A mask for recording holographic data, a manufacturing method therefor, and a method for recording the holographic data are provided to maximally and stably secure a dynamic range in a holographic data storing medium and further improve data recording efficiency by preventing an interference fringe which does not wish from being generated in a substrate because a reflected reference beam is inputted to the substrate again. Inter-different beams are inputted to one side and the other side of a transparent substrate(100). A certain pattern is patterned in the one side of the transparent substrate(100) to form a beam blocking film(200). The beam blocking film(200) absorbs the beam progressed to an area except for the certain pattern and blocks the progress of the beam. |
