A technique is described for the measurement of transient temperatures, caused by occasional head-disk contact in a magnetic disk storage file, by the use of a thin film thermocouple. The thin film thermocouple is built on an air bearing slider 1 using thin film techniques. The thermocouple comprises conductors 2 of a first material X and conductors 3 of a second material Y. The two materials are deposited to form X/Y thermojunctions 4 at the air bearing surface (ABS) 5 of the slider 1. The thermocouple junction materials X and Y can be any two materials with different thermoelectric powers, such as the well known materials for thermocouple junctions, including nickel/iron, gold/platinum, or iron/constantan and any other appropriate material.
