Provided is a signal reproducing circuit for an optical disc player comprising a multidivisional photodetector with photoelectric converting elements in a preceding side and photoelectric converting elements in a succeeding side relative to a proceeding direction of pits of an optical disc, a variable delay circuit for delaying outputs from the photoelectric converting elements in the preceding side, a circuit for detecting a time difference between an output from the photo electric converting elements in the succeeding side and an output from the variable delay circuit, and a circuit responsive to an output from the time difference detecting circuit for changing a delay time of the variable delaying circuit. The signal reproducing circuit further comprises a,circuit for amplifying and correcting high frequency components of signals reproduced by the photo detector in response to the output from the time difference detecting circuit. This structure extends reproduced frequency band, improves high fre~uency characteristic of the video signals reproduced from the optical disc and supplies video signals having superior fre~uency characteristics. -69 ~ |
