I recently recommended that a customer use an external hard drive as a backup device when they remarked, “You know, I don’t think I really know what a hard drive ...

In a volumetric optical disc medium, two counter-propagating light beams focusing to the same point create a diffraction-limited size micro-reflector. We propose a single-sided optical layout for a ...

Abstract: Nano recording and readout on optical disk are investigated by a novel characterization method with ultrahigh resolution. Optical and thermal mechanisms of nano recording and readout on ...
