Abstract
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 () is drawn into a recording and reproducing position by means of a tray (), a shutter opening and closing mechanism () arranged on the side of the apparatus is relatively moved with regard to the cartridge (). Thereby, shutter plates () of the cartridge () are opened or closed. Then, after the shutter plates () are completely released, the shutter opening and closing mechanism () is retracted by means of a cam () to be away from the cartridge ().
