Method for the fabrication of a magnetic recording/reading head from a magnetic substrate |
摘要 |
A method for fabricating magnetic recording/reading heads. A substrate made of magnetic material is provided with a groove of a predetermined width. The surface of the substrate bearing the groove becomes the active face for the magnetic head. The face of the substrate having the groove is ground, and then filled with a non-magnetic material to form a gap. The filling causes the non-magnetic material to jut out of the groove. The material which juts out is ground off until the level of the substance is reached.
