Abstract
Various illustrative aspects are directed to a data storage device, method, and one or more processing devices that are configured to: estimate access times of a plurality of access commands included in a command queue of a disk drive containing the one or more disks; adjust a respective one of the access times of a respective one of the access commands based on the respective one of the access commands satisfying one of one or more conditions that indicate an increased likelihood of performing a pre-heating operation to heat a laser diode associated with a head of the disk drive; and select one of the access commands as a next command for execution in the disk drive based on the access times.
