ABSTRACT OF THE DISCLOSURE In a magnetic memory storage device an enclosure is provided to contain the disk pack assembly and the recording head carrying arms, the enclosure being adapted for supplying filtered cooling air, thus eliminating heat generated in the operation of the equipment; and for reducing temp- erature gradients between the components within the enclosure. The spinning disks of the disk pack act as a centrifugal air pump and a shroud forming part of the enclosure is spirally shaped to increase the air flow through a sized air inlet thus reducing warmup time. This basic flow pattern is enhanced by the addition of two lesser air flow patterns, from above the pack and from below the pack around the drive spindle, so that an excess of cool incoming air does not contact the disks, thereby balancing top inlet air with bottom inlet air to control air movement.
