A signal reproducing device for use in an optical disk apparatus adapted to irradiate an optical disk with light beams and detect a reproduction signal associated with a mark formed on the optical disk from light beams reflected by the optical disk and reproduce data recorded thereon on the basis of the reproduction signal. This signal reproducing device is provided with a first clock generating unit for generating a first clock corresponding to a leading edge of the mark, a second clock generating unit for generating a second clock corresponding to a trailing edge of the mark, a first sampling unit for sampling the reproduction signal according to the first clock, a second sampling unit for sampling the reproduction signal according to the second clock and a selection unit for selecting one of outputs of the first and second sampling unit. Thereby, reproduction signals can be sampled with optimum timing at all times.
