Along with the maturation day by day of industries such as computing machine, communication, consumer electronics, for the also increase day by day of demand of recording medium, to reach a large amount of purposes that circulate of information with high storage capacity, small size and low manufacturing cost.Yet the storage volume of traditional magnetic recording medium is applied required, and optical record medium since have high capacity, processing procedure easily, read fast and be easy to advantage such as preservation, become the main flow of present storage audio and video information to replace magnetic record medium gradually.
In optical record medium, numerical data utilize usually the position thickness, refractive index and absorption coefficient difference and be written into and identification.Since can be parallel write or read information, so optical record medium is also convenient many than magnetic record medium in the use.In practical application, optical record medium often is formed the form of CD, similarly is CD-ROM (can only read) or CD-WORM (can write once to reach repeatedly and read), conveniently to use and to operate.Yet, in existing optical record medium with 2-D data figure, because diffraction of light limitation (light diffraction limit) makes its maximum storage capacity that can reach that certain restriction also be arranged.Though 3-5 position can be stored to a pits (pit) by the super-resolution mode that reads the wavelength mark, so that optical record medium has four times storage volume.Yet in order to carry out aforesaid way, various accurate and accurate electronics, optics and plant equipment are indispensable, thus, this manufacturing cost that gets this kind optical record medium is significantly increased and cause and can't carry out.
For obtaining the optical record medium with bigger storage volume, industry proposes a kind of optical record medium that utilizes the three-dimensional data storage method, and it utilizes the storage volume of the storage area of increase depth direction with further lifting optical record medium.By the three-dimensional data storage mode, the data storage density of optical record medium can be promoted to 10
12Position/cubic centimetre improves the ability of optical record medium data storing significantly.This three-dimensional data storage mode mainly utilizes the part of the optical storage media refractive index with three-dimensional data figure to change the purpose that reaches access data.Its principle then is to read laser because of the birefringence that different refractivity caused and the variation of polarity by detecting, carries out the binary coding of data.
Yet, because caused diffraction of its sandwich construction of optical record medium and energy loss make the fluorescence signal strength that this optical storage media produced weaken.In order to detect so faint signal, certainly will use signal detector with more powerful laser and higher sensitivity, so more can't meet the needs of existing market to optical record medium.Therefore, under the prerequisite that does not increase processing procedure degree of difficulty and manufacturing cost, promoting the fluorescence signal strength of optical record medium, is the technical emphasis of needing research badly of present three-dimensional data storage.
