Paper Abstract

High density optical recording disk using vacuum evaporation deposited organic dye film is newly developed. As we investigate the signal characteristics of the vacuum evaporated disk in comparison with the disk fabricated by conventional spin-coat method, it is found that the vacuum evaporated disk has some features: to keep uniformity of tracking signal easily, high modulation, and wide power margin. Furthermore, it is clarified that the recording mechanism of the evaporated disk includes the hole formation by sublimation of the dye material. We confirm that the performance of the vacuum evaporated disk is high potentiality for DVD-R.
