Optical disc recording apparatus, computer-readable recording medium recording a file management program, and optical disc

An optical disc recording method 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 showing 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:
• N—ecc=Vo*Tj/((N_sec*8*S_size)*(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 method comprising:
• a reading step for reading the sector information from the optical disc;
• a detecting step 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
• a recording step for recording the video object including S_size-byte packs onto the detected series of consecutive unassigned sectors.
