发明名称 Rotary recording medium reproducing apparatus capable of performing high-speed search operation
摘要 A rotary recording medium reproducing apparatus comprises a transferring circuit for transferring a reproducing element for reproducing a rotary recording medium, along a radial direction of the rotary recording medium, where the transferring circuit transfers the reproducing element at a normal speed during a normal reproduction mode, and transfers the reproducing element at a speed higher than the normal speed during a search mode in which a search is performed with respect to a desired reproducing position on the rotary recording medium, a synchronizing signal generating circuit for generating a synchronizing signal consisting of a horizontal synchronizing signal and a vertical synchronizing signal synchronized with a synchronizing signal within a video signal reproduced by the reproducing element during the search mode, a switching circuit for selectively passing the video signal reproduced by the reproducing element and the synchronizing signal obtained from the synchronizing signal generating circuit, and a control circuit for controlling and switching the switching circuit so that the switching circuit passes the video signal reproduced by the reproduced element during the normal mode and passes the synchronizing signal obtained from the synchronizing signal generating circuit during the search mode. The signal passed through the switching circuit is supplied to a television receiver.
