the high-speed secondary storage device 7 extracts area information from the optical disk area management information on the high-speed secondary storage device 7. is obtained, and based on the area information, the optical disc usage program 8 references the area on the optical disc. Also,
When a request to update the area information on the optical disk is issued from the optical disk usage program 8, the means 3 for referencing and updating the optical disk area management information on the high-speed secondary storage device 7 updates the optical disk area management information on the high-speed secondary storage device L. The area information is updated, the means 4 for updating the area management t5 information on the optical disc is activated, and the area management 1n information on the optical disc L is also updated at the same time.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, by using a high-speed secondary storage device, it is possible to reduce the time required to update the reference area of an optical disk.
