An architecture to compensate for the non-linear effects of magnetic media, such as magnetic disk drives, that distorts data transitions when data is written to the media and in which the non-linear distortion is data sequence dependent. In one technique a circuit is used to alter the data transitions to cancel the effects of the transition distortion. The circuit employs selected delays that that based on the data sequence to adjust the transition edge of bits of the data to provide the pre-compensation before data is written to the disk.
