Abstract
At a storage section, picture information of intermediate resolution and picture information of low resolution are formed on the basis of picture information of high resolution which has been read out from a frame memory. These picture information are caused to undergo fixed length encoding at a compression/expansion circuit. These picture data of three kinds of resolutions which have been caused to undergo fixed length encoding are respectively recorded in the order of reproduction and continuously onto an optical disk having tri-sected recording areas for respective resolutions. Thus, it is sufficient to read out, from any one of the recording areas, picture data of resolution corresponding to the equipment which outputs picture data. In addition, since the picture data of respective resolutions are continuously recorded in the order of reproduction, the seek time is eliminated thereby contributing to realization of high reproduction speed.
