Claim:
1. A holographic recording method in which an interference fringe between a reference beam and a signal beam modulated according to information regarding a plurality of hologram pixels is recorded on a holographic recording medium, the holographic recording method comprising: multiplexing-recording the interference fringe of the plurality of hologram pixels such that at least a part of the interference fringe recorded of neighboring hologram pixels of the plurality of hologram pixels is overlapped, the plurality of hologram pixels comprising a first hologram pixel and a second hologram pixel, and the interference fringe comprising a first interference fringe of the first hologram pixel and a second interference fringe of the second hologram pixel; and determining a multiplexing factor M that is greater than 1, wherein the multiplexing-recording comprises: wherein the holographic recording medium is exposed to light during an exposure time of t/M to record the first interference fringe, and wherein t denotes a time during which the holographic recording medium is exposed to light to record the first interference fringe without multiplexing.
