How to format search error area in optical application

摘要

1. TECHNICAL FIELD OF THE INVENTION;A method for processing search errors in an optical application device, the method of formatting RAM storage, particularly in the case of a search error due to a disk error, storing the search error area as a start / end address in RAM Therefore, the present invention relates to an efficient application formatting method of RAM control for quickly selecting a skip (SKIP) or the like by referring to an area at the time of RETRY.;2. The technical problem to be solved by the invention;It is possible to reduce unnecessary search time for RAM search by setting the format that saves the search error area of the disk in RAM under optimum conditions, and to provide a method of optimizing RAM size by operating a systematic format.;3. Summary of Solution to Invention;If the microcomputer (1-60) is buffering the start / last address shown in the search error and the track is changed, the current track number is stored, and then the format of FIG. 5 is matched to the RAM device (1-70) with the buffered data. After recording and storing, the next RAM address pointer is stored in the link byte when H'00 is written if there is no link depending on the presence or absence of the link.;4. Important uses of the invention;How to save search error area in optical applications.
