Abstract

A housing for a magnetic disk memory comprising a disk pack rotatably seated at both sides and a rotational positioner is subdivided along a parting plane parallel to the axes of the disk pack and the rotational positioner, being subdivided into a tub-shaped supporting shell and into a cover. Both bearing locations for the disk pack lie just within the edge of the supporting shell and the immersion depth of the rotational positioner into the supporting shell is as small as possible. As a base, the supporting shell comprises an end wall inclined at a predetermined angle relative to the parting plane, the inside of the end wall, however, comprising an attachment surface aligned parallel with the parting plane in the attachment region of the rotational positioner. Outwardly directed webs are provided on the outer surface of the end wall and extend at right angles with respect to one another for the purpose of reinforcement.
