Magnetic head support arm

摘要

An improved magnetic head support mechanism intended for causing a magnetic head to float over a magnetic recording medium, comprises a spring member for retaining the magnetic head and a loading beam member provided with flanged portions along both longitudinal sides thereof and connected to the spring member at one end thereof and coupled to a shifting mechanism at the other end thereof and capable of giving the magnetic head an urging force to act on the magnetic recording medium. The loading beam member is penetratingly formed with at least one passing hole which permits the passing therethrough of an air stream generated by the rotational movements of the magnetic recording medium when the magnetic head is floating, so that it is possible to reduce the exciting force acting on the loading beam member and to thereby obtain the stabilized floating of the magnetic head.
