Tunable feedback transducer for transient friction measurement |
摘要 |
A system for measuring transient friction of a head-disk interface in a magnetic disk storage device employs a servo system for accurate measurements. A first movable member carries a slider simulating a magnetic head which rests on a disk when said disk is at rest. The movable member is movably mounted to a second fixed member. A frictionless detector detects a displacement of the movable member relative to a position of the fixed member produced by a force due to friction when the disk spins. A servo system maintains a fixed distance between first and second members in response to an output from the detector and moves the movable member in response thereto. The output is taken from the servo system and provides a signal proportional a force due to friction exerted on said movable member.
