A magnetic disk drive which can be inserted into and removed from a slot formed in an information processing apparatus. The magnetic disk drive includes a magnetic disk mounted on a spindle assembly, a magnetic head for writing and reading out data onto and from the magnetic disk, an arm having the magnetic head supported at an end thereof, a shaft for supporting the arm for pivotal motion, and an actuator operatively connected to the other end of the arm for pivoting the arm around the shaft. The magnetic disk drive further includes a lift member movable between a first position in which it is spaced away from the arm to permit the magnetic head to be contacted with the magnetic disk when the magnetic disk drive is inserted into the slot of the information processing apparatus and a second position in which it lifts the arm to bring the magnetic head out of contact with the magnetic disk when the magnetic disk drive is removed from the slot, a support for supporting the lift member for movement between the first and second positions thereon, and an interlocking device for moving the lift member between the first and second positions in response to insertion and removal of the magnetic disk drive into and from the slot of the information processing apparatus.
