Abstract

Shown in the figure is an air barrier coating machine attachment 5 which allows the coating machine to coat to closer tolerance with less contamination. The device includes an ink spray gun 1 designed to permit closer proximity to the disk when the coating is applied, a stepper motor 2 direct drive gun slide assembly to accurately position the coating application, an air barrier slide 3 for sealing the air barrier surface, and an air barrier staging device 4 to maintain proper air barrier spacing during coating application and spin-off.
