摘要： A longitudinal recording head (50, 56, 60) for use with magnetic recording media includes a non-uniform gap (54, 59, 64) between first (51, 57, 61) and second magnetic (52, 58, 62) poles which focuses magnetic flux onto a small area of the magnetic recording medium. The non-uniform gap is preferably in the form of a cavity that is contoured to produce the desired flux pattern. Longitudinal recording heads incorporating the non-uniform gap are capable of improved recording densities.

摘要： A method of making c-axis perpendicularly oriented barium hexaferrite thin films by the crystallization of amorphous barium hexaferrite on a platinum underlayer is provided. Using a thin underlayer of platinum, barium hexaferrite films can be deposited by conventional rf diode or magnetron sputtering. Such deposition may be performed at room temperature, after which excellent c-axis perpendicular orientation can be achieved by rapid ex-situ annealing. The c-axis perpendicular orientation can also be achieved through in-situ annealing.

摘要： The present disclosure is directed to a micromachined rotary actuator constructed of a central portion and an outer portion at least partially surrounding the central portion and separated from the central portion by an in-plane gap. A plurality of arms are each connected at one end to the central portion and at another end to the outer portion so as to span the in-plane gap. The arms are constructed of a plurality of horizontally stacked materials positioned to enable the arms to bend in-plane when heated. Conductors are positioned within the actuator for heating the arms. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
