A technique for recording and retrieving small marks beyond the optical diffraction limit was proposed. The basic experiment with this technique was also carried out at a constant linear velocity of 2.0 m/s, rotating a disk with a multi-layered structure of Sb and GeSbTe, which were separated by a thin film of SiN. By use of the optically nonlinear property of the Sb thin film, carrier to noise ratio of more than 10 dB was obtained from recorded marks of 90 nm, using an optical system with the laser wavelength of 686 nm and a numerical aperture of 0.6.read more

Optical Phase Change Disc without Bulk Laser Initialization and a Quick Bulk Initialization Structure
TL;DR: In this paper, the recording and overwriting properties of optical phase change disc without bulk laser initialization were investigated. But the recording jitter of the 1-7 frequency modulation signal increased during the first 2 or 3 overwritings and then saturated at less than 3.5 ns until 30,000 overwritING iterations at a linear constant velocity of 12 m/s.
