In-Line Scanner for Rewritable Optical Media: CD-RW, DVD-RW, DVD+RW, DVD-RAM

Indispensable Solutions for All Rewritable Optical Discs

Reliable quality assurance and process control for CD-RW, DVD-RW and DVD-RAM requires the integration of up to four dedicated ISM in-line scanner systems into replication lines. After molding, the Substrate Scanner ISM.sub inspects for local defects within and on the surface of clear substrates. Half discs are inspected for local defects with the ISM.dvd after sputtering. The Bonded Disc Scanner ISM.dvd detects all local defects including bonding gaps after the bonding process. Finished discs are inspected by the Final Scanners.

The ISM.cd, ISM.dvd, and ISM.dvd-ram detect local defects at high speed and measure disc deformation and reflectivity with high precision. Additional features include Layer Stack measurement and Header Evaluation for DVD-RAM, providing indispensable solutions for rewritable discs. Leading DVD-RAM manufacturers from Japan and Taiwan have accomplished extensive benchmark tests and, without exception, selected the ISM.dvd-ram for integration into their production lines.
