    摘要: An object of the present invention is to provide an optical disk reproducing method and apparatus which allows for influence on focus servo control and tracking servo control involved in outputting voice information. The optical disk reproducing apparatus includes an optical pickup, a tracking servo control for causing the optical pickup to trace a track on the optical disk, a focus servo control and a pair of speakers for outputting reproduced voice information to the outside. When an information determining unit determines that the reproduced information includes voice information, the tracking servo control and the focus servo control are operated so as to provide a servo characteristic suitable for reproduction of voice information by the speakers to thereby reproduce information in the optical disk.
