Pulsed UV Curing For Blue Laser Media

Next-generation media offer clear benefits over previous formats, but their production is more arduous. In particular, bonding and curing for Blu-ray Disc (BD) and HD DVD (HD) formats become more difficult. The processing method must provide low temperature curing with high surface uniformity. The curing technology must be capable of penetrating thick and multi-layer substrates, as well as curing a variety of substrate materials. Manufacturing high-definition discs is markedly more difficult than DVDs and CDs. The increase in content on each disc results in tightened manufacturing tolerances while market forces limit increases in cost. The moulding process becomes more critical, disc handling time decreases, and yet heat-related effects are less acceptable in these new formats. Pulsed UV solves a variety of problems facing BD and HD disc manufacturers, by offering a rapid curing technology for adhesive bonding and hard coat curing.
