摘要
A holographic disc recording medium records a hologram over the entire holographic disc recording medium by using a conical reference beam for recording. A hologram recorded image includes recorded images of a plurality of data pages including a plurality of pixels arranged in an approximately rectangular array. A cylindrical reference beam for reading having coherent light having an approximately cylindrical wavefront shape with a small curvature is used to minimize the mismatch in wavefront shapes between the reference beam for recording and reference beam for reading.
