ABSTRACT:
A digital signal recording method of the present invention for recording data divided into at least two segments in a recording track on a magnetic tape with a magnetic head mounted onto a rotational drum, includes the steps of: recording a first segment; recording a preamble having a length PR in a recording track direction so that the preamble is adjacent to a front edge of the first segment; recording a postamble having a length PO in the recording track direction so that the postamble is adjacent to a back edge of the first segment; and recording a second segment after the step of recording the first segment, wherein a relation PR=PO=G is substantially satisfied where "G" is a length of a gap in the recording track direction between the first segment and the segment.
