China Record Corporation and China Film audiovisual Publishing House produced the CBHD high-definition programming disc. The CBHD can maximize to employ the existing CD industrial base in China. The international DVD Forum has approved the related patents and the full specification, as well as admitted the CBHD format standards. 1 The Advanced Efforts for Multi-dimension Optical Storage 3-Dimension (3D) Optical Storage 3D optical data storage can give to any form of optical data storage in which information recorded and read with three dimensional resolution.
The effective numerical aperture (NAeff) of the whole system can be expressed as NAeff = nsÁsin hm, where ns is the refractive index of the SIL. But a solid immersion lens (SIL) has higher magnification and higher numerical aperture than common lenses by filling the object space with a high-refractive-index solid material. There are two types of SIL: Hemispherical SIL–Theoretically capable of increasing the numerical aperture of an optical system by n, the index of refraction of the material of the lens.
5 as file system. BDXL discs are not compatible with existing BD drives though a firmware update may be available for some newer drives. “Blu-ray Disc recordable” refers to two optical disc formats that can be recorded with an optical disc recorder. BD-Rs can be written to once, whereas BD-REs can be erased and re-recorded multiple times. The current practical maximum speed for Blu-ray Discs is about 12Â. Higher speeds of rotation (10,000 + rpm) cause too much wobble for the discs to be written properly, as with the 20Â and 52Â maximum speeds, respectively, of standard DVDs and CDs.
