ABSTRACT:
High track density multitrack magnetic heads are batch-fabricated from a stack of wafers which are photolithographically processed to provide lands and grooves on the wafers. Thin magnetic films are deposited in the grooves; and coils respectively inductively cooperative with the films are photolithographically formed about the films, the lands serving both to provide track-to-track spacing and to protect the magnetic films from magnetostriction-producing stress.
