A method of making a multitrack head consisting in making a first network of grooves in a block of ferrite, filling the grooves with glass, planing down the surface, making a second network of grooves in a second block of ferrite, bonding these two blocks, trueing the base of the first block, depositing poles and making the winding wires go through.

The magnetic head has poles at each intersection of the matrix of wires. These poles connect the pads of the same column of pads, a gap being defined between the pads of the same intersection of wires and being parallel to the data wire.

A process of manufacturing an apparatus incorporating a layered thin film structure, wherein said process more particularly obviates the need to repeat on a first part of the apparatus the effects of certain operations required to produce the second part formed by the layered thin film structure. For this purpose, the process consists of utilizing a substrate to produce an intermediate assembly (12) comprising the thin film structure (11), then attaching the intermediate assembly (12) to the first part (10), then at least partially eliminating the intermediate substrate (13).
