    摘要: A magnetic head comprising a magnetic core 1, a slider 2 constructed of a non-magnetic ceramic, a supporting plate 3 made of a metal which securely bonds the slider 2, and one or more grooves 4 formed in the surface of the supporting plate 3 which bonds the slider 2. The grooves 4 absorb or moderate warping stress exerted on the supporting plate 3 due to difference in the thermal expansion coefficients of the slider 2 and the supporting plate 3 to prevent warping deformation of the supporting plate 3, thus preventing distortion of the slider 2. This allows maintenance of the flatness of the top surface 2a of the slider 2, prevention of spacing loss, and recording and reproduction with a high degree of reliability.

    摘要: A magnetic head core slider including an air bearing and a core portion with a magnetic gap provided adjacent one of lengthwise opposite ends of the air bearing. A preliminary track is defined by preliminary width-defining grooves such that the preliminary track extends across the magnetic gap in the direction of extension of the air bearing, each groove having a depth larger than the depth of the magnetic gap. An effective track is defined by a pair of opposed final width-defining recesses formed adjacent to the magnetic gap such that the effective track extends across the magnetic gap in the direction of extension of the air bearing. The length and width of the effective track are smaller than those of the preliminary track, and the width of the effective track determines the nominal width of the magnetic gap. Each recess has a depth smaller than that of the preliminary width-defining grooves but larger than that of the magnetic gap. Also disclosed is a process of fabricating the head core slider.

    摘要: A magnetic head for writing and/or reading out data into and/or from a magnetic tape has surfaces defining a reference plane for determining a position of an edge of a traveling magnetic tape and defining an inclined plane for urging the magnetic tape to the reference plane, and a tape travel surface defined between the reference and inclined planes. A recess is formed at a portion of the tape travel surface extending along at least one edge of the magnetic tape.

    摘要: A magnetic disk device includes an arm disposed at a distance from a magnetic disk surface, a magnetic head support having a first end associated with the arm and having a second end extended toward the magnetic disk surface, a magnetic head provided on the second end of the magnetic head support, and an actuator for rotating the arm so as to cause the magnetic head to move toward or away from the magnetic disk surface. The magnetic head support has rigidity in a direction parallel to the magnetic disk surface and flexibility in a direction non-parallel to the magnetic disk surface over an area extending from the first end to the second end of the magnetic head support, and includes a gas pressure generating structure integral with a portion of the magnetic head support facing the magnetic disk surface for generating a gas pressure between the magnetic head support and the magnetic disk surface due to relative movement between the magnetic head support and the magnetic disk surface.

    摘要: A method of constructing a ferrite magnetic head that can be used for vertical recording. The head is created by first bonding a non-magnetic shoe to the legs of a C-Shaped magnetic core to create a block assembly. A pole surface of the block is then lapped and sputtered with a magnetic pole material. A layer of alumina is then sputtered onto the magnetic pole material. After sputtering, the block is ground to create air bearing grooves and a plurality of poles. The bearing surface of the block is then lapped to the apex of an oblique interface between the shoe and core to create the throat of the pole. The block is cut into individual transducer cores which are then wrapped with a wire coil and attached to a flexbeam.
