Patent ID: 7103262

Claim:
An optical disc recording apparatus for recording video objects on an optical disc, wherein a recording area of the optical disc is divided into a plurality of blocks, each of which is composed of a set of N_sec consecutive sectors, each sector having a size of S_size bytes, the optical disc records sector information showing data assignment for each sector on the optical disc, said optical disc recording apparatus comprising: a reading unit operable to read the sector information from the optical disc; a detecting unit operable to detect a series of consecutive unassigned sectors on the optical disc by referring to the read sector information, a total size of the series being no smaller than a predetermined size that corresponds to a data amount that ensures the reproduction apparatus for uninterrupted reproduction of the video object; and a recording unit operable to divide and record a video object onto two or more series of consecutive unassigned sectors detected by the detecting unit, and the predetermined size is the number of blocks which is represented as “N” in the following formula: N=dN+Vo *( Tj+Ts )/(( N _sec*8 *S _size)*(1− Vo/Vr )), where “dN” is a number of blocks, in the series of consecutive unassigned sectors, that include defective sectors, “Tj” represents a maximum jump time of an optical pickup of a reproduction apparatus, “Ts” represents a time taken by the optical pickup to skip dN blocks, “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.
