Abstract: A data storage medium has first and second data sectors of a track, a pre-servo gap being proximate the first data sector. The data storage medium also includes a servo wedge that stores servo data for the track. A start of the servo wedge is proximate to the pre-servo-gap and an end of the servo wedge is proximate to the second data sector. A repeatable runout field is included in the pre-servo gap.

Abstract: An apparatus includes a write element configured to apply a magnetic field to write data on a portion of a heat-assisted magnetic recording media in response to an energizing current. An energy source is configured to heat the portion of the media being magnetized by the write element. A preheat energizing current is applied to the write element during an interval before writing the data to the portion of the media. The preheat energizing current does not cause data to be written to the media and brings at least one of the write element and driver circuitry into thermal equilibrium prior to writing the data on the portion.
