In an optical disk reproducing device, through a provision of a control circuit, movement of focus point of laser beams is set at positions ahead or back to the focus position causing to enter into an automatic focus control loop, and a retry search signal for searching the focusing position is caused to be generated by the search signal generation means, thereby, a refocusing control in case when an automatic focusing servo loop can not be maintained can be started from the positions ahead or back to the focus position causing to enter into the automatic focus control loop.
