Abstract

A recording cover (46) that provides a clean air distribution and micro cleanroom environment for recording of optical disc masters, while concomitantly serving the purpose of protecting the sensitive optically active lamina (31) during transportation and storage of the optical disc substrate. A rigid, opaque, and reusable recording cover concentrically and fixedly, yet removably, fits over the optically active lamina of a disc substrate and creates an enclosed contaminate free space (51) therebetween. The recording cover has a plurality of inwardly located air entrance cavities (54) and a plurality of circumferentially located air exit holes (52), whereby clean and dry air (53) is introduced into the air entrance cavities. The clean, dry air flows through the enclosed space and out of the exit holes under positive air pressure and centrifugal force during the recording phase. The air pressure flow, in conjunction with centrifugal force, removes both ablative and also spurious environment debris particles from the enclosed space, thereby preventing occlusion of recorded data pits on the optically active lamina by debris particles.
