Patent ID: 7275307

Claim:
A method for manufacturing a magnetic head having a pair of magnetic core halves fitted together in abutting relationship with a magnetic gap therebetween and having a slide contact plane for slide contact with a magnetic recording medium, said slide contact plane having a length extending in a general direction in which the magnetic gap extends and having end portions at opposite ends of said length of said slide contact plane, said method comprising steps of: forming said magnetic core halves; bonding said magnetic core halves together in an abutting relationship with the magnetic gap and track width regulating grooves provided at facing end faces of said magnetic core halves; forming in the slide contact plane, a groove at each end portion of the opposite ends of the slide contact plane; and forming a nonmagnetic portion by filling the grooves with a non-magnetic glass material so that the end portions at the opposite ends of the slide contact plane are comprised of the non-magnetic glass material.
