Abstract
In a magnetic disk memory comprising a disk pack hub seated at both sides in ball bearings in a housing, the ball bearings are tensed in the actual direction relative to one another in order to achieve a play-free hub guidance. To this end, at least one housing wall is resiliently designed in the direction of the hub axis and flexes upon the application of a restraining force. Before integration into a completed memory unit, the spacings of the inner rings of the ball bearings, tightly seated on the hub shaft, and of the bearing locations in the housing which accept the outer rings with an interference fit, deviate slightly from one another.
