  • Disc drive dynamic seal
    Patent number: 4429336
    Abstract: A rigid magnetic disc memory apparatus having an aperture formed in the base such that contaminants from the bearings are removed before they can migrate into the vicinity of the discs. In a preferred embodiment the aperture is located in the region of high pressure created by a rotor and stator assembly. The pressure differential causes air and contaminants to flow out of the disc drive enclosure. The pressure differential across the aperture is increased by connecting a duct between the aperture and the inlet side of the clean air supply blower.
