Therefore, the authors have developed a new mastering process that can extend the resolution limit of the UV-LBR to realize the next generation DVD. It uses photobleachable dye (PBD) coated over a photoresist layer. In this paper, the effectiveness of the new multilayer mastering process is discussed, especially the writing ability ...

A simple manufacturing process of multilayer recording disks has been developed to fabricate a large-capacity optical disk of more than 40 GB, using a short-wavelength laser diode and high numerical aperture (NA) objective lens. Some existing production facilities for the digital versatile discs (DVD) are applicable to this process. These disks can be utilized for long-time video recording of high-definition TV broadcasting. ...

The variation of the milling parameters enables to control particle size, shape, functionality, specific surface area, and dispersability of the MG functional fillers. In this study, MG was used as functional nanofiller for the production of SiC/MG nanocomposites. The nanocomposites exhibit significantly improved tribological behavior. The results of rotating pin on disc sliding tests show that with SiC/MG a ...

In this study, a versatile model is developed to investigate the response of a variety of complex coatings. Through the investigation of three advanced surface coatings the developed model is shown to offer detailed subsurface stress and strain information, quantifying the benefits provided by the application of each coating. A number of rolling contact fatigue tests were also conducted to complement the computational simulations. An adapted twin disc testing machine was used to investigate the progressive ...
