Abstract (en)
[origin: WO0054260A1] Magnetic head (1) having a head face (3) and a layer structure (7) comprising a first magnetic layer (13a, 13b), a second magnetic layer (17) and a thin insulation layer (19a, 19b) electrically separating these magnetic layers. At least the first layer of these magnetic layers comprises an amorphous cobalt alloy and is an integral part of the first magnetic layer comprising the amorphous cobalt alloy.
