摘要：

An optical infomation recording/reproducing apparatus (10) and an optical information recording/ reproducing method that record intormation using holography, wherein the optical information recording/reproducing apparatus (10) includes a signal generation unit (86) that generates two-dimensional data by two-dimensional encoding method in which a lower-limit value of a number of continuous ON/OFF pixels in an array in one direction of pixels in a two-dimensional spatial light modulator (308) is K(K‰¥2, K: natural number); and a pickup (11) that records the two-dimensional data generated by signal generation unit (86), on a hologram disc (1).
