摘要： An arbitrary gap thin film magnetic recording head is fabricated by forming a substrate based on traditional vertical planar thin film head wafer technology which is designed to produce an integrated subgap and subpole substrate structure. The wafer is then processed into row bars to reveal, in a plane parallel to the transducing direction of the medium, the subgap and subpoles at the surface of the row bar and to bring the structure to a certain coil depth or gap depth. A flat or cylindrical contour may be utilized.This thin film subgap row bar is taken through a film deposition or growth process that deposits the magnetic film on a plane perpendicular to the wafer plane, horizontal planar processing, forming a surface film recording head where an arbitrary gap structure can be made in-between the subpoles and generally directly on top of the subgap. The surface thin film is deposited and patterned on the tape bearing surface of the head to optimize various element configurations, gap patterns and head-to-tape medium contact.An arbitrary gap thin film magnetic recording head is manufactured using two major thin film processing planes, one orthogonal to the other, the first major plane is wafer level and the second major plane is sub-wafer level and perpendicular to the first. The first major plane of processing defines the magnetically active substrate including coils, subgap and subpole members. The second major plane of processing defines the surface film which transmits the flux from the subpoles to the gap features contained in the surface film.This resulting structure is a recording head that is wired to the servo system electronics and will format the tape with the arbitrary gap pattern.

摘要： The present invention discloses a method of manufacturing a magnetic head in which a magnetic yoke is formed on a substrate in parallel thereto by the thin film process, which comprises the steps of forming a yoke-patterned recess in a non-magnetic material layer formed on the substrate; and forming a magnetic yoke layer in such recess while forming a non-magnetic gap portion approximately normal to the substrate; wherein a split portion is provided to the gap portion so as to recess behind a level where a slide-contact plane with recording media is formed, which results in a magnetic head which can successfully prevent the noise generation over a long period, and can improve the playback efficiency.

摘要： 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 sectioned second pole piece. The 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 the individual thin film layers of the transducer are deposited. A horizontal first pole piece is formed. A horizontal section of a second pole piece is formed and activated by a conductor coil wound around the horizontal section. The backgap is displaced horizontally from the poletips. The wafer is then divided into rows. The vertical section of the second pole piece is formed on the end of the row in contact with its horizontal section. The substrate is removed by attacking the release layers.

摘要： An arbitrary gap thin film magnetic recording head is fabricated by forming a substrate based on traditional vertical planar thin film head wafer technology which is designed to produce an integrated subgap and subpole substrate structure. The recording head includes a pair of magnetically permeable thin film subpoles, separated by a low permeability subgap structure. An electrically conductive coil may be embedded, in part, within the subgap structure. Thus, the subpoles and subgap structure form part of a magnetic circuit. A highly permeable magnetic surface film spans from one subpole to the other having one or more arbitrary gap patterns. That is, a surface thin film is deposited and patterned on the tape bearing surface of the head to optimize various element configurations, gap patterns and head-to-tape medium contact.

摘要： A method of formatting magnetic media includes providing an integrated thin film magnetic recording head having a recording element. The recording element includes first and second magnetically permeable thin film subpole members separated by a substantially low permeability subgap member. An integrated electrically conductive coil structure is embedded in part within the subgap member and in part in-between the first and second subpole members. The recording element also includes a magnetically permeable thin film layer spanning from at least the first subpole member to the second subpole member and including one or more arbitrary recording gap patterns. The direction of film growth of the magnetically permeable thin film layer is substantially orthogonal to the direction of thin film growth of the first and second magnetically permeable thin film subpole members. The method includes passing magnetic media over the magnetic recording head to format the magnetic media.
