Abstract
Magnetic read heads with magneto-resistance effect of the multilayer type, are provided in a new arrangement making it possible in particular to facilitate a collective arrangement of these heads. Each read head comprises a magneto-resistance element formed by a sensitive magnetic layer superposed on a stable magnetic layer. Each read head comprises a magnetic circuit in a ring opened by an air gap, the sensitive magnetic layer being inserted in the magnetic circuit in a ring, the stable magnetic layer being outside the ring of the magnetic circuit. The arrangement of the magnetic read heads is particularly adapted for reading high density magnetic storage media.
