Magnetic tape format for recording digital picture data

摘要

In a magnetic tape on which digital picture data is recorded along helical tracks formed on the tape, the format used therefore is such that: each picture data segment consisting of picture data of one frame or one field is recorded in a plurality of consecutive tracks, the picture data segments are grouped into blocks, each block comprising a plurality of picture data segments, block numbers identifying the respective blocks are recorded in the tracks in the respective blocks, and picture numbers identifying the respective picture data segments within each block are written in the tracks which also record the picture data segments.
