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.

HD DVD-R dual layer disc: High density DVD dual layer recordable disc for blue laser system (30GB/DVD-R size) can be produced in the current DVD-R dual layer mass-production line with low-to-high polarity organic dyes. Excellent recording characteristics have been confirmed with cost-effective normal stack dual layer structure.
