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...
Optical disk mastering using optical super resolution technique
disk mastering thermal-induced superresolution lithography
2011/11/29
A new laster lithography technique using the effect of optical superresolution can effectively reduce the exposed spot size on a photoresist layer,thus allowing disk mastering toward higher density us...
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 ...
Enhancement of Data Transfer Rate of Phase Change Optical Disk by Doping Nitrogen in Ge–In–Sb–Te Recording Layer
Ge–In–Sb–Te recording material data transfer rate recrystallization speed nitrogen doping
2011/11/25
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...
Super-Resolution Recording on an Optical Disk with a Platinum Oxide Layer
Optical disk Super-resolution Platinum oxide
2009/6/8
Bit-by-bit detection is achieved at a recording density of 0.11 μm pits on a super-RENS disk with a platinum oxide layer. Pits and spaces are arranged as a recording pattern for pit position recording...
