  • Patent number: 5742998
    Abstract: A plurality of suspension and magnetic head combinations are made on a wafer for longitudinal recording. A horizontal first pole piece and horizontal and vertical components of a second pole piece are formed with a magnetic gap between the first pole piece and the vertical component of the second pole piece. The suspension layers are formed mainly from the insulation layer that separates the horizontal first pole piece and the horizontal component of the second pole piece and an insulation layer that covers and protects the pole pieces. The layers of the combination head are deposited on a wafer in rows and columns. A release layer is deposited on the wafer and then the individual thin film layers of the magnetic head are deposited. The wafer is then divided into rows. The vertical component of the second pole piece is formed on the end of the row in contact with its horizontal component.

  • Patent number: 5655286
    Abstract: A method of making a combination suspension and transducer magnetic head for longitudinal recording which can be used for contact recording and flying above the media. The transducer includes a horizontal first pole piece and a horizontal and vertical sections of a second pole piece. A magnetic gap is formed between the first pole piece and the vertical section of the second pole piece. The suspension layers are formed mainly from the insulation layer that separate the first horizontal pole piece and the horizontal section of the second pole piece, and an insulation layer that covers and protects the transducer layers. The layers of the combination head are deposited on a wafer in a row and column configuration. A release layer is deposited on the substrate, first and then individual thin film layers of the transducer are deposited to form the horizontal first pole piece and horizontal section of the second pole piece which is activated by a conductor coil wound around the horizontal section.
