FABRICATION OF SIDE-BY-SIDE FOR MIMO RECORDING

摘要

The embodiments of the present invention relate to a method for forming a magnetic read head having side by side sensors. The method includes depositing a pinned layer, a barrier layer and a free layer over a shield, and removing portions of the pinned layer, barrier layer and free layer to expose portions of the shield. A bias material is deposited over the exposed shield. An opening is formed in the free layer to expose the barrier layer, and an insulative material is deposited into the opening. The resulting side by side sensors each has its own free layer separated by the insulative nonmagnetic material. The side by side sensors share the pinned layer.
