ABSTRACT:
A method of recording a hologram on a recording medium composed of a substrate and a recording material coated as a thin layer on the substrate, the recording medium being transparent or semitransparent with respect to light to which the recording medium is exposed. A value B, B/A, B/Bo, A/B, or Bo/B is established where A is the intensity of the light at a surface of the recording medium, B is the intensity of the light that has passed through the recording medium, and Bo is the intensity of the light that has passed through the recording medium immediately after the recording medium has started to be exposed to the light. The recording medium is exposed to the light until the established value is equalized to a preset value. The exposure of the recording medium is stopped when the established value is equalized to the preset value.
