<p>A flying head slider (10') is flown above a rigid rotating magnetic disk (37) at such a height that it is both aerodynamically stable and immune to collisions with disk asperities (36). A position adjustable magnetic transducer (2') is mounted on the slider (10') 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 (25') detects the presence of asperities (36) on the disk in the path traversed by the transducer (2'), and generates a control signal which causes the transducer to be retracted to a safe height.</p> |
