Abstract: To reduce the size of a filming apparatus for recording information on an optical disc type recording medium, it is constructed such that: supporting portions for mounting a grip belt are provided on two structural members (not a cartridge cover) constituting a main body, respectively arranged on both sides of the filming apparatus; the optical disc is inserted or removed vertically with respect to a filming direction; a round-shaped cartridge is used as a cartridge whose dimension is: 5.2 mm in thickness, 80 mm in length (or width) of the disc plane, and 80 mm+5 mm in width (or length) of the disc plane; the angle between the opened cartridge cover and the filming apparatus to the line along an axis of supporting points of the cartridge cover is within the range from 23° to 34°; and a motor is used to open the cartridge cover.
