Abstract
The surfaces of a recorded disc are coated with a thin layer of lubricant by forming in an atomizer chamber droplets of the lubricant supported in air. The droplets are formed by passing a flow of air through a supply of the lubricant in the atomizer chamber at a rate and pressure such that the air causes the lubricant to be blown into the space above the supply as fine droplets. The air laden with the lubricant droplets flows out of the atomizer housing to a pair of nozzles in a coating chamber. The nozzles direct the air laden with the lubricant droplets onto the surface of the recorded disc which passes between the nozzles. Excess lubricant which does not coat the disc is collected in the coating chamber and carried back to the atomizer housing.
