OPTICAL DISK RECORDING DEVICE, RECORDING METHOD, OPTICAL DISK AND PROGRAM RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To insure smooth and continuous reproduction of sound and video data even if seek time of several hundred milliseconds occurs by searching continuous free areas which are equal to or larger than a specific size insuring continuous reproduction for a reproducing device and also does not stride over a zone boundary by referring to read sector information and successively writing a video object in the searched continuous free areas. SOLUTION: The specific size is defined as a size corresponding to N pieces of blocks represented by the expression to an optical disk whose recording area is divided into plural blocks in which an area where sixteen 2048-byte sectors continue is defined as a block. Here, dN is defined as the number of ECC blocks having a defective sector in continuous free areas, Vo is defined as the output transfer rate of a track buffer of a reproducing device, Tj is defined as the maximum jump time of an optical pick-up of the reproducing device, TS is defined as time needed for the optical pick-up to skip dN pieces of blocks and Vr is defined as the input transfer rate of the track buffer.
