Geometric testing machine for optical discs AudioDev

The ETA-GT II geometrical tester is a compact measurement system for all stages of disc manufacture - including stamper verification, half-disc and bonded discs.
It enables all relevant geometrical data to be determined, including the inner hole and the lead-in and lead-out diameter. The disc tray permits measurement of disc eccentricity relative to the inner groove (lead-in) as well as to the outer groove (leadout). With its easy-to-use, intuitive user interface, it provides a graphic representation of accuracy for measured geometrical data such as eccentricity, unroundness and layer shift of optical
discs or stampers.
While the ETA GT II serves CD as well as DVD, the ETAGT II / Blue provides one measurement system for all formats CD/DVD/BD.
