Abstract
A data storage device is disclosed comprising a head actuated over a disk comprising a plurality of tracks. An operating seek time profile is generated as a function of a base seek time profile, wherein the seek time profiles define a seek time to seek the head radially over the disk by a seek length. A seek operation is executed to seek the head by a target seek length by at least generating a target seek time based on the target seek length and the operating seek time profile, and seeking the head the target seek length based on the target seek time.
Claims14
A data storage device comprising:
- a disk comprising a plurality of tracks;
- a head actuated over the disk;
- and
- control circuitry configured to:
- generate an operating seek time profile as a function of a base seek time profile, wherein the seek time profiles define a seek time to seek the head radially over the disk by a seek length;
- and
- execute a seek operation to seek the head by a target seek length by at least:
- generating a target seek time based on the target seek length and the operating seek time profile;
- and
- seeking the head the target seek length based on the target seek time.
A method of operating a data storage device, the method comprising:
- generating an operating seek time profile as a function of a base seek time profile, wherein the seek time profiles define a seek time to seek a head radially over a disk by a seek length;
- and
- executing a seek operation to seek the head by a target seek length by at least:
- generating a target seek time based on the target seek length and the operating seek time profile;
- and
- seeking the head the target seek length based on the target seek time.
