ABSTRACT:
In a method for synchronizing recording and reproducing devices including a master device and a slave device, during a recording mode and in a state where reference clock of the slave device is synchronized with reference clock of the master device, position information which is synchronized with the reference clock of the master device is recorded commonly in both the master and slave devices and information to be recorded is simultaneously recorded in both the master and slave devices. During a playback mode, the master device and the slave device reproduce the position information respectively at their own reference clocks and cause internal counters provided in the respective devices to perform counting at their own reference clocks and to be reset at a predetermined period of the position information reproduced in the respective devices. The slave device compares a reproduced value of the position information and a count value of the internal counter provided by the master device with a reproduced value of the position information and a count of the internal counter of the slave device and thereby causes the reference clock frequency of the slave device to change so that differences between the values of the master device and those of the slave device become predetermined values.
