It is possible to provide a new information recording/reproduction method and a device which can realize a small-size large-capacity memory having a characteristic equivalent to or higher than a hologram memory. The optical information recording/reproduction device includes: recording light generator () which generates a recording light () in a polarization state having two mutually orthogonal polarization components with a phase difference at an arbitrary polarization base; reproduction light generator () which generates a reproduction light () in a polarization state having only a single polarization component at a arbitrary polarization basis; recording medium () in which optical information is recorded by recording light () and the recorded optical information is reproduced by reproduction light; and optical information detector (polarimeter) which retrieves information light () after being applied to recording medium () and detects the light as optical information. Provided is also an optical information recording/reproduction method using the device.
