Patent ID: 7694643

Claim:
A system for providing an optical disc, the system comprising: at least a molding machine producing substrates sequentially; a vacuum sputtering chamber; a cooling means to cool down the substrates to a desired temperature while the substrates are being transported to the vacuum sputtering chamber, wherein the substrates are sequentially sputtered with a type of reflective material; and a cover layer station including a first cover layer mechanism and a second cover layer mechanism and receiving the sputtered substrates, wherein the first cover layer mechanism is configured to provide one cover layer on a first side of each of the substrates and the second cover layer mechanism is configured to provide another cover layer on a second side of each of the substrates such that the optical disc presents a structure of a substrate sandwiched by two cover layers on both sides of the substrates, each of the first and second cover layer mechanisms includes: an upper part including a dispensing structure; a lower part including a disc positioning structure, wherein, when the upper part and the lower part are caused to move towards each other, the dispensing structure is released to engage the substrate placed on the disc positioning structure, a certain amount of a type of material in liquid form and at a predefined temperature is dispensed onto the dispensing structure, wherein the substrate is caused to rotate at a predefined speed so that the material is dispersed evenly onto a surface of the substrate by a centrifugal force; air pipes to inject to a certain amount of air onto the dispensing structure to blow off liquid residual on the dispensing structure; and a heater radiating infrared beams in different magnitudes to control temperature of the material so that the cover layer of uniform thickness is formed on top of the substrate.
