Abstract

PURPOSE:To produce magnetic heads of vertical recording system by bonding first, second magnetic blocks of specific shapes via non-magnetic material then partially grinding away the first block and deposition a metal magnetic layer. CONSTITUTION:A second magnetic block 2 of U-form in section having serrated plane form protruding parts 12b1, 12b2 and a first magnetic block 11 of nearly flat plate form having serrated plane parts 11b1, 11b2 are bonded by way of a spacer 15 of non-magnetic material, after which the first magnetic block 11 is ground away down to the face shown by a dot-dash line (c) to expose the non-magnetic material having been deposited on the end face 12b1 of the second block 12. Next, a metal magnetic layer 18 of high saturated magnetic flux density such as permalloy or other is deposited on this surface 17, and further a non-magnetic material layer 19 such as of glass, ceramics or other to be a protecting layer is deposited on the outer side thereof, after which the layers is polished down to the face shown by a broken line (d). The assembly is then cut at the thickness shown by a broken line (e) to provide the magnetic head.
