Abstract: A unitary magnetic transducer and suspension assembly suitable for use in both contact recording and in winchester-type applications is described. A generally rectangular elongate flat suspension member includes a ring-type inductive read/write transducer formed integrally with the suspension member and is embedded in one end of the suspension member. The ring-type inductive transducer is suitable for horizontal recording applications. The transducer magnetic poletips and magnetic gap are formed and positioned such that the poletips and gap are essentially co-planar with the air bearing surface of a slider-shaped protrusion extending from the lower surface of the end of the suspension member adjacent a moving media during operation. The air bearing surface presented to the disk has most of its area covered with a wear layer to minimize wear of the slider surface and poletips.

Abstract: The positioner comprises a fixed frame (1) from which extends a first pair of parallel piezoelectric benders ("bimorphs") (2, 3) which carry an intermediate frame (4). Actuation of the bimorphs (2, 3) causes lateral translation of the intermediate frame (4) with respect to the fixed frame with the bimorphs (2, 3) forming the flexible sides of a parallelogram.Attached to the intermediate frame (4) is a second pair of bimorphs (12, 13) which extend in a direction orthogonal to the direction of the first pair of bimorphs (2, 3) thus permitting a support frame (14) to exercise a deflection in a direction orthogonal with respect to the movement of the intermediate frame (4).The bimorphs used consist of one or two piezoelectric elements carrying two or more electrodes on either side the proper actuation of which causes the benders to bend with parallel end surfaces at all times.
