The Theroetival Study Of Improving Performance Parameter Of Optical Storage

One of the great problemms of the Information Age is how to store the glut of sound,images data and words that assult our senses everday.As the world becomes more interconnected and complex,it is very important to master the technology of storage,dispose and transmit of optical information.The optical disk storage technology emerged in the seventies of the 20^th century.Because its information is carried by light wave,it has hight storge density,hight input speed,low cost and durable.It has become one of key techonologies of multimedia and information high way.In this paper,the basic principles of optical storge technology and the basic structure of drivers were introduced,the factor that affect the performance parmeters were analyzed,through theoretical calculation,the improving optical storage capacity and density,the data rate and access time method is represented,in which introduced with emphasis the improving storage capacity and the density method. In the traditional by shorting the laser wave ,mcreases the numerical aperture in the foundation,proposed the breakthrough diffraction linit method.Reduction facula size by three-dimension optical storage and use SIL achieve near-field optical storage.
