Abstract
Several readings of an actuator's location are taken with a given head while urging the actuator against a mechanical stop, which acts as a guide. These readings are useful, for example, for estimating certain offsets or for determining a nominal track range for a data surface.
Claims17
A method comprising steps of:
- (a) positioning a data surface adjacent a head mounted onto an actuator;
- (b) while urging the actuator into a stationary lateral position against a stop, sensing a plurality of partly accessible tracks on the surface;
- and
- (c) defining an accessible track range for the surface that includes fully accessible tracks on the surface and excludes the sensed plurality of partly accessible tracks.

A method comprising:
- (a) of urging an actuator against a stop while identifying each of several tracks at a common, stationary lateral actuator position using a head supported by the actuator;
- and
- (b) defining an accessible track range for the surface partly based on a laterally-most extreme track that is identified and fully accessible during step (a).
A method comprising steps of:
- (a) positioning a data surface adjacent a head mounted onto an actuator;
- (b) sensing several lateral track identifiers while urging the actuator laterally against a stop at a fixed, common actuator position;
- and
- (c) determining an accessible track range for the surface partly based on the several lateral track identifiers.
