A data storage device (40) for receiving a removable disk cartridge (10) comprises first and second members (70, 72) movably mounted in the data storage device. Each movable member is adapted to perform a respective function within the disk drive. A first spring (90) is coupled to the first movable member (70) for biasing the first movable member in a first direction, and a second spring (92) is coupled to the second movable member (72) for biasing the second movable member in the same direction. A single electro-mechanical device (74) has a drive shaft (76) that engages the first and second movable members at different positions during its travel from an extended position to a retracted position. By applying different currents to the electro-mechanical device (74), the first and second movable members can be operated independently. The data storage device therefore can achieve two functions using only a single electro-mechanical device.
