Agenda
  • CATS Blue laser project
  • Development overview
  • CATS B600 BDR Pro
  • Product presentation

3
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

4
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

5
CATS B600 BDR Pro
  • Product highlights
  • Reference drive
  • Fully digital environment
  • Designed to ensure an optimum measurement
    platform
  • Compact design with small footprint
  • Built-in power-supply and temperature-controlled
    fan
  • Designed for
  • BD-R
  • BD-RE
  • BD-ROM

6
System platform
  • New host architecture
  • CATS B600 BDR Pro
  • Stand alone unit (built-in power supply and fan
    unit)
  • PC with control software and measurement engine
  • Using the well-known CATS core functions (GUI
    etc)

TCP/IP

  • Built to be easy to service
  • Modular design

16
System platform
  • Display and control features
  • Control feature for the drive (start test,
    network setup etc)
  • Basic test result and status

Flip tray
New high-resolution display
Five-way navigation
17
Drive platform
  • The drive is specified by AudioDev and developed
    and manufactured by TOPTICA
  • No dependence on consumer drive components
  • All optical / mechanical / electronic
    specifications are kept 100 according to the
    standards
  • Reference class drive
  • Platform strategy the drive system is able to be
    adapted to several formats with reasonable effort
  • Blu-ray Disc and HD DVD possible

18
Drive platform
  • Single beam tracking
  • Supports Push Pull and DPD tracking
  • SA compensation possible
  • Tilt measurements possible
  • Supports DL
