A modified cosine equalization effective for equalizing both amplitude and phase has been developed with a simple circuit. It slims asymmetrical read-back waveforms in digital magnetic recording devices more effectively than without phase equalization.

A new write current equalization technique achieved by means of a simple write data operation is presented. This technique nearly doubles the write channel speed and makes it possible to realize a high data transfer rate read/write channel in digital magnetic recording.
