A method and apparatus for vacuum assisted venting of an injection mold. The apparatus includes a main body structured to be mounted around an outer circumference of the injection mold and configured to facilitate application of a vacuum pressure therein. The method and apparatus are particularly directed towards preventing the accumulation of residual material inside an injection mold and reducing the frequency of disassembly and cleaning required for the injection mold.

A system and method are provided that allow an optical media inspection device to detect defects on or in optical media despite the presence of gross deformations in the media that would otherwise interfere with the inspection process. A holding device holds the optical media near the center while it is rotated for inspection. A negative displacement prohibitor impedes any negative displacement of the optical media. A positive displacement inhibitor, i. e. , air pressure exerted on the optical media, holds the optical media substantially flat while it is being inspected. A closed-loop feedback system may be used to control the amount of air pressure exerted against the optical media.

Automatic process control of the optical disc bonding process is achieved by tacking the adhesive and deforming the composite prior to final bonding. A separator chuck is used to maintain the separation of the disc halves through tack curing and a disc deforming jig is used during final bonding to compensate for any tendency of the disc halves to deform during the bonding operation.

An in-line system for fabricating a double sided compact discs by bonding together an information bearing surface and another surface, has a prestressing station with means for deforming at least one of the surfaces in such away as to not disturb any of the data. It employs an adjustable spacer for maintaining an adjustable separation between symmetrical arcuate portions of the outer circumference of the information bearing surfaces in the bonding station. This adjustable spacer comprises two spacer arms that comprise wedge shaped portions for entry between the edges of said discs and maintaining a displacement of at least the outermost edges of said discs. There is also disc displacement means for bringing together the two information bearing surfaces by displacement of at least one of said information bearing surfaces orthogonal to the plane of the surfaces.

Methods for bonding structurally asymmetrical or otherwise structurally dissimilar optical discs are provided. A bonded optical disc stack is formed from a first and a second optical disc by coating the back side of at least one of the optical discs with a light-curable bonding material and stacking the first and second optical discs back to back. The front side of the second optical disc is exposed to light for a first predetermined time period. The front sides of both the first and second optical discs are then exposed to light for a second predetermined time period. Finally, the front side of the first optical disc is exposed to light for a third predetermined time period. In this manner, when the second optical disc comprises program information and the first optical disc comprises a graphical image or other artwork, image pass-through due to simultaneous exposure and disc warpage due to one-sided exposure are significantly reduced.
