Claims

[Scope of utility model registration request]

A groove substantially parallel to the tip of the main body and a concave introduction extending from the tip of the main body to a predetermined portion of the groove are formed on the outer surface of the cartridge body, which is a combination of upper and lower halves having an opening for insertion of a recording/playback head. A locking pawl, which is bent and formed at a predetermined portion of a shutter having a substantially U-shaped cross section consisting of a vertical surface and an upper and lower surface, is introduced and fitted into the groove from the concave introduction path on the outer surface of the main body, and the shutter is inserted into the groove. is slidably attached to the outer surface of the cartridge body, and a spring material stretched between the vertical part of the shutter and one side of the cartridge body allows the shutter to open the recording/reproducing head insertion opening. In an optical disk cartridge biased in the closing direction, the spring material is a leaf spring that is substantially perpendicular to the inner surfaces of the upper and lower halves, and the vertical width of the leaf spring is determined from the distance between the inner surfaces of the upper and lower halves of the cartridge body. An optical disk cartridge characterized by being slightly smaller.
