摘要：A disc type recording and/or reproducing apparatus automatically performs the opening and closing of a shutter provided on a cartridge housing an optical disc in its case, and prevents the above-mentioned opening and closing mechanism from affecting the cartridge after an end of loading. When a DVR cartridge ( 51 ) is drawn into a recording and reproducing position by means of a tray ( 13 ), a shutter opening and closing mechanism ( 65 ) arranged on the side of the apparatus is relatively moved with regard to the cartridge ( 51 ). Thereby, shutter plates ( 100 ) of the cartridge ( 51 ) are opened or closed. Then, after the shutter plates ( 100 ) are completely released, the shutter opening and closing mechanism ( 65 ) is retracted by means of a cam ( 85 ) to be away from the cartridge ( 51 ).
