Abstract
Abstract In a data recording technique, a file for a computer system is arranged on a recording medium between TOC and video or audio data, thereby enabling the video or audio data to be read out at a high speed and reproduced either by the computer system or by a relatively inexpensive reproducing apparatus (e.g. CD or video CD player). Digital moving picture data and audio data are formed into packets and recorded as time division multiplexed bit streams, the bit streams being split in a self-complete manner, and with the split bit stream representing one program being recorded in a respective one of plural areas. Start access entry points of the programs also are recorded to establish self-complete positions of those programs.
