Process for collective production of integrated magnetic heads with a supporting surface with a determined height. According to the invention the components of a board are thinned collectively be etching the board along area overlapping polar parts.

Method for collective production of magnetic heads having a bearing surface with specific height

A process for collectively making integrated magnetic heads with a bearing surface obtained by photolithography. According to the process, on a wafer is deposited a plurality of heads, a mask defining the profile of the bearing surfaces and the wafer is collectively engraved in the vicinity of the pole pieces of the heads. Such a process may find particular application to the making of magnetic heads.

Method for collective production of magnetic heads with rounded bearing surface

An assembly including a magnetic head for recording information using a chip based assembly. The assembly includes a chip mounted on a base where a printed circuit with conducting tracks underneath is passed through the base to come into contact with the chips's connection studs. Also disclosed is the process for the manufacture of chip based assemblies.
