Abstract
An apparatus includes: a media; a head configured to write data on the media; a read channel, coupled to the head, configured to detect servo data from the media; and control circuitry, coupled to the read channel, configured to: generate a position error signal (PES), associated with a write operation of an aggressor track, from the servo data, compare a first threshold to the PES for detecting a write unsafe condition, compare a second threshold, within the first threshold, to the PES for detecting a write squeeze condition, and control a refresh operation of a victim track based on at least one of the comparisons.
