PURPOSE:To simplify a switching operation and a circuit, and to enable a sound signal to be added even in high speed search time, by constituting a device so as to obtain a high speed search by raising the readout clock frequency of the sound signal. CONSTITUTION:When a mode is switched to a high speed mode, first of all, it is decided that a state is a reproduction state, and next, the readout cycle T of a memory (RAM) is switched to a cycle Ts/n. And when it is not a video reproduction time, in other words, when a head is located on a sound track, a head is sent to a track where a still picture corresponding to said sound information is recorded, then the still picture being reproduced, after a write on a memory (RAM) is completed, and simultaneously, the sound signal is read out from the memory (RAM) with the clock cycle of Ts/n. Therefore, the still picture and the sound signal having the speed of n-times are outputted. When the sound signal is terminated, the head is moved to the next sound track, and the still picture and the sound signal are outputted continuously in a similar sequence.
