Recording/reproducing apparatus for recording and reproducing multiple kinds of digital signals having different data amounts per unit time

摘要

The method and apparatus records/reproduces multiple kinds of digital signals having different data amounts per unit time on a recording medium. The multiple kinds of digital signals are organized into a plurality of blocks. At least two of the multiple kinds of digital signals are organized into blocks having different lengths. A synchronizing signal is appended to each of the plurality of blocks. The synchronizing signal identifies a length of each of the plurality of blocks. This method an apparatus increase the recording rate, and is therefore suitable for higher density recording. In reproduction, synchronization protection is performed for variable synchronization periods based on the length of the blocks being reproduced.
