<p>WRITE DATA COMPENSATING CIRCUIT IN MAGNETIC RECORDER A write data compensating circuit in a magnetic recorder comprising a shifting circuit for shifting binary data in time series and producing front, present, and rear signals regarding the binary data, and a combination logic circuit for effecting a preshift to the present signal provided as write data in accordance with a pattern of the front, present, and rear signals. The combination logic circuit is comprised of a first circuit operative to discriminate a pitch of each two adjacent inversions of magnetization to be created by the write data and a second circuit operative to adjust each pulse width of the write data based on an analysis by the first circuit.</p> |
