Abstract: 0 In a magnetic information storage device of the type having a slider which moves relative to a magnetic recording medium such as a disk, the slider has a non-rectangularly shaped air bearing surface that provides the slider with a high degree of stability. The non-rectangular shape is preferably either a triangle or a trapezium. The non-rectangularly shaped slider includes a tapered leading edge and a flat vertical surface as its trailing edge. A conventional thin film head element can be deposited on the vertical surface, if the slider is fabricated from ceramic material, or a conventional head element having a wound coil can be disposed on the vertical surface, if the slider is fabricated from ferrite material.

Abstract: @ A magnetic recording and/or reproducing element (31) comprises a main element body (40), and windings wound around the main element body. The main element body has a pair of extremely thin layers (43, 44) made from a ferromagnetic material, and the extremely thin layers oppose each other at respective edges thereof so as to constitute a gap 145). Each of the thin layers is sandwiched between a pair of support members (46-49) which are made from a non-magnetic and abrasion proof material. A contact surface (56) is formed on a vertex part of the main element body, for making contact with a magnetic recording medium (22) so as to record and/or reproduce a signal on and/or from the magnetic recording medium. The main element body has one or a plurality of side surfaces (52-55) which form a predetermined angle with respect to the contact surface and define the peripheral edge of the contact surface so that the contact surface has a predetermined shape with an extremely small area and has the gap at an approximate center of the predetermined shape.

Abstract: A thin-film head has patterned pole tips (68) and a smooth interface surface topography (70) which eliminates the accumulation of foreign material around the pole tips (68). The patterned pole tips (68) are formed by removing material to obtain a desired pole tip shape. Fill material is added and reduced to produce a smooth surface topography (70).

Abstract: Method of manufacturing a magnetic head having a head face (5) and a layer structure with a transducing element (E) and a flux-guiding element (19a) terminating in the head face. The head face is provided with a wear-resistant layer (31) having a maximum thickness of 60 nm for forming a contact face (33). To improve the wear resistance, a bundle of ions is directed onto the wear-resistant layer, while ions are implanted in the wear-resistant layer until an implantation dose of between 10 ions/cm and 10 ions/cm is reached.

Abstract: A particularized cross section for a magnetic recording (16) head provides a constant area wear profile for cooperating magnetic tape (18). The constant area wear profile results from the ''combined'' use of a common radius of curvature for both the natural bending radius of the tape (RB) as well as the tape-contacting surface of the head (RH), taken together with the requirement that the leading and trailing medium-contacting parts (20, 22) of the head (16) form air-skiving edges which are essentially parallel to the force- (or pressure-) direction (23) associated with the tape-contacting interface.

Abstract: The invention is a self-cleaning head assembly characterized by one or more raised head islands (20) with convex top surfaces (21) and sloped sides (23, 24), and designed to be used with a recording medium (10) which wraps each island. The machined radius of curvature of the top surface is not less than half the natural curvature of the tape, and the running radius of the head is approximately equal to the natural curvature of the medium. A steep angle of approach (Φ) between tape and head provides cleaning action, while the small top surface reduces errors due to lift-off and provides superior electrical contact.
