Abstract

After the manufacture of a recording disk is completed, the disk is washed by dipping it into a cleaning agent. The disk is then rotated until dry. With a center hub support, the cleaning agent collects under the hub. As the disk is spun, the cleaning agent slowly separates from under the hub and causes streaks on the dried surface. To reduce this streaking, the disk is supported on its edges by a clamping assembly as shown in the figures.

Disk Support for Spin Drying

After the manufacture of a recording disk is completed, the disk is washed by dipping it into a cleaning agent. The disk is then rotated until dry. With a center hub support, the cleaning agent collects under the hub. As the disk is spun, the cleaning agent slowly separates from under the hub and causes streaks on the dried surface. To reduce this streaking, the disk is supported on its edges by a clamping assembly as shown in the figures.

The clamping assembly includes a plurality of arms 1 each pivotably fastened to a support structure 2. The support structure 2 includes a shaft 3 which attaches to a drive means, not shown, for rotating the support structure 2. A rod 4 journaled within the shaft 3, pivots the arms via a ball and socket assembly 5. A handle 6 is fastened to the other end of the rod 4 for actuating the arms 1. A compression spring 7 can be used to force the rod 4 away from the disk, to pivot the arms 1 into holding contact with the disk.
