Abstract:

An improved head mounting structure which disposes a beam-like head support assembly for movement about a center hinge. A magnetic recording head is supported at an outer end of the head support beam assembly and a moving coil is supported at an opposite, inner end of the head support beam assembly. A motor drive assembly is disposed at the inner end of the head mounting structure to drive the coil and thereby induce corresponding movement in the head.
