CATS Blue laser project

• The future is now!
• Blu-ray discs and writers are already on the
  market
• Disc and drive manufacturers need tools for their
  media and drive development
• AudioDev choose Toptica Photonics as drive
  supplier
• Control of drive development
• Implementation of necessary functions
• Close cooperation with Philips ODTC

CATS Blue laser project

• AudioDev Blu-ray Disc Laboratory Set-up has been
  available since Q104
• AudioDev was the first non Japanese contributor
  company to join the Blu-ray Disc Association, BDA
• AudioDev is taking an active role in the BDA
• The drive and CATS analyzer has been successfully
  been used in RRT within BDA
