发明名称 RECORDING/REPRODUCTION METHOD AND HOLOGRAM RECORDING MEDIUM
摘要 A recording/reproduction method of performing recording/reproduction of a hologram by illuminating a hologram recording medium, which has a recording layer in which information is recorded by interference fringes between signal light and reference light, with the signal light and/or the reference light as recording/reproduction light through an objective lens includes the step of: setting a focal position of the recording/reproduction light such that a distance from a surface of the hologram recording medium to the focal position of the recording/reproduction light is larger than a distance from the surface to a lower-layer-side surface of the recording layer and illuminating the hologram recording medium including an angle-selective reflective layer, which is formed below the recording layer and has a selective light reflection/transmission characteristic depending on a light incidence angle, with the recording/reproduction light the focal position of which has been set.
