There are many compelling arguments, worldwide, for the recording of indigenous art sites which are endangered by “people pressures”. The Baiame cave painting in the Hunter Valley of Australia (lat....
The possibility of achieving direct overwrite capability in magneti-optic thin films is demonstrated.By using films having a compensation temperature tens of degrees higher than the ambient temperatur...
The metallurgical states of rare earth-transition metal targets were found to be essential to produce high performance magneto-optical recording thin films.Our study indicates that in a vertical in-li...
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...
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 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...
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...
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...
The novel design and fabrication of a microlens on the front end of a single-mode fiber is described. The beam quality and spot size for optical recording applications are analyzed. A hyperbolic-shape...
Nitrogen and oxygen co-doped GeSbTe films for phase-change optical recording are investigated. It is found that optical properties of amorphous and crystalline state are similar to that of GeSbTe, cry...
An optical fiber-lens-type pickup with numerical aperture 餘A藜0:27 was demonstrated for thermal recording of continuous 1.6-mm-wide lines on MO disks with 50% throughput efficiency. Moreover, a Si-mic...
A volumetric optical disk that has multiple transparent films with optical switching layers is used as a recording medium to increase the number of recording layers. In the disk the optical switching ...
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...
This work investigates the thermal, optical and recrystallization properties as well as the microstructure of nitrogen-doped Ge–In–Sb–Te (GIST) phase-change material when irradiated by blue-light lase...
