A flexible magnetic disc cassette carries a normally closed automatic slide shutter which selectively covers head access holes provided on the cover of the disc cassette. Basically, such disc cassette is designed for use with a disc drive mechanically which carries an automatic shutter opening system. In order to be able to use such cassette with a disc drive having no such automatic shutter opening system, the shutter is arranged to move on said cover to an extended position where the shutter is latched in an extended open position. Apparatus is provided which automatically operates the shutter of the cassette upon insertion of the cassette into the disc drive. |
