摘要
We realized an inorganic write-once disk using a high numerical aperture (NA) objective lens and a blue-violet laser diode. Its recording layer was Bi-Ge nitride alloy which was more environmentally friendly than that of the rewritable disk. The data-to-clock jitter of 5.7% was obtained at 25 GB capacity, using the limit equalizer. In addition, we confirmed that this disk had potential for application as a 1X-2X recordable disk.
