Abstract
According to an aspect of the present disclosure, a system for correcting for DC characteristics of a magnetic recording system includes: circuitry implementing at least a portion of a write channel of the magnetic recording system; and circuitry configured to process output data of the write channel circuitry in accordance with a read channel of the magnetic recording system and repeatedly trigger re-writing through the write channel circuitry using different ones of a plurality of available data scramblings until a measured baseline wander exceeds a target threshold.
