A disc playback apparatus is configured to reproduce information by
demodulating and decoding a radio-frequency signal obtained by receiving
reflected light of a beam applied to a recording surface of a removable
disc when the disc is loaded in the disc playback apparatus. The
apparatus includes a disc format determining unit adapted to determine
the format of the loaded disc, a high-frequency compensation unit adapted
to compensate for a high-frequency component of the radio-frequency
signal, a low-frequency compensation unit adapted to compensate for a
low-frequency component of the radio-frequency signal, and a control unit
adapted to determine which of the high-frequency compensation unit or the
low-frequency compensation unit is to be used to compensate for a
frequency characteristic of the radio-frequency signal based on the
determined disc format.
