Abstract
A flying head slider is flown above a rigid rotating magnetic disk at such a height that it is both aerodynamically stable and immune to collisions with disk asperities. A position adjustable magnetic transducer is mounted on the slider and is controllably lowered to an operating position very close to the disk where its position is maintained by a servo system. An anticipator probe detects the presence of asperities on the disk in the path traversed by the transducer, and generates a control signal which causes the transducer to be retracted to a safe height.
