Erasable Phase Change Disks with Super Resolution Capability by Pulse-Readout
erasable thermal phase change super resolution disk (EPSR) optical super resolution mask layer recording layer below-diffraction-limited aperture pulse-readout
2011/11/30
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...
Volumetric optical disks comprising multiple data layers have been proposed to multiply recording density. Owing to the presence of out-of-focus data layers, interlayer cross talk is induced in readou...
Effects of ApertureWall on the Readout Signal of Erasable Thermal Phase Change Super Resolution (EPSR) Disks
