Abstract:
1. An AV data recording apparatus comprising a PES (Packetized Elementary Stream) stream assembling section to divide an audio signal and a video signal into PES packets and to assemble a plurality of the PES packets of a fixed length as one PES stream, and a recording section to record the PES stream in a plurality of logical blocks on a recording medium; the size of the PES packet of a fixed length having a non-integral multiple relationship with that of the logical block; the recording section comprising a logical block managing section to manage whether a logical block on the recording medium is used or not, a continuous data area detecting section to detect a continuous data area that ensures realtime continuous reproduction of the audio signal and the video signal, and a recording control section to determine a logical block number of the continuous data area on which the PES stream is to be recorded; wherein the PES stream is recorded continuously without providing any spacing in the plural continuous data areas detected by the continuous data area detecting section.
