A method for reducing data access time in a disk drive. The disk drive
includes an actuator and a servo controller. The servo controller commands
the actuator to perform a seek from a current position to a target
position using a profile of command effort to the actuator. The profile
comprises an acceleration profile and a deceleration profile. In one
aspect, the method includes defining a read profile for a seek used to
position the actuator to execute a read command. A write profile is
defined for a seek used to position the actuator to execute a write
command, the write profile being different from the read profile for a
respective seek distance. The read and write seeks are performed using the
read profile and the write profile. The average time required for
performing a seek command is reduced as a result of the difference between
the read profiles and the write profiles.
