An apparatus for recording information in an optical-information recording media by holography includes a signal-light irradiation unit, a reference-light irradiation unit, a reference light angle adjustment unit, and a positioning unit for positioning irradiation positions of the signal light and the reference light. The optical-information recording media is divided into N (N≧2) recording regions, M multiplexed information can be recorded in the respective recording regions by the reference light angle adjustment unit which changes the angle of the reference light at M angles (θ1, θ2, . . . , and θM) corresponding to a multiplexing number (M≧2), management information for the M multiplexed information is multiplexed and recorded in the same recording region as a-th information (1≦a≦M) with a reference light angle θa, and the management information on all the N recording regions are recorded at a common reference light angle.
