Abstract:
An optical disc recording apparatus for recording a video object on an optical disc, whereina recording area of the optical disc is divided into a plurality of zones which each include a plurality of adjacent tracks, and includes sector information showing data assignment for sectors on the optical disc,the recording area of the optical disc is divided into a plurality of 2 KB sectors, with each set of 16 consecutive sectors forming one ECC block,the video object is composed of a plurality of packs, each pack having a size of 2 KB, andthe minimum size is the number of ECC blocks which is represented as ""N.sub.-- ec c"" in the following formula:N ecc=Vo*Tj/((16*8*2048)*(1-Vo/Vr)),where ""Tj"" represents a maximum jump time of an optical pickup of a reproduction apparatus, ""Vr"" represents an input transfer rate (Mbps) of a track buffer of the reproduction apparatus, and ""Vo"" represents an effective output transfer rate (Mbps) of the track buffer,said optical disc recording apparatus comprising:a reading means for reading the sector information from the optical disc;a recording means for recording the video object onto the optical disc; anda control means for controlling the reading means and the recording means:detecting at least one series of consecutive unassigned sectors on the optical disc by referring to the read sector information, each series having a total size greater than a minimum size, the minimum size corresponding to a data amount that ensures uninterrupted reproduction of the video object andcontrolling the recording means to record the video object into the detected series.
