摘要
A data storage device is disclosed comprising a disk comprising a plurality of data sectors and a plurality of servo sectors, and a head actuated over the disk, wherein the head comprises a laser configured to heat the disk while writing data to the disk. When the head is over a first data sector not being written, a first prelase bias is applied to the laser, and when the head is over a servo sector, a second, lower prelase bias is applied to the laser. When the head is over a second data sector being written, a write bias higher than the first prelase bias is applied to the laser.
