%X Through analyzing physical addressing mode of volume holographic data storage(VHDS),two-dimensional addressing strategy of logical block address was given,by which the data-block of the file was allocated.By researching the continuity of file data-block allocation on two-dimensional logical block address,the concepts of "sequence continuity" and "stochastic continuity" were presented. Based on allocation quadruple-tree which was adopted as framework of the twodimensional logic area,the allocation algorithm for multiple block was designed.On the prototype system of VHDS,testing of the allocation strategies of data-block in the "file" level was made.The testing results prove that two-dimensional allocation strategy can make file data-blocks to be allocated more consecutive.
