ABSTRACT:
An apparatus, a signal processing circuit and a method for reproducing data stored on a disc to prevent a buffer memory from experiencing overflow/underflow. Writing information data read from the disc to the buffer memory is performed in response to a reproduction stage clock, and reading from the buffer memory is in response to a signal processing stage clock. The signal processing stage clock for reading information data may be derived from the reproduction stage clock.
