Abstract
A magnetic disk drive provided with a loadunload mechanism of the rampload type is disclosed, in which even if loading and unloading operations are frequently repeated, damage to a head due to impingement during the unloading operation is eliminated, and a ramp and the lift-tab of a suspension are less liable to wear, and an operation failure or malfunction due to wear debris is eliminated, thereby providing the drive of high reliability. The ramp is supported for minute displacement, and the posture of the ramp is changed during the unloading operation. The restraining members for restraining the posture of the ramp are provided, and the cushioning members are provided at portions that the ramp and the restraining members come into contact with each other. There can be achieved a drive of high reliability in which even if the loading and unloading operations are frequently repeated, damage to the head due to impingement of the lift-tab during the unloading operation is eliminated, and the lift-tab and the ramp are less liable to wear, and an operation failure due to wear debris is eliminated.
