ABSTRACT:
A magnetic disk drive having a rotary positioning mechanism which positions a magnetic head relative to a recording medium in a rotary motion. A suspension arm supports the head at the top thereof and is movable parallel with the surface of the medium in a rotary motion. As the suspension arm is moved toward the outer edge of the medium, it abuts against and urges the side of a lifter. As a result, the lifter is rotated about a pivot to lift the suspension arm with a lug extending out from the side thereof. The magnetic disk drive prevents the head from sticking to the medium, reduces the power consumption of motors, increases the resistivity to shocks and impacts during transport, and positions the head accurately at all times.
