Abstract

In many record storage disks of the digital signal storing type, it is desirable for several reasons to have a radially outward air flow between adjacent spaced-apart disk record members. In low-cost assemblies, rotation of the disks can induce such air flow--a self-ventilating pack.

Self Ventilating Storage Disk Apparatus

In many record storage disks of the digital signal storing type, it is desirable for several reasons to have a radially outward air flow between adjacent spaced- apart disk record members. In low-cost assemblies, rotation of the disks can induce such air flow--a self-ventilating pack.

The disk assembly is mounted on a suitable arbor and suitably clamped in the axial direction. A plurality of spacers in the form of washers is axially disposed between adjacent ones of the storage disks. Each disk has a plurality of apertures disposed in close proximity to the arbor, as best seen in the plan view. The apertures, in a preferred form of the apparatus, are partially covered by the spacers. Rotation of the assembly causes air flow to be induced through the apertures and then radially outwardly from the arbor.

In a more expensive version of the apparatus, and one which provides increased air flow, it is shown by the two apertures 10 and 11. In this version, the spacers have notches 10A and 11A circumferentially aligned with apertures 10 and 11 for maximizing air induction by rotation. Assembly of such an apparatus requires that each spacer be precisely aligned with the disk apertures. This alignment is conveniently provided by a keyway in the arbor, as at 13. The spacers, disks, and clamps can have corresponding keys, which fit keyway 13 for precisely circumferentially aligning the spacer notches 10A and 11A with apertures 10 and 1...
