Abstract:
A data storage device and associated methods may provide at least a data storage medium that is separated from a heat assisted magnetic recording data writer and is connected to a controller. The controller can be configured to change a laser power of the heat assisted magnetic recording data writer in response to a tested bit error rate of a median data track of a plurality of adjacent data tracks reaching an identified threshold.
