Abstract
An apparatus according to one embodiment includes a magnetic sensor structure, a magnetic shield having at least one laminate pair comprising a magnetic layer and an electrically nonconductive nonmagnetic layer, and a nonmagnetic spacer layer between the sensor structure and the magnetic shield. In one embodiment, a deposition thickness of the nonconductive nonmagnetic layer in each laminate pair is about 10% or less of a total deposition thickness of the laminate pair. In another embodiment, a deposition thickness of the nonconductive nonmagnetic layer in each laminate pair is between about 1 and about 12 nanometers. In yet another embodiment, the magnetic shield has at least one second laminate pair, and a nonlaminated magnetic portion sandwiched between the at least one laminate pair and the at least one second laminate pair.
