Abstract:
An optical disc recording apparatus for recording video objects on an optical disc, whereina recording area of the optical disc is divided into a plurality of sectors, with each set of Nsec consecutive sectors forming one ECC block, each sector having a size of Ssize bytes,each video object is composed of a plurality of packs, each pack having a size of Ssize bytes,recording sector information showing data assignment for sectors on the optical disc, andthe minimum size is the number of ECC blocks which is represented as ""Necc"" in the following formula:N.sub.-- ecc=Vo*Tj/((Nsec*8*Ssize)*(1-Vo/Vr)),where ""Tj"" represents a maximum jump time of an optical pickup of a reproduction apparatus, ""Vr"" represents an input transfer rate of a track buffer of the reproduction apparatus, and ""Vo"" represents an effective output transfer rate of the track buffer,said optical disc recording apparatus comprising:a reading means for reading the sector information from the optical disc;a detecting means for detecting a series of consecutive unassigned sectors on the optical disc by referring to the read sector information, a total size of the series being greater than the minimum size, the minimum size corresponding to a data amount that ensures the reproduction apparatus for uninterrupted reproduction of the video object; anda recording means for recording the video object including Ssize-byte packs onto the detected series of consecutive unassigned sectors.
