High Quality Film Nanoimprint Technology for Blu-Ray Disc (BD) Media

Thermal nanoimprint of roll to roll technology for DVD (t=0.6 mm) media realized fast 8 discs/s process and a new platen film nanoimprint process with stamper cooling method resolved the film shrinkage issue. The speed is as fast as 1 s and the film thickness is 75 mum. Dual layer Blu-Ray based disk of injection mold (t=1.1 mm) L0 layer and nanoimprinted (t=75 mum) L1 layer shows signal jitter around 6.0% high quality characteristics
