By adopting the detected capstan phase as a phase control information, the time required for {HEAD ~ the mode} of {TAIL ~ the system} to be changed from the stop mode to the reproducing mode or from the searching mode to the reproducing mode, namely while the mode of the system is changed from the speed variation mode to a normal speed mode is reduced, so that it is possible to obtain a more stable reproducing operation at a high speed
