摘要： 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.

The display apparatus includes an image signal processing circuit which performs sub field conversion processing on an input image signal, a computational processing circuit which arranges address data of at least one lower sub field of an image displayed on the display unit identical in plural lines, and a drive circuit which addresses and illuminates pixels of the display unit based on the outputs of the input signal processing circuit and the computational processing circuit. An image corresponding to the input image signal is displayed by driving the display unit with the drive circuit when the computational processing circuit performs addressing of the at least one lower sub field simultaneously in plural lines and address periods which select the illuminated pixels of said display unit are shortened.
