Abstract:
A process for inhibiting write operations in a disk drive system including a disk having a plurality of tracks formed thereon, and a read/write head, said process being performed during a head settling period following a track seek operation, said process comprising the steps of:during each of a first plurality of sampling intervals transpiring during a first time period,determining a present position value indicative of the position of the head relative to the center of a target track during a present sampling interval,determining a predicted position value indicative of the position of said head relative to said center of said target track during a subsequent sampling interval,determining whether or not said present position value is within a first error margin from a center value indicative of said center of said target track,determining whether or not said predicted position value is within said first error margin from said center value, andif said present position value and said predicted position value are both within said first error margin from said center value, enabling the write operations.
