ABSTRACT:
In a data recording method which uses a recording format having first and second preamble fields each for executing bit synchronism, first and second synchronization pattern fields each for defining the head position of a data stream, and a data field for recording the data stream, the first preamble field, the first synchronization pattern field, the second preamble field and the second synchronization pattern field are arranged in sequence in the order stated, and the first and second synchronization pattern fields are arranged in advance of the data stream. Also, the data stream is divided into a plurality of data blocks, and a re-synchronization pattern field having the same pattern as that of the synchronization pattern field is arranged just in advance of each of the data blocks.
