Abstract

An apparatus for reproducing program data recorded on an optical disc at a multiple velocity without a deterioration of a screen quality is disclosed. Storing section stores data which relates to rotation and reproduction velocity for normal and multiple velocity reproductions of the optical disc. Maincontroller checks whether or not a reproduction mode signal indicates the multiple velocity reproduction, and outputs rotation and reproduction velocity data signals corresponding to the checked reproduction mode signal. Velocity controller outputs rotation and reproduction velocity control signals and a memory control signal corresponding to the checked reproduction mode signal based on the rotation and reproduction velocity data signals. Rotating section rotates the optical disc at a rotation velocity determined by a present reproduction velocity signal and the rotation velocity control signal. Reproducing section reproduces the program data at a reproduction velocity determined by the reproduction velocity control signal and provides the present reproduction velocity signal to the rotating section. Memory stores the program data from the reproducing section and output the stored program data in response to the memory control signal. The rotation velocity of the optical disc and the reproduction velocity of the program data are variably controlled. The reproduced program data is stored in the memory and the stored program data is sequentially outputted. Consequently, the apparatus can prevent the deterioration of the screen quality caused by reproducing the program data recorded on the optical disc at the multiple velocity.
