Abstract

Radial tilt adjustment method with Partial Response Signal-to-Noise Ratio (PRSNR) was newly developed. This method is able to adjust radial tilt rapidly, because the method uses the detected signal with polarity to radial tilt. Furthermore, the method has the accuracy of adjustment within ±0.1 degree, which is enough for HD DVD.
