Abstract
Dispersing and reducing wear of a rotatable disc surface using a stimulated take off process to accelerate formation of an air bearing between a read/write head and a non-textured circumferential landing zone of a rotatable disc surface of a disc drive by accelerating the non-textured circumferential landing zone of the rotatable disc surface to a rotational operating speed through application of a current to a spindle motor assembly securing the rotatable disc surface while stimulating a head stack assembly with a reciprocating lateral displacement effectuating a tracing of a radially varying path across and around the circumferential landing zone of the rotatable disc surface by the read/write head accelerating formation of the air bearing between the read/write head and a non-textured circumferential landing zone, thereby dispersing and reducing wear of the rotatable disc surface.
