Abstract
A head suspension for maintaining a gap between a read-write head and a data storage disk comprises a heater for heating gas in the gap; and a sensor for generating an output indicative of the thickness of the gap. The sensor generates the output in dependence on thermal conductance across the gap. The apparatus can be used to control the thickness of the gap.
