発明の名称 (英語) OPTICAL INFORMATION RECORDING/REPRODUCTION METHOD AND DEVICE
発明の概要(英語) It is possible to provide a new optical information recording/reproduction method and a device which can realize a small-size large-capacity optical memory having a characteristic equivalent to or higher than a hologram memory. The optical information recording/reproduction device includes: a recording light generation device (51) which generates a recording light (55) in a polarized state having two polarized components orthogonally intersecting each other with a phase difference at an arbitrary polarization base; a reproduction light generation device (61) which generates a reproduction light (65) in a polarized state having only one polarized component at an arbitrary polarization base; a recording medium (71) which records optical information owned by the recording light (55) and reproduces the optical information recorded by the reproduction light (65); and optical information detection device (polarimeter (81)) which extracts an information light (72) after being applied to the recording medium (71) and detects the light as optical information. Provided is also an optical information recording/reproduction method using the device.
