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 magnetic transducer (10) formed as a composite of three different materials for reproducing and/or recording signals with a magnetic medium, the transducer including first and second generally identical sections (12, 12'), which, when bonded together in opposing relation, form a transducer having aligned recesses (13, 13') in the outer edges and a formed winding window opening (19, 19') adjacent the pole tips, the window being arranged for receiving coil turns therethrough for providing the coil (32) on a line generally parallel to the tape contact surface of the transducer (10), the core legs (18, 18') being formed of two strips of Alfesil material, or the like, deposited or sputtered on the substrate. Each core section (12, 12') is formed as a portion of an elongate ferrite block substrate (20) with a thin cap of non-magnetic material (16, 16'), initially shaped to provide opposing elongate bonding notches (26, 28) on opposite edges of a common surface (22), and an intermediate winding groove (19b) in proximate relation to one of the notches. The winding groove preferably protrudes into the non-magnetic material to about half its depth. Thereafter the workpiece is provided with an array or a plurality of equally spaced V-shaped track width defining grooves (40a-40j) oriented in a direction perpendicular to the winding groove (19b), with the grooves defining pole edges having tapered side surfaces. A chrome adhesion layer is deposited on the grooved surface and into the winding groove, followed by a core layer of suitable magnetic material, such as Alfesil material which provides a pole material covering the edges as well as the tapered side surfaces. A chrome adhesion layer is applied to the Alfesil layer, followed by a gap layer of insulating material. Two of such workpieces (20, 20') are then placed with the edges in facing opposing aligned abutting relation and glass bonding is effected by means of the two bonding notches (26, 28).
