Abstract
A laser disk player performs a pause operation using a frequency generation (FG) pulse, frame address data read out from a disk and a vertical sync signal. A memory stores the frame address data read out at the time when a pause key signal is inputted. A microprocessor controls the pickup to jump back one track to the previous track and compares the currently read-out frame address data with the frame address data stored in the memory, to check the operation state of the frequency generator. If it is judged that the frequency generator for generating the FG pulse is operating abnormally, the microprocessor receives a vertical sync signal and controls the one-track jump operation of the pickup until the frame address data at a time of the pause is larger than or is equal to the frame address data read out via the one-track jumped pickup. Thus, the laser disk player performs a pause function reliably even if the frequency generator for generating the FG pulse operates abnormally.
