Abstract
Disclosed is a magnetic head comprising chiefly two thin or thick layers of magnetic materials located in a same plane and separated by a gap layer of non-magnetic material, also made in the form of a thin or thick layer. This gap layer forms a determined angle with the plane of the layers of magnetic materials. Methods are also provided for the making of such a head. In particular, these methods make it possible to determine, with precision, the angle of the gap with the plane of the layers of magnetic materials. Applications: magnetic write/read heads for computer peripherals (using tapes or disks), and possibly video tape recorders.
