Apparatus and method for forming reflective layer of optical disc

Improved techniques for forming a reflective layer of an optical disc are provided. One improvement includes forming the reflective layer over an information layer of the disc by utilizing a metallizer and a masking device having an angled lip configured to align to an outer edge of the information layer. The masking device allows the applied reflective layer to extend to the outer diameter edge of the information layer, and shields plasma generated by the metallizer from reaching internal components of the metallizer. The masking device may include a pusher having a spring mechanism attached to an inner masking portion of the masking device. When the disc and the pusher are brought into relative contact with each other by application of a first force to at least one of the masking device and the disc towards the other, the pusher is spring-loaded and is pushed up into a recess of the inner masking portion, and when the first force is removed, the spring-loaded force of the pusher pushes the disc away from the masking device.
