<p>A multi-channel current-perpendicular-to-plane (CPP) magnetoresistive read sensor 1 comprises a stack of layers 11-15 extending along a stacking direction z of the stack, and an edge surface S of the stack that is parallel to the stacking direction and further forms at least part of a bearing surface of the read sensor. The stack of layers comprises: a first contact layer 15, a free ferromagnetic layer 14, a non-magnetic layer 13, a spin injection ferromagnetic layer 12 and a second contact layer 11. The stack of layers further comprises a series of structures 30, each structure formed in both the first contact layer and the free layer. An edge surface of each of the structures is level with the edge surface of the stack and the series of structures extends along a direction x that is parallel to the bearing surface and perpendicular to the stacking direction. The structures may be defined by grooves 35.</p> |
