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 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, the optical disc has sector information recorded thereon showing data assignment for sectors on the optical disc, and the minimum size is the number of ECC blocks which is represented as â€œN_eccâ€  in the following formula: Nâ€”ecc&gE;dNâ€”ecc+Vo*(Tj+Ts)/((N_sec*8*S_size)*(1âˆ’Vo/Vr)), where â€œdN_eccâ€  represents the number of ECC blocks which include defective sectors in a series of consecutive unassigned sectors, â€œTjâ€  represents a maximum jump time of an optical pickup of a reproduction apparatus, â€œTsâ€  represents a time period taken for the optical pickup to skip the dN_ecc ECC blocks, â€œVrâ€  represents an input transfer rate of a track buffer of the reproduction apparatus, and â€œVoâ€  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 the 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 means for recording the video object including S_size-byte packs onto the detected series of consecutive unassigned sectors.
