ABSTRACT:
A visual disk-capacity indicator for indicating to a user an approximate amount of disk space available for recording data on a floppy disk is located proximate a peripheral edge of a cartridge housing the floppy disk. The visual disk-capacity indicator includes a transparent window that provides visual access to an indicator needle. The window includes indicia showing various capacity levels ranging from empty to full. The indicator needle has a first end slidably engaged with a first guide rail and a second end slidably engaged with a second guide rail to maintain a longitudinal axis of the indicator needle in a parallel relation with the indicia. An access opening at the peripheral edge of the cartridge proximate the visual disk-capacity indicator allows a small external arm to enter the cartridge to adjust the indicator needle. The indicator needle may also be adjusted by magnetic member.
