    Abstract: A DISC CATRIDGE (110) INCLUDES A CARTRIDGE BODY (111) HAVING AN OPTICAL DISC (112) ROTATABLY ACCOMMODATED IN THE CARTRIDGE BODY (111) AND HAVING AN APERTURE (114) RADIALLY TO EXPOSE A PART OF A SIGNAL RECORDING REGION OF THE OPTICAL DISC (112) TO OUTSIDE, A SHUTTER (115) MOVABLY MOUNTED ON THE CARTRIDGE BODY (111) TO OPEN OR CLOSE THE APERTURE (114) OF THE CARTRIDGE BODY (111), AND FIRST AND SECOND DISCRIMINATING SECTIONS (101, 102) PROVIDED ON OUTER SIDES OF THE CARTRIDGE BODY (111) TO INDICATE THE TYPE OF THE OPTICAL DISC (112) ACCOMMODATED WITHIN THE CARTRIDGE BODY (111). THE DISC CARTRIDGE (110) HAS THE FIRST AND SECOND DISCRIMINATING SECTIONS (101, 102) SET TO OPEN OR CLOSED STATES AND THE TYPE OF THE DISC (112) HOUSED IN THE CARTRIDGE BODY (111) IS DISCRIMINATING ON THE BASIS OF THE COMBINATIONS OF THE STATES OF THE FIRST AND SECOND DISCRIMINATING SECTIONS (101, 102). A DISC RECORDING AND/OR REPRODUCING APPARATUS, IN WHICH THE DISK CARTRIDGE (110) INCLUDING THESE FIRST AND SECOND DISCRIMINATING SECTIONS (101, 102) IS LOADED, INCLUDES A DETECTING UNIT TO DETECT ONE OF THE DISCRIMINATING SECTIONS (101, 102) INDICATING REFLECTANCE OF THE OPTICAL DISC (112) AND SETS AN OUTPUT LEVEL OF A LASER LIGHT IRRADIATED ON THE OPTICAL DISC (112) BASED ON AN OUTPUT OF THE DETECTING UNIT.(FIG 18)
