Summary: | The method involves using a substrate (2) with one surface covered by a deposited magnetic layer (2'). A magnetic circuit (4) is formed with a conductor winding (9) which surrounds one of the magnetic head poles. The magnetic circuit includes two pole-pieces (5,7) separated by a non-magnetic spacer (6). The spacer spreads into the substrate layer. The structure is formed by successive etching of the substrate through a series of masks and deposition of thin films. The final assembly, including substrate, superstrate and active magnetic layer, is finally machined to define the vertical head surface. |
