    摘要： To reduce influence of errors on the outer periphery side of a multi-layer recording disc, a first shifted middle area is assured at a predetermined position nearer to the inner periphery side than the last position of layer on the outer periphery side of a single-sided, multi-layer recording disc, and a second shifted middle area is assured at the position of layer that opposes the shifted middle area assured on layer. A recording layer extending from layer to layer may be shifted in the first and second shifted middle areas, and an area in which errors relatively readily occur on the outer periphery side of the first and second shifted middle areas may not be used.

    摘要： This invention relates to a recording/reproduction system having a function of recording/reproducing video information with a GOP structure in the MPEG2 scheme on/from a disk. In this system, when a cut position designated by the user on the reproduction frame is set within the GOP, start picture data in the latter half of video data using the cut position as the reference position is set to I picture data. That is, when the picture data is of the B type, the CPU controls an encoder/decoder to change the picture data to I picture data. Accordingly, the latter half can be generated as reproducible video data.

    摘要： In a computer system having a recording/ reproducing device in which a DVD-RAM or the like is used as a recording medium, the CPU and the memory allocates logical blocks and record blocks, in multiple units of a common block for data to be written on a recording medium. The common blocks have a size of the least common multiple of the size of logic block and the size of record block, and the front of the allocated logical blocks coincides with the front of the allocated record blocks. The data is recorded on the recording medium by the recording/reproducing device. Hence, the data can be recorded in the most desirable manner even if the logical blocks and the record blocks defer in size.
