Abstract
Abstract An air filtrating disk drive slot dust protector comprises an air filtrating element attached to the front portion of a disk shaped supporting body, so that insertion of the protector into the disk drive causes the disk drive slot to be blocked by the air filtrating element, thereby keeping the dust from entering the disk drive slot but still allowing the cooling air to pass.
