Record Disk Assemblies

In some record disk assemblies having a plurality of spaced-apart disks, it is desirable for several reasons to have circumferentially uniform, radially outward, air flow between the disks.

Such air flow can be provided by employing a fluted arbor for the disk pack assembly. Each of the record disks in the preferred form has radially extending slots 13, which match with flutes in the arbor to provide interdisk fluid communication. Such slots extend beyond a solid spacer or washer 12, as shown on the left side of the two figures.

In the alternative, as shown on the right side of the figures, spacers 12 can be slotted at 14 with apertures 15 being in the record disks. With the illustrated arrangement, all the spaces between adjacent disks are in fluid communication with the fluted arbor fluid passageways, yielding a circumferentially uniform radial air flow.
