Abstract:
A data storage device is disclosed comprising a head actuated over a disk comprising a plurality of tracks. A first degradation metric is maintained for a first segment of a first track, wherein the first degradation metric indicates a degree of degradation for data recorded in the first segment. The first degradation metric is processed to select an access command from a plurality of access commands including a read command to read the first segment. The selected access command is executed to access the disk.

Claim (Index 1):
A data storage device comprising:\n a disk comprising a plurality of tracks; a head actuated over the disk; and control circuitry configured to:\n maintain a first degradation metric for a first segment of a first track, wherein the first degradation metric indicates a degree of degradation for data recorded in the first segment; \n process the first degradation metric to select an access command from a plurality of access commands including a read command to read the data recorded in the first segment; \n execute the selected access command to access the disk; and \n force a refresh of the data recorded in the first segment when the first degradation metric exceeds a forced refresh threshold, \n wherein:\n the access command is selected based on a latency cost associated with executing the read command and a refresh benefit of refreshing the data recorded in the first segment; and \n the refresh benefit is based on the proximity of the first degradation metric to the forced refresh threshold.
