FIELD: magnetic recording engineering. SUBSTANCE: method involves shaping of write signals for each block in the form of series of marker and data sections of sine-wave signals with zero DC component attained coarsely by interchanging code groups in data blocks and code-modulating number of interchanging procedures for lengths of one of marker half-cycle sections of block recording signal and finely, by respectively reducing amplitude of same marker of half-cycle section. EFFECT: improved characteristics of data block recording density on magnetic medium and improved accuracy of identification of read-out block signals. |
