Abstract
A hologram recording method includes generating light of a pattern in which a plurality of unit blocks, which include at least one pixel and express luminance, are arrayed, the pattern being sectioned into a region of a signal beam and a region of a reference beam, and being generated such that the region of the reference beam includes a plurality of unit blocks whose numbers of pixels are different; collecting the generated light at a common optical system, and illuminating it onto an optical recording medium; and recording, as a hologram, data which the signal beam expresses.
