摘要： A method of generating a thin film for use in a spin valve of a magnetoresistive (MR) sensor having a nano-constricted spacer is provided. The bottom portion of the spin valve is deposited up to the pinned layer, a deposition chamber is provided, and the spacer layer is sputtered thereon. A main ion beam generates ions onto a composite surface including magnetic chips and insulator material. Simultaneously, an assisted ion beam provides ions directly to the substrate, thus improving the softness of the free layer and smoothness of the spacer layer. Neutralizers are also provided to prevent ion repulsion and improve ion beam focus. As a result, a thin film spacer can be formed, and the nano-constricted MR spin valve having low free layer coercivity and low interlayer coupling between the free layer and pinned layer is formed.

摘要： A heat assisted magnetic recording head is provided, which can prevent an effect of a heat in a laser diode when a magnetic recording region is heated by a heating laser beam and which can reduce its size and weight. In the heat assisted magnetic recording head, a recording magnetic pole, a magnetic recording element, a magnetic read element, an optical waveguide, and an irradiating optical waveguide are attached to a floating slider provided below a suspension. The laser diode is arranged on an opposite side of the suspension to the floating slider. The heating laser beam emitted from the laser diode is directed to the irradiating optical waveguide through the optical waveguide, so that a magnetic recording medium is irradiated with the heating laser beam exiting from the irradiating optical waveguide.

摘要： A reader of a magnetoresistive head includes a granular type free layer. The magnetoresistive head is for a current-perpendicular to plane type, and can be used in either a giant magnetoresistance (GMR) or ballistic magnetoresistance (BMR) scheme. The granular type free layer includes an insulating matrix, for example but not by way of limitation, Al2O3, and metal magnetic grains, for example but not by way of limitation, Ni, CoFe or NiFe. The metal grain size is about 10 to 30 nm, and the effect of having these grains interspersed in the insulative matrix is to provide a softer granular type free layer having a low magnetization. Accordingly, the granular type free layer of the present invention can be made thicker, on the order of about 5 to 10 nm, thus further improving overall thermal stability, reducing spin transfer effect and improving output read signal.

摘要： A method of fabricating a magnetic head device comprising a slider having a magnetic head element, a suspension structure made of a thin resilient material and having one end supporting the slider and the other end to be attached to another member, and a head IC chip. The head IC chip is mounted on the suspension structure so as to face a magnetic recording disc and at a position spaced from the slider-supporting one end of the suspension structure by an intervening portion of the suspension structure. The position is selected so that the intervening portion is effective to suppress a temperature increase in the head IC chip due to at least thermal conduction through the intervening portion.
