Patent ID: 7918957

Claim:
A method of making composite optical discs continuously, the method comprising: forming a first, a second, a third and a fourth intermediate disc, each intermediate disc having a respective support layer and an information layer; transporting said intermediate discs to a sequencer; forming with said sequencer a first sequence of discs consisting of alternating first and third intermediate discs, and a second sequence of discs consisting of alternating second and fourth intermediate discs; feeding said first sequence to a first transfer station; positioning each first and third intermediate disc in pairs in a facing relationship at said first transfer station; separating the support layer from the information layer of the third intermediate disc, leaving the support layer of the first intermediate disc with the information layers of the first and third intermediate discs to form a fifth intermediate disc; feeding said second sequence to a second transfer station; positioning said second and fourth intermediate discs in pairs in a facing relationship at said second transfer station; separating the support layer from the information layer of the fourth intermediate disc, leaving the support layer of the second intermediate disc with the information layers of the second and fourth intermediate discs to form a sixth intermediate disc; and joining said fifth and sixth intermediate discs to form composite optical discs.
