Mechanism for adjusting magnetic head

摘要

A mechanism for adjusting magnetic head azimuth comprises a base plate carrying a magnetic head thereon, and this base plate is supported at two portions close to its both ends above a chassis. At one of the two supporting portions is provided an adjusting screw and a coil spring so that the base plate is upwardly biased by the coil spring in the same manner as in conventional arrangements. At the other supporting portion is provided a stationary supporting leg interposed between the lower surface of the base plate and the chassis where the base plate is screwed to the supporting leg having a generally rectangular flat top end defined by two straight parallel edges. One of the straight edges corresponds to a radial line passing through a center screw hole made in the supporting leg, and these straight parallel edges are arranged to be parallel to the center axis of the magnetic head. Since the base plate is always in contact with at least one of the straight parallel edges, it is prevented from being inclined in undesirable directions. As a result, the plane of the base plate is always normal to the magnetic recording tape irrespective of the degree and direction of possible azimuth adjustment.
