Abstract

PURPOSE: To enable the recognition of blocks to be performed accurately even if interblock gaps are shortened by adding date block recognition numbers to respective data blocks.
CONSTITUTION: Each data block is formed by data synchronizing parts 6, 10, data part 8, and the block recognition numbers 7, 9 as part of the data at the leading and trailing ends of the data part 8. At the numbers 7, 9 and the interblock gap between the blocks is made shorter and even. Hence, the data capacity of magnetic tapes may be well increased
