AI Technical Summary

Problems solved by technology

At this time, compared with the high-frequency mode, the response speed is slower, so when scanning the video recorder at a high speed, the speed is slower than the previous shutdown period, and the screen is cut off, resulting in defects in the scanned data, which may become a source of dissatisfaction for consumers. factor

Abstract

The invention relates to high-speed scanning speed improving method of optical recording media that comprises steps as following: (a) step of user running the data storing command stored in the optical recording media; (b) step of judging said data which gains the user reading command is in open time section or closed time section; (c) if said data is in open time section, the kind of relative optical recording media is recognized, said open time section is recognized in definite filed of the optical recording media; (d) step of reading relative data with high-frequency mode based on said opentime section recognized. The invention can gain disc data by high-frequency address, so the responding speed can be decreased, the problem of image cutting when the optical recording media scans quickly can be avoided.

Description

technical field [0001] The invention relates to a method for improving high-speed scanning speed of an optical recording medium, in particular to a method for improving a high-speed scanning speed of an optical recording medium for accelerating the playback response speed of the optical recording medium and preventing picture cut-off phenomenon during high-speed scanning. Background technique [0002] Recently, personal computers (PCs) have been able to provide AV (audio-visual) information such as music and images as their functions have improved. Since the amount of AV information is quite large, optical disks such as CD-R (Compact Disc-Recordable) and DVD+R (Digital Versatile Disc+Recordable) have attracted attention as information recording media. Due to the drop in the price of optical discs, as information playback devices, optical disc devices are widely used as one of the peripheral devices of personal computers. [0003] As a file system utilizing recordable inform...
