蓝光技术被认为是第三代光存储的主流技术。介绍了蓝光存储中关键技术的发展过程,并对Blu_Ray和HD_DVD两种蓝光光盘的主流技术方案进行了比较分析。通过分析和比较后认为:HD_DVD技术方案具有较好的兼容性,因而较适合在PC机中应用;Blu_Ray技术方案具有容量大的优势,因而较适用于作为视频传播媒体。对蓝光存储的一些扩展技术,如蓝光多阶技术、蓝光超分辨近场结构技术和蓝光多波长技术等进行了综述。展望了蓝光技术的发展前景。
Blu-ray technology is considered the third-generation optical storage mainstream technology. The development of the key technologies in Blu-ray storage is introduced, and the mainstream technologies of Blu-Ray and HD-DVD are analyzed. After analyzing and comparing, it is considered that the HD_DVD technology solution has better compatibility and thus is more suitable for application in a PC. The Blu_Ray technology solution has the advantages of large capacity and is therefore suitable for use as a video media. Some extended technologies for Blu-ray storage, such as Blu-ray multi-stage technology, Blu-ray super-resolution near field structure technology and Blu-ray multi-wavelength technology are reviewed. Looking forward to the development of blue-ray technology.
