ABSTRACT:
A magnetic disk memory has a disk pack with a revolving spindle, the disk pack being seated at both sides in a housing and being driven by a drive motor within the hub. The spindle is seated at mutually opposite walls of a supporting shell of the housing with a pair of ball bearings which are tensioned in the axial direction. To this end, each ball bearing is fixed with an interference fit on a respective axial peg of the spindle and is likewise disposed with interference fit in a respective bearing bushing. One of the bearing bushings is inserted into and fixed in a slot let into one wall of a supporting shell of the housing. Assigned to the other bearing bushing is a resilient wall section in the other wall of the supporting shell at which the second bearing bushing is fixed pressing inwardly against the spring power of this wall region.
