Abstract: A cross flow system for metalizing compact discs, capable of being interposed in-line in the production of the compact discs after premastering, mastering, electro-forming, and molding includes a vacuum chamber having diametrically opposed vacuum locks and multiple metalization sources in the form of magnetrons, with a preferred cross flow including the introduction of a disc to be metalized through one lock and the exit of the metalized disc through the diametrically opposite lock. The double vacuum lock diametrically opposed cross flow system eliminates the problems of throughput limitations, high rate deposition, substrate pitting, and software complexity due to indexing which makes prior systems both costly and inefficient. The system also permits processing of more than one substrate or compact disc title such that multiple titled compact discs can be processed simultaneously.

Abstract: An apparatus for the spin coating of substrates including a substrate carrier, a motor for rotating the substrate carrier, and a spinning bowl surrounding the substrate carrier. A lid is also provided in this spin coating apparatus which at least partially covers the spinning bowl for diminishing the escape for fumes into the ambient atmosphere during the spin coating of a substrate carried by the substrate carrier. The lid is also designed for improving the air flow around the substrate carried by the substrate carrier during the spin coating of the substrate.

Abstract: A system and method for tracking compact discs during manufacture comprising a spindle having a central shaft and a base for carrying a plurality of compact discs, electronic memory storage system connected to the spindle, and data transfer means cooperating with the spindle to send and receive information identifying compact discs carried by the spindle and/or providing processing information about compact discs carried by the spindle from or to the electronic memory storage system.
