An optical medium reproduction device optically reproduces data in an optical medium having a plurality of tracks formed thereon, the optical medium reproduction device comprising: an optical filter on which an optical beam returning from the optical medium is incident to form a plurality of signals having mutually different bandwidths spatially and optically in the tangential direction and the radial direction; a calculation unit for forming second signals with a plurality of channels by calculating a plurality of first signals formed by the optical filter; and an electrical filter on which each second signal is incident and which acquires a reproduction signal by processing the second signals.
