Claims

[Scope of Claim for Utility Model Registration] (1) In an optical disk cartridge for storing an optical disk with recording surfaces formed on both sides, a frame member for regulating the movement range of the optical disk within the housing, and a frame member for controlling the movement range of the optical disk within the housing; an optical disk holding member provided with a protrusion that is pivotally supported on the outside and presses a side end of the optical disk; a tension spring member that urges the optical disk holding member against the optical disk; and a tension spring member provided on both sides of the casing. An optical disk cartridge characterized in that it is equipped with two accidental erasure prevention switches that display whether writing of data is permitted or prohibited on the recording surface of the optical disk corresponding to the surface concerned. (2) In the utility model registration claim described in paragraph 1, the accidental erasure prevention switch has a knob member formed on its display surface side, and the knob member is operated to move the switch to a data write permission position and a data write prohibition position. An optical disk cartridge characterized in that a window formed in a housing opposite to the display surface is closed or opened in accordance with the position of the optical disc cartridge.
