ABSTRACT:
A holographic recording method, a holographic recording apparatus, a holographic recording and reproducing method, a holographic recording and reproducing apparatus, and a holographic recording medium for recording information in an angle multiplex fashion as a hologram in a first format in which either one of signal light and reference light branched out from a laser light source is made to cross the other in a recording layer at a predetermined incidence angle and the incidence angle is changed at a predetermined angular pitch, or in a second format of higher angular selectivity, wherein the incidence angle when recording information in the second format of higher angular selectivity can be adjusted to cover an incidence angle that satisfies the Bragg's condition when recording in the first format, thereby ensuring reproduction compatibility between media of different angular selectivities.
