Abstract
A disc cartridge has an optical disc (13), first and second halves (15), (16) and a slide shutter (14), in which the slide shutter (14) is removably supported between the first and second halves (15) and (16), whereby it is possible to prevent erroneous opening and closing operations by making it difficult for a user's hand to touch as well as to prevent a loss of an information record by such an arrangement which is difficult for minute trash and dust to intrude.
