Abstract:
Both a new write-once medium with a sputtered NiO x film and a write-once optical disk using a blue laser has been fabricated. The optical constant of sputtered NiO x films for different ratios of O 2 /Ar was determined, and showed little dependence on sputtering ratios of O 2 /Ar and wavelength. The X-ray photoelectron spectra (XPS) data indicated those films have two major components, NiO and Ni 2 O 3 . Most NiO x films released oxygen gradually below 300°C. Over 300°C, there was an apparent transition due to the decomposition of the Ni 2 O 3 . At a writing power of 12 mW and a reading power of 0.5 mW under conditions of a numerical aperature (NA) of 0.65 and a wavelength of 405 nm, the carrier to noise ratio (CNR) was more than 47 dB and jitter was less than 13%. The recording principle depends primarily on the explosive pressure of the O 2 released due to laser heating of the NiO x film.
