High Speed HD DVD-R Disc with Organic Dye

摘要

High speed HD DVD-R disc with low-to-high polarity organic dye was developed. For development of organic dye, Type A and Type B having different properties in sensitivity and read stability were examined. 4x speed recording is possible with both Type A and Type B. Furthermore, in type B, the sufficient signal characteristics were obtained at 5x speed recording for single layer disc and 2x speed recording for dual layer disc.
