  • Floppy-disk air and dust dam
    Patent number: 5530603
    Abstract: An apparatus for blocking air and dust from entering a floppy disk drive. A floppy disk has a compressible non-porous dam (a non-porous foam strip material) attached to the front-tip edge of the floppy disk. When the floppy disk is inserted into the drive the dam compresses to conform to the volume of the drive opening. Accordingly, air as well as dust is blocked from the disk drive and air flow is improved within the computer cabinetry.
