A reproducing apparatus, reproducing method, recording and reproducing apparatus, recording and reproducing method, recording apparatus, and recording method are provided. A reproducing apparatus reproduces data from a hologram recording medium in which data inserted with syncs at predetermined intervals is recorded in each predetermined page unit by interference fringes of reference light and signal light includes a reference-light irradiating unit that irradiates the reference light on the hologram recording medium, a signal readout unit that receives diffractive light corresponding to the data recorded on the hologram recording medium, a sync-position detecting unit that detects a position of a detection object sync on the basis of positions of plural syncs selected with the position of the detection object sync as a reference, and an amplitude-value calculating unit that specifies positions of respective recording pixels in the readout signal on the basis of the positions of the respective syncs detected by the sync-position detecting unit and calculates amplitude values of the respective pixels.
