Abstract

A read/write head for use in recording and reading data on perpendicular recording media comprising a first elongate magnetic member and a second U-shaped member having a base member and two leg members, said base member being parallel to said elongate member and said leg members being supported by and integral with said base member and extending toward said elongate member, one of said leg members being longer than the other shorter of said leg members, whereby said first elongate magnetic member and said second U-shaped member are secured together with an open gap portion defined between the other shorter leg of said second U-shaped member and said first elongate magnetic member, said gap portion being adapted to be proximate to said recording medium during use of said read/write head, said first elongate member comprising a magnetic member having an elongate layer of magnetic material carried on and extending longitudinally along a face of said first elongate magnetic member and terminating proximate said recording medium in a pole tip end having a width and thickness operable to establish the resolution of the head when said head is used for accessing said information, said first elongate magnetic member terminating in a region having a narrowed end slanted in part toward said pole tip, whereby when driven by a write current, said narrowed end of said first elongate magnetic member will saturate magnetically leaving said pole tip end as the only effective recording surface of said head.
