Abstract
A disk drive selectively provides either higher-performance seek operations or reduced-audible noise while effecting seek operations. A higher performance seek operating mode and a quiet seek operating mode are defined. The servo controller controls seek operations and may store and/or access a number of seek profiles including a first seek profile defined to provide relatively short average seek times and a second seek profile defined to provide quieter operation on average in comparison with the first seek profile. The servo controller and associated circuitry causes the drive to effect a seek operation subject to the first seek profile in response to the higher performance seek operating mode and effect a seek subject to the second seek profile in response to the quiet seek operating mode. The differing modes of operation may be invoked automatically, manually and/or adaptively, based upon a command from a host, input from a user, or some signal generated from within or without the drive or device incorporating the drive.
