Abstract

A reader portion (150) of a magnetoresistive head is disclosed. The reader portion (150) includes a magnetoresistive read element (156) for reading information from a magnetic media (216) and a non-magnetic element (153) to detect and cancel thermal changes in the read head. A spacer (155) is positioned between the magnetoresistive read element (156) and the non-magnetic element (153). A plurality of electrical contacts (166, 167, 168) connect the magnetoresistive read element (156) and the non-magnetic element (153) to external circuitry.
