Process of manufacturing a side pinned magnetic recording sensor

A process is described for the fabrication of a magnetic read head in which contact between the pinned layer and the AFM is limited to their edges. The principal steps are to deposit an antiferromagnetic layer and to then pattern it into a pair of antiferromagnetic layers separated by no more than a...

Zusammenfassung:	A process is described for the fabrication of a magnetic read head in which contact between the pinned layer and the AFM is limited to their edges. The principal steps are to deposit an antiferromagnetic layer and to then pattern it into a pair of antiferromagnetic layers separated by no more than about 2 microns. A layer of magnetic material that lies between, and is in contact with, said antiferromagnetic layers is then deposited, following which the layer of magnetic material is magnetized.
