    摘要： To provide a magnetic recording medium manufacturing method capable of transferring a pattern that can serve as a source for forming anodized alumina-nanoholes with high precision and realizing high productivity, and a large-capacity magnetic recording medium capable of achieving high density recording. The method includes forming a metallic layer on a concavo-convex pattern formed on a surface of a mold; bonding a substrate using an adhesive to a surface of the metallic layer on the side opposite to the mold; separating the mold from the metallic layer; forming, through nanohole formation treatment, a porous layer in which a plurality of nanoholes are formed to orient in a direction substantially perpendicular to a substrate plane by using as a nanohole source a concavo-convex pattern which has been formed by transferring the concavo-convex pattern in the mold to the metallic layer; and charging a magnetic material inside the nanoholes.

The free magnetization layer includes CoMnAl. The diffusion prevention layer is provided between the non-magnetic metal layer and the free magnetization layer so as to prevent Mn included in the free magnetization layer from diffusing into the non-magnetic metal layer.

    摘要： An electrically conductive body is connected to an electromagnetic transducer film in a electromagnetic transducer element so as to form a path for current supplied to the electromagnetic transducer film. Heat is generated based on the electric resistance of the electromagnetic transducer film. A thermoelectric element such as a Peltier element is incorporated in the electrically conductive body. The thermoelectric element serves to absorb the heat. The supplied current is also utilized to drive the thermoelectric element. A wiring pattern and a power source dedicated to the thermoelectric element can be omitted in the electromagnetic transducer element. The electromagnetic transducer element is thus allowed to suppress rise in the temperature of the electromagnetic transducer film with a simple structure.

    摘要： A current-perpendicular-to-the-plane (CPP) structure magnetoresistive element includes an electrode layer contacting a magnetoresistive film. A low resistance region is defined to extend rearward along the boundary of the magnetoresistive film from the front end exposed at the medium-opposed surface of the head slider. A high resistance region is defined to extend rearward along the boundary from the rear end of the low resistance region. The high resistance region has a resistivity higher than that of the low resistance region. The high resistance region serves to restrict the path of a sensing current nearest to the medium-opposed surface. The sensing current is allowed to concentrate at a position closest to the medium-opposed surface in the magnetoresistive film. Magnetization sufficiently rotates in the magnetoresistive film near the medium-opposed surface. The CPP structure magnetoresistive element maintains a sufficient variation in the resistance. A sufficient sensitivity can be maintained.
