Abstract
A data storage device is disclosed comprising a head actuated over a disk, wherein the head comprises a laser configured to heat the disk while writing data to the disk. While writing data to the disk, an updated power setting for the laser is stored in a staging register, and during a non-write mode, the updated power setting is transferred from the staging register to an operating register in order to update an operating power for the laser.
