Abstract: A module according to one embodiment includes a plurality of transducers; a tape bearing surface having a transducer region aligned with the transducers in a tape travel direction, and outer regions flanking the transducer region in a direction perpendicular to the tape travel direction; a first coating on the transducer region of the tape bearing surface; and a second coating on at least one of the outer regions of the tape bearing surface, the second coating being different than the first coating.

Abstract: A magnetic head that includes: a slider having a leading edge and a trailing edge; and a transducer, the transducer formed on the trailing edge of the slider and the transducer including: a substrate; a basecoat positioned adjacent the substrate, wherein the basecoat includes a material having a Young's modulus that is less than that of alumina and a coefficient of thermal expansion that is less than that of alumina; a reader; a writer; a heater; and an overcoat encasing at least a portion of the transducer, wherein the overcoat includes a material having a Young's modulus that is less than that of alumina and a coefficient of thermal expansion that is less than that of alumina.

Abstract: Provided is a thin-film magnetic head, in which the magnetic spacing can be controlled appropriately, regardless of the presence of the variation in height of the medium-opposed surface of the closure. The thin-film magnetic head includes: at least one head element formed on or above an element-formation surface of a substrate, for reading data from a magnetic recording medium and/or writing data to a magnetic recording medium; an overcoat layer formed on the element-formation surface so as to cover the at least one head element; and at least one closure adhered to at least a portion of an upper surface of the overcoat layer. Here, at least one of the at least one closure includes at least one element for adjusting the height of a medium-opposed surface of the closure. The element is preferably a heating element provided within the closure.

Abstract: A thin-film magnetic head according to the present invention comprises: a substrate; at least one magnetic head element formed on the substrate; an overcoat multilayer composed of a plurality of overcoat layers, formed on the substrate so as to cover the at least one magnetic head element; and at least one heating element to be heated at least during operation of the at least one magnetic head element, the at least one heating element provided in the overcoat multilayer, and a coefficient of thermal expansion of an overcoat layer located farthest from the substrate in the overcoat multilayer being smaller than a coefficient of thermal expansion of an overcoat layer located closest to the substrate in the overcoat multilayer.

Abstract: A magnetic recording medium according to the present invention includes a nonmagnetic base material, a soft magnetic under layer, an interlayer, a recording layer and a protective layer, which are stacked over the base material. The soft magnetic under layer is formed of a lower soft magnetic layer, a magnetic domain control layer (or a nonmagnetic layer) and an upper soft magnetic layer. The lower and upper soft magnetic layers are each made of a material amorphized by adding at least one of zirconium (Zr) and tantalum (Ta) to an iron-cobalt (Fe—Co) alloy which is composed to form a body-centered cubic (bcc) structure.
