ABSTRACT:
A magnetic recording method for digital signals, and more particularly to a magnetic head driving current waveform wherein digital signals to be recorded on a magnetic tape at a high density have the waveform of the head driving current shaped in order to reduce the degradation of the waveform. That is, in a case where the period of the current reversal of the driving current is long and continues for at least 1.5 times the bit period, the amplitude of the current in the rise part of the wave is made small. The driving current of this waveform has a reduced waveform degradation, and the magnetic recording at the high density becomes possible.
