Automatic disc-feeding read-write printing device suitable for optically readable-writable disc and its method

The invention relates to an automatic dish supplying read-write printing device for an optical read-write dish and a method thereof. The device comprises a frame, a read-write and printing device and a dish supplying device. The read-write and printing device and the dish supplying device are arranged on the frame. The dish supplying device allows the dish to fall gradually on a tray of the read-write and printing device by gravity. The tray receives and closes movably to provide data copying and surface printing for the optical storage dish. The method includes the following steps: providingthe optical read-write dish, supporting the overlapped optical read-write dish by the dish supplying device, allowing the optical read-write dish to fall down gradually by gravity, holding the gradually fallen single optical read-write dish by the tray, closing the tray into the read-write and printing device and performing data copying and surface printing for the optical read-write dish on the tray by the read-write and
