Patent ID: 6967811

Claim:
A disk drive comprising an actuator having a voice coil motor (VCM), a head mounted on the actuator, a disk comprising a plurality of tracks and a servo control system for moving the actuator to position the head over a track, the servo control system comprising: a first seek operating mode to move the actuator over a seek distance D in a seek time T 1 , using a first seek profile for minimizing T 1 and wherein for a first repetitive series of seeks over distance D, the servo control system would require a delay time T D between seeks to control temperature rise in the VCM; and a second seek operating mode to move the actuator over the seek distance D in a second seek time T 2 using a second seek profile for limiting the temperature rise in the VCM, wherein for a second repetitive series of seeks over the seek distance D, a time average T AVG of the T 2 seek times is substantially less than T 1 +T D .
