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

摘要

PROBLEM TO BE SOLVED: To guarantee the smooth and continuous reproduction of sound and video data even if seek time of several hundred milliseconds occurs by searching continuous space areas having a specific size or above for guaranteeing continuous reproduction for a reproducing device and not straddling over a zone boundary by referring to read sector information and sequentially writing a video object in the searched continuous space areas. SOLUTION: A specific size is defined as a size corresponding to N-ecc pieces of ECC blocks represented by an expression to an optical disk in which a recording area is divided into plural ECC blocks in which an area where N-sec pieces of S-size-byte sectors continue is defined as an ECC block. In the expression, DN-ecc is the number of ECC blocks having a defective sector in continuous space areas, Vo is the output transfer rate of a track buffer of a reproducing device, Tj is the maximum jump time of an optical pick-up of the reproducing device, TS is the time needed for the optical pick-up to skip dN-ecc pieces of ECC blocks and Vr is the input transfer rate of the track buffer.
