We investigated the microstructure of phase change optical disks subjected to various initialization conditions using transmission electron microscopy (TEM). The effects of initialization powers on th...
Mask films for thermally induced superresolution readout in rewritable phase-change optical disks
Gerasable phase change mask films thermally induced superresolution readout cyclability tellurium
2011/11/29
Tellurium was studied as a mask film in a thermally induced superresoulution rewritable optical disk for detecting below-diffraction-limit marks.Mark trains of 0.15 could be retrieved with 9dB in carr...
Enhancing the Overwriting Characteristics of Phase-Change Optical Disks by Doping in Dielectric Layers
