Abstract:
1. A control apparatus that is included in a recording apparatus together with a reading means for reading the sector information from an optical disc, a track buffer, and a recording means for recording video objects on an optical disc, wherein a recording area of the optical disc is divided into a plurality of sectors, with each set of N_sec consecutive sectors forming one ECC block, each sector having a size of S_size bytes, each video object is composed of a plurality of packs, each pack having a size of S_size bytes, recording sector information recorded on the optical disc shows data assignment for sectors on the optical disc, and the minimum size is the number of ECC blocks which is represented as “N_ecc” in the following formula: 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 control apparatus comprising: 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; and means for controlling a recording means to record the video object including S_size-byte packs onto the detected series of consecutive unassigned sectors.
