Abstract
Provided are a method, apparatus, and storage medium for controlling a track seek servo in a disk drive. Thus, a transducer is moved to a target track using a transformed Proximate-Time Optimal Servo (PTOS) velocity trajectory in which an acceleration duration is symmetrical to a deceleration duration in a track seek mode.
