Abstract:
A magnetic disk drive apparatus, comprising:a magnetic disk having a storage surface and a plurality of data tracks arranged concentrically on said storage surface;a magnetoresistive head located movably adjacent to said storage surface and including a magnetoresistive sensor and a write pole separated from said magnetoresistive sensor by a predetermined distance, with said magnetoresistive head having associated therewith for each one of said plurality of data tracks a track shift corresponding to said data track;a memory storing program data representative of an execution program, with said program data including data representative of an initialization routine for controlling said magnetoresistive head to write a plurality of additional burst signals for a selected one of said plurality of data tracks, with said additional burst signals indicating an optimal off-track distance for positioning said magnetoresistive head to compensate for said track shift corresponding to said data track; anda microcontroller in communication with said memory and adapted to control a radial position of said magnetoresistive head with respect to said storage surface in accordance with said execution program.
