Abstract
A hard disk drive with a controller that controls a movement of a head relative to a disk. The controller causes the head to avoid a defect on the disk during a seek routine. The location of the defect is previously identified and stored in the drive. The drive may create a 'no-fly' zone about the defect to insure no contact with the head. The no-fly zone can be avoided by delaying the start of a seek routine, varying the displacement profile of the head or other techniques.
