摘要:
A robust recording head with a spin tunneling sensing element separated from an interface between the recording head and a recording media so as not to be affected by collisions and other ill effects at the interface between the recording head and the recording media. The spin tunneling sensing element includes a pair of magnetic elements wherein one of the magnetic elements functions as a flux guide that conducts magnetic flux emanating from the recording media away from the interface to an active area of the spin tunneling sensing element.
