Triangle-shaped movable shutter for data storage diskette cartridge

摘要

A cartridge for a disc-shaped recording medium, the cartridge including a cover shell and a base shell which house a flexible, magnetic recording medium therebetween. A movable shutter is provided along a front edge of the cartridge for covering, when in the closed position, an opening in each shell which allows a read/write head to access the recording medium. The shutter is windowless and has triangle-shaped portions which cover the read/write head access openings. The shutter includes a raised rib along its periphery and has a rounded corner. A raised rib may also be provided on the cartridge shell adjacent the read/write head access opening to prevent debris particles from entering the interior of the cartridge via the head access opening. The shutter is reinforced to prevent bending and has a rounded corner to minimize the chance that the shutter corner will become snagged on some other object, such as loose clothing.
