Abstract:
An apparatus for reproducing program data recorded on an optical disc at a multiple velocity, said apparatus comprising:storing means for storing data which relates to a rotation velocity for normal and multiple velocity reproductions of the optical disc and to a reproduction velocity of the program data recorded on said optical disc;control means for detecting whether or not a reproduction mode signal generated by a user's key operation is either the normal velocity reproduction or the multiple velocity reproduction, for reading out the rotation and the reproduction velocity data corresponding to the detected reproduction mode signal from said storing means to output rotation and reproduction velocity data signals;clock generating means for generating a reference clock signal;velocity control means for receiving the reference clock signal and for dividing the reference clock signal based on the rotation and reproduction velocity data signals to output rotation and reproduction velocity control signals and a memory control signal corresponding to the detected reproduction mode signal;rotating means for receiving a present reproduction velocity signal and for rotating said optical disc at a rotation velocity determined by the present reproduction velocity signal and the rotation velocity control signal;reproducing means for reproducing the program data recorded on said optical disc at a reproduction velocity determined by the reproduction velocity control signal and for providing said rotating means with the present reproduction velocity signal which represents a presently-reproduced velocity of the program data; anda memory for storing the program data from said reproducing means and for outputting the stored program data in response to the memory control signal.
