Abstract:
In a disk drive including at least one data disk having multiple concentric data tracks thereon for storing data, and a transducer radially moveable relative to said data tracks by an actuator during a seek operation from a starting track to a destination track in response to controlled application of current to the actuator based on a seek profile, a method for determining the seek profile for one or more seek operations, comprising the steps of:(a) for a seek operation from a starting track to a destination track, determining an actuator current control value such that in response to controlled application of current to the actuator as a function of the current control value the acoustic output from the disk drive is at or below a desirable level; and (b) storing the current control value in a memory device in relation to the seek length and location, wherein the seek length represents the distance between the starting and destination tracks, and the seek location represents the radial locations of the starting and destination tracks; wherein the current control value can thereafter be used to perform seek operation in the disk drive.
