Method for managing file system in optical disk apparatus

Abstract

The invention relates to a file system administration method of CD equipment, which is characterized by the following: CD reads File System and Disc-ID in the specific disc area, which stores in non-volatile storage to administrate insides; The File System searches and refers the operation of data storage in the non-volatile storage when the CD reads or executes.

Description

【Technical field】 [0001] The present invention relates to a file system management method of an optical disc device for storing and managing a file system (File System) recorded in a specific area of ​​an optical disc in an optical disc device similar to a video recorder. 【Background technique】 [0002] Recently, a disc similar to DVD (DVD: Digital Versatile Desc) that can store or read high-quality video data and high-quality audio data for a long time and a disc recorder that can read or An optical disc device that records data stored on an optical disc is widely used. [0003] On the other hand, as shown in FIG. 1, the above-mentioned optical disc apparatus similar to a video recorder is composed of an optical pickup, a VDR (Video Disc Recorder) system 12, a microcomputer 13, and a memory 14 and the like. When the installation CD 10 is inserted into the device, the above-mentioned microcomputer 13 runs and controls the above-mentioned VDR system 12, reads the navigation ...
