The 3.5" Micro Floppy Disk (or MF2) additionally has a plastic shell that is somewhere between the 5.25" and 3" by way of stiffness. The dimensions is 90mm x 93mm. Just like the 3" there's a metallic shutter but it surely sits outdoors of the sleeve rather than within it, so it can be easily moved by hand mebel-stroy.ru to access the biscuit. Compact Floppy Disk (or CF-2) has a tough plastic shell surrounding the biscuit, https://pre-backend-vigo.ticsmart.eu/js/video/fjk/video-lass-casino-slots.html and https://profile.dev.agiledrop.com/css/video/fjk/video-slots-game.html the entry window is lined by a steel shutter that is moved out of the best way by sliding a mechanism accessed from the edge of the shell.
