Zusammenfassung: | PURPOSE:To reduce the cost of production and to obtain uniform recording and reproducing characteristics by increasing the number of the heads which can be produced on one sheet of substrate. CONSTITUTION:This magnetic head has a head element part 11 constituted of a thin film to execute recording and reproducing by coming into contact with a recording medium and a spring part 12 which is provided, partly superposing, on the rear surface of the contact surface in contact with the recording medium and impresses prescribed contact load to the head element part in the part extending from the head element part. This spring part 12 is formed as a film by sputtering on the rear surface of the head element part 11. Plural pieces of the head element parts 11 are formed on one wafer by a thin film forming method and thereafter, the respective head element parts 11 are parted and taken out discretely. The respective head element parts 11 are arranged apart spaced intervals of a proper length on the substrate by bringing their surfaces for contact with the recording medium into contact with the substrate. After a Cu layer is deposited over the entire surface, this layer is flattened flush with the surface of the head element parts 11 and further a material for the spring part is deposited over the entire surface. The substrate is thereafter parted to a prescribed head shape. |
