The present invention enables a disc loading apparatus to handle both a bare disc and a disc housed in disc cartridge for writing/reading signals, which comprises a holding device consisting of a first holding device for elastically fitting with holding cuts provided at both sides of a disc cartridge inserted in an inserting gate and a second holding device for elastically holding the circumferential edge of a bare disc inserted in said inserting gate, which device is movable along a direction connecting said inserting gate and a table, and a transfer means to carry said holding device so that disc and a disc housed in said disc cartridge travel between said inserting gate and said turn table; thus a bare disc and a disc cartridge are selectively held by the holding device to be loaded.
