Abstract
A magnetic disk drive having a disk for storing information, a spindle motor for rotating the disk, a head for recording information into the disk and reproducing information from said disk, a suspension supporting a slider provided with the head, a carriage supporting the suspension, a voice coil motor for exerting a rotational torque to the carriage so as to locate the head on the disk, a base and a cover, and a ramp serving as a guide for unloading the head from the disk. A part of the suspension slides over the ramp so as to effect the unloading operation and the position or the posture of the ramp is changed by sliding movement of the part of the suspension over and with respect to the ramp during the unloading operation.
