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

A recording/reproducing apparatus for recording and reproducing multiple kinds of digital signals having different data amounts per unit time on a recording medium, comprising:

• blocking means for organizing said multiple kinds of digital signals into a plurality of blocks, at least two of said multiple kinds of digital signals being organized into blocks having different lengths, and for appending a synchronizing signal to each of said plurality of blocks, said synchronizing signal identifying a length of each of said plurality of blocks;
• recording means for recording the organized plurality of blocks on one track on the recording medium;
• reproducing means for reproducing said plurality of blocks from said recording medium;
• and
• synchronization protecting means for detecting said synchronization signal for each of aid plurality of blocks output by said reproducing means, and for performing synchronization protection for a variable protection period for said plurality of blocks based on said synchronization signal such that said synchronization protecting means sets said variable protection period for each of said plurality of blocks based on the length of each of said plurality of blocks.

• blocking means for organizing said multiple kinds of digital signals into a plurality of blocks, at least two of said multiple kinds of digital signals being organized into blocks having different lengths, for organizing said multiple kinds of digital signals into said plurality of blocks of different lengths such that a length of each of said plurality of blocks generally corresponds to a data amount per unit time of a corresponding one of said multiple kinds of digital signals, and for appending a synchronizing signal to each of said plurality of blocks, said synchronizing signal identifying a length of each of said plurality of blocks and identifying to which of said multiple kinds of digital signals each of said plurality of blocks corresponds;
• recording means for recording the organized plurality of blocks on one track on the recording medium;
• reproducing means for reproducing said plurality of blocks from said recording medium;
• and
• synchronization protecting means for detecting said synchronization signal for each of said plurality of blocks output by said reproducing means, and for setting a variable protection period for each of said plurality of blocks based on the length of each of said plurality of blocks, said synchronization protection means allowing sid recording/reproducing apparatus to accommodate blocks of different lengths within the same track .
