Abstract
Abstract A housing for a magnetic disk memory is assembled of a lower part and cup-shaped upper part which is seated on the rim of the lower part. A continuous angular bracket is secured to the inner surface of the lower arm and overlaps vertically the rim of the latter. An elastic sleeve has a mounting groove engaging the inwardly projecting arm of the bracket, and another mounting groove engaging a plate for supporting a rotary drive for the disks and a magnetic head assembly. The elastic sleeve further includes a flexible lip which abuts against a continuous shoulder on the inner surface of the upper housing part to seal the interior of the housing against outer atmosphere.
