摘要： A flying-type composite magnetic head includes a slider made of a non-magnetic ceramic and having side rails extending longitudinally on both lateral sides of the head; a slit extending longitudinally in one of the side rails; and a magnetic core constituted by a pair of core pieces bonded to each other with a first glass and fixed in the slit with a second glass on both sides of the core. At least one of the opposing surfaces of the core pieces is formed with an Fe-Al-Si thin layer and the opposing surfaces of the core pieces constitute a magnetic gap of the magnetic core. Gaps formed on both sides of the magnetic core in a region exposed to an air-bearing surface of the head are filled with the second glass to improve the flatness of the air-bearing surface of the head.

摘要： A magnetic head carries out at least one of a recording, reproduction and erasure of an information on and/or from a magnetic recording medium by making sliding contact with the magnetic recording medium. The magnetic head comprises a first slider having a first surface which confronts the magnetic recording medium, a second slider having a second surface which confronts the magnetic recording medium and a contact portion for making sliding contact with the recording medium, and a magnetic head part sandwiched between the first and second sliders for carrying out at least one of the recording, reproduction and erasure of the information on and/or from the recording medium. The magnetic head part has a sliding contact surface for making sliding contact with the magnetic recording medium, and this magnetic head part projects from the first and second surfaces of the first and second sliders so that the sliding contact surface approximately coincides with the contact surface of the second slider.

摘要： A floating type magnetic head includes a magnetic core which is secured to a slider. The magnetic core is secured to the slider by glass or a synthetic resin on the rail surface side. It is secured to the slider on the other side by heating and melting the glass rod placed on a groove which is provided on a wiring groove of the slider for receiving the glass rod, whereby the magnetic core is securely fixed to the slider, which leads to the stabilization of the properties of the head and the improvement of the reliability.

摘要： A magnetic head having a central read/write core and a pair of erase cores is assembled with a leaf spring having corresponding slots for the cores. The leaf spring has a pair of clip arms at each end. The leaf spring with the assembled magnetic cores is fitted on an insulating holder case which has grooves for receiving the clip arms. The cores can be assembled more readily on the leaf spring than on the holder case, thus facilitating the assembly process and miniaturization of the magnetic head.

摘要： A semi self-loading air bearing ferrite slider assembly has a tapered leading surface portion extending from a cross rail from which side rails and a middle rail extend rearwardly. The middle rail progressively narrows to form the transducer portion where it extends across the gap between the body portion and core piece near the trailing end of the rail. Etched surfaces between the middle rail and the side rails provides subambient pressure during operation when the slider is in flight whereby the balance between the repelling air bearing surface and attraction of the subambient pressure areas supplements the stabilizing force of the load arm.

摘要： A magnetic head assembly and the method of manufacture therefor is disclosed which includes a housing having long and short body portions and a magnetic transducer comprising first and second core portions that are clamped in the respective body portions. The body portions are made of a nonmagnetic elastic material and include core-gripping surfaces defined by aligned slots cut through respective mating surfaces of the body portions. Prior to assembly, the body portions are permanently deformed by applying forces that exceed the elastic limit of the body material whereby the core-gripping surfaces are spaced apart by a distance less than the thickness of the core portions. Thereafter, the coregripping surfaces are forced apart to receive the respective core portions. When the forces are released, the core-gripping surfaces spring back to tightly clamp the core in the slots.
