Multi-track servo recording head, resultant media containing pre-recorded servo track, and servo controlled head positioning system.

摘要

This invention relates to a magnetic recording head assembly 10 and method enabling an end user to record a unique servo control track on a magnetic recording tape. The invented head assembly includes, in addition to a plurality of sets of read/write transducers, a servo write head having an extended transverse width for uniformly recording a servo signal across the width of a servo track section, and a servo erase head having a plurality of alternating erasing and non-erasing sections adapted to controllably erase portions of the previously recorded servo signal, resulting in unique servo control tracks which are subsequently read in a servo system to control the transverse position of read/write head assembly. <IMAGE>
