ABSTRACT:
In a pairing arrangement, a first half-disc and a second half-disc of an optical disc are bonded together by dispensing a bonding material onto the second half-disc and the first half-disc and second half-disc are placed in a chamber. The pressure within the chamber is reduced to a pressure below an ambient pressure and the first half-disc and the second half-disc are brought together within the chamber to distribute the bonding material between a surface of the second half-disc and a corresponding surface of the first half-disc and thereby form a paired disc. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
