ABSTRACT:
An initialization for runout cancellation for a hard disk drive such as a Small Computer System Interface (SCSI) hard disk drive. The hard disk drive at a servo sample rate updates a set of state variables. At an index wedge the state variables are stored to a memory. Upon a command to perform a head switch the hard disk reads the previously stored state variables from the memory. The previously stored state variables are used to adjust the repeatable runout based on the location of a head relative to an index wedge.
