Method and apparatus for producing a multilayer storage media

摘要

A method and device for manufacturing a disc-shaped workpiece comprises the steps of producing a first and second disc-shaped substrate, applying an adhesive on at least one of the flat sides of said first and second substrates, bonding said substrates to form said disc-shaped workpiece and removing an excess of adhesive at the outer rim of the disc shaped workpiece by means of a liquid while rotating the workpiece on a rotating table. The liquid is being dispensed by a supply system comprising one or severeal nozzles, used liquid is collected by a suction device.
