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

Abstract

An optical disc recording apparatus for recording a video object onto an optical disc. A recording area of the optical disc is divided into a plurality of zones which each include a plurality of adjacent tracks. The optical disc recording apparatus includes: a reading unit for reading from the optical disc the sector information showing data assignment for sectors on the optical disc; a recording unit for recording the video object onto the optical disc; and a control unit for controlling the reading unit and the recording unit. The control unit detects at least one series of consecutive unassigned sectors on the optical disc by referring to the read sector information. Each series has a total size greater than a minimum size and is located within a single zone. The minimum size corresponds to a data amount that ensures uninterrupted reproduction of the video object. The control unit also controls the recording unit to record the video object into the detected series.

         11 . A control apparatus that is included in a recording apparatus together with a reading unit for reading the sector information from an optical disc, a track buffer, and a recording unit 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” 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,   said control apparatus is 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 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   control the recording unit to record the video object including S size-byte packs onto the detected series of consecutive unassigned sectors.
