PURPOSE: To remove a synchronization error and also to easily increase the number of channels, by making a subsidiary reproducing machine precede, executing the synchronizing reproduction, supplying its signal to the memory, and reading it out by delaying it by a synchronization error.
CONSTITUTION: A signal which has been recorded is brought to synchronizing reproduction in recording and reproducing machines 1, 2 at every channel. The reproducing machine 1 fetches an address of each block of a reproducing signa, supplies it to a synchronization error detector 4, and the reproducing signal is outputted to a reproducing signal output terminal 6. At the same time, the reproducing machine 2 fetches an address of each block of the reproducing signal, supplies it to the detector 4, and on the other hand, the reproducing signal is supplied to a memory 5. The detector takes a difference between the addresses supplied from the reproducing machines 1, 2, and a synchronizing error (k) is obtained. When said signal is read out from the memory 5 by delaying it by M+k(k<M) block portion, the synchronization error of the reproducing machine 2 which has preceded by M+k blocks is removed. In this regard, the number of channels is increased by adding a reproducing machine 8, a sychronization error detector 9 and a memory 10.
