| Abstract: | Blue-laser optical recording is considered as the third generation of optical storage technology.The development of key technology of blue-laser optical storage is described.Two models named as Blu-Ray and HD-DVD were listed and compared.It is generally considered that HD-DVD is suitable for PC application;Blu-Ray is better for video disk recording.Some extended technologies of blue-laser optical recording such as multi-level,super-resolution near-field structure and multi-wavelength technologies are reviewed.The prospective development is discussed. |
