ABSTRACT:
An integrated structure is provided for magnetic recording which utilizes a silicon wafer having two parallel faces which are crystal planes of orientation 100. One face is designed so as to constitute a displacement plane when used as a read and write device in a magnetic support. The magnetic head has a horizontal structure and is integrated into the silicon wafer in the face having the displacement plane. An electronic circuit is integrated in the silicon wafer in one of the two faces and connections are provided between the magnetic head and the electronic circuit.
