ABSTRACT:
An improved glide head is useful for testing the glide quality of a disc. The glide head includes an air bearing surface, pads extending from the air bearing surface and a contact sensor, the contact sensor providing an output in response to an impact on the pad. The air-bearing surface defines a resting plane. The pad protrudes from the air-bearing surface such that the pad projects below the resting plane of the air-bearing surface.
