Abstract
An apparatus comprises a slider configured for magnetic recording. The slider comprises an air bearing surface (ABS), a writer, a reader, and a plurality of electrical bond pads. A thermocouple is situated at the ABS proximate the reader and coupled to a pair of the electrical bond pads. The thermocouple is dimensioned to sense for a thermal asperity on a surface of a magnetic recording medium.
