Two improved methods of achieving direct overwrite without a pulsed magnetic field to write or erase dingle-layer magneto-optical media with a compensation point of 125-130 and a Curie temperature of ...
The possibility of achieving direct overwrite in magneto-optic thin films is demonstrated. By using films having a compensation temperature tens of degrees higher than room temperature, writing and er...
Control of parameters in rare earth- transition metal alloys for magneto-optical recording media
2011/12/1
The techniques which can be used to control the magnetic and occurs when the temperature in the heated spot increasesufficiently magneto-optical recording properties of sputtered amorphous thin films ...
The dynamics of domain formation in a GdTbFeCo film during a full cycle of thermomagnetic (TM) recording has been studied by a time-resolved polarized-light
microscope. The microscope has 5 ns tempor...
The magnetoresistance effect in compositionally modulated transition metal/transition-metal films (Co/Pt and Co/Pd) and in amorphous binary rare-earth-transition-metal alloy films (TbFe) has been inve...
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...
A dual-layer optical disk comprised of a read-only layer and a phase-change layer was designed to perform the read-only and erasable dual-functionality in an optical disk. With the properly designed d...
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...
