Erasable thermal phase change super resolution (EPSR) disks composed of mask and recording layers can be fabricated with a 揵elow-diffraction-limited?aperture within the readout spot to achieve optical...
A 揵elow-diffraction-limited?aperture within the readout spot for high-density recording can be achieved on erasable thermal phase change super resolution (EPSR) disks. Compared to the large aperture w...
Multilevel recording has an advantage of increasing the recording density without extensively altering altering the current optical configuration.Four-level recording schemes in phase-change disks usi...
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...
Comprehensive analyses based on the rigorous vector diffraction theory were used to simulate the polarized readout signals using a solid immersion lens (SIL) in reading phase change (PC) disks. For an...
This work investigated the enhancement of the data transfer rate and/or recrystallization speed of Ge–In–Sb–Te recording material by nitrogen doping. The effects of nitrogen content on the dynamic pro...
In this work, we studied the enhancement of overwriting characteristics of phase-change optical disks by doping in the dielectric layers. The doping elements included chromium (Cr), molybdenum (Mo), n...
We carried out a feasibility study on rewritable phase-change optical disks with more than two recording layers. Dynamic recording-playing evaluations of the test disks and Tx measurements revealed th...
