ABSTRACT:
A housing for a magnetic disk memory comprises a support shell and a cover for housing a magnetic disk pack and a rotational positioner. The disk pack is provided with two bearing locations one of which is secured to one lateral wall of the support shell and the other of which is defined by a slot open toward the edge of the supporting shell in an opposite lateral wall for receiving a disk pack bearing bushing. A seal is provided between the support shell and the cover for a dust-free seal of the interior of the housing, the seal being a closed sealing ring which is pinched at the parting plane between the support shell and the cover. The seal comprises a perpendicularly projecting semi-circular extension in the region of the slot--which encompasses the bearing bushing and is fixed to the exterior of the lateral wall in a recess formed therein.
