Abstract
An offset from track center of data is determined in a data storage device. The data is written to a heat-assisted magnetic recording medium of the device, and the offset compensates for degradation of an optical component of a read/write head when writing the data. The offset is stored in a memory of the storage device. Using the offset, a track alignment is changed during subsequent writes via the read/write head.
