Claims

[Scope of utility model registration request]

A magneto-optical disk storage case consisting of an upper and lower half having a pair of upper and lower writing windows and a reading window is provided with a slider that slides along the one end, and the slider opens and closes the writing window and the reading window. In the shutter mounting structure of a rewritable magneto-optical disk cartridge, which is equipped with a shutter having an approximately U-shaped cross section, the corner between the vertical surface of the slider facing the vertical surface of the shutter and the top surface of the slider, and the slider. A notch with a substantially triangular cross section is provided at a predetermined position at the corner between the vertical surface of the shutter and the lower surface of the slider, and a recess continuing to the notch is provided on the upper and lower surfaces of the slider on the back side of the notch. A shutter mounting structure for a rewritable magneto-optical disk cartridge, characterized in that a cut-and-raise pawl formed on the lower surface crosses over the notch of the slider and engages with a recess of the slider.
