The present invention provides a floppy disk drive which can removably receive a cartridge containing a floppy disk and which can travel a READ/WRITE head to the desired track on the floppy disk while rotating the floppy disk at a constant speed for effecting the desired read/write action under an electric-magnetic conversion. The drive is of a top-up type which includes a frame portion and a carrier which can be popped up from the frame portion. The frame portion includes a spindle motor for directly driving the floppy disk, a plurality of positioning pins for positioning the disk cartridge relative to the spindle motor, and a carriage carrying the READ/WRITE head for travelling the head to the desired track on the disk. The carrier is pivotably supported by the frame portion and adapted to receive the disk cartridge. The cartridge can be loaded into the lower portion of the carrier upon popping-up of the carrier. When the carrier is engaged by the frame, the cartridge is upwardly moved to a predetermined position within the carrier.
