Abstract
A read/write head with a bottom shield on a slider substrate and a shared shield spaced apart from the bottom shield. A write head is deposited on the shared shield. A read sensor is spaced apart by reader magnetic gaps from the bottom shield and the shared shield. Electrically insulating layers in the reader magnetic gaps form a thermal resistance between the read sensor and the shields. A thermally conducting nonmagnetic layer in a reader magnetic gap reduces the thermal resistance without a corresponding reduction in the reader magnetic gaps.
