摘要： A front loading apparatus adapted for use in a disc drive unit comprises an outer holder movable to approach or to depart from a central spindle and an inner holder contained in the outer holder and allowed to move toward up and down in the outer holder by a gap formed between the holders, so that a disc cartridge is accurately set by a setting device at a location for storing and reproducing signals in the apparatus. The setting device comprises push pin for pressing the center hub of the disc cartridge toward the central spindle at the stage when the outer holder approaches to the nearest with respect to the central spindle and for releasing the pressing force from the center hub when the outer holder departs substantially from the central spindle.
