摘要： A differential read head comprises one tri-layer reader or a plurality of tri-layer readers operating in a current perpendicular to plane (CPP) mode. The tri-layer readers each comprise a first free layer, a second free layer, and a nonmagnetic layer positioned therebetween. A nonmagnetic spacer is positioned between the plurality of tri-layer readers for electrically connecting the plurality of tri-layer readers in series such that a single CPP sense current representing a differential signal flows serially through the read head. With a single tri-layer reader, the free layers are spaced by a width substantially similar to the transition width of the magnetic medium.

摘要： An apparatus and associated method for a multi-bit memory capable of being selected with a magnetic layer. Various embodiments of the present invention are generally directed to a first selection layer with a low coercivity that is disposed between first and second storage layers that each have a high coercivity. In response to magnetic saturation of the first selection layer, programming of a logical state to the second storage layer is allowed.

摘要： The present invention relates to a head having an air bearing surface for confronting the surface of a storage medium. The head includes a first pole that is spaced apart from a second pole. At least one non-magnetic spacer is positioned between the first pole and the second pole such that the first pole is magnetically decoupled from the second pole. In a further aspect, one or both of the first pole and the second pole can be elliptical in shape.

摘要： A beveled writing pole includes a top portion, a beveled portion, and a throat portion. The top portion has an end that defines a writing pole tip. The beveled portion adjoins the top portion and has a bevel that extends from the writing pole tip and increases a thickness of the writing pole proximate the pole tip. The throat portion is formed of the top and beveled portions and has tapered sides that extend from the writing pole tip and increase a width of the writing pole proximate the writing pole tip. A method of forming the beveled writing pole is also presented.
