海量存储蓝光技术

Memory Capacity for Blue-ray Technique

光盘以其体积小、容量大、可靠性高等特点,成为实现多媒体应用的一种重要的存储手段。从CD到DVD在存储的密度及读写速度已经有了长足的进步,但它们都采用红色激光波段进行数据的读取和刻写。随着信息对储存容量需求日益增长,蓝光技术应运而生,蓝光技术采用蓝色激光波段对数据进行读取和刻写,蓝光波长短,蓝光光盘存储容量大。

Compact Disc become an important memory way to carry out multimedia application based on the advantage of small bulk,big capacity and high reliability.Although the memory density and read-write speed have made long progress from CD to DVD,both of them adopt red laser wave band to read and write data.While the force of information needs more and more memory capacity,the blue ray technic emerges,and it adopts blue laser wave band to read and write date,which has short wavelength and big memory capacity.
