Abstract:
A disc reproducing apparatus, comprising:an optical pickup for reading a signal from a disc; two clock signal reproducing circuits for reproducing clock signals so as to reproduce data from the signal read by said optical pickup, said two clock signal reproducing circuits having different capture ranges; two signal processing circuits for reproducing data with the clock signals reproduced from said two clock signal reproducing circuits, said two signal processing circuits being disposed corresponding to said two clock signal reproducing circuits; selecting means for selecting reproduction data that has been correctly reproduced by one of said two signal processing circuits; and range shifting means for shifting the capture range of the clock signal reproducing circuit corresponding to a first signal processing circuit of said two signal processing circuits when said selecting means selects reproduction data reproduced from a predetermined one as a second signal processing circuit of said two signal processing circuits.
