PURPOSE: A control method of optical recording regenerator is provided to increase performance of an optical recording regenerator by controlling a spindle with a target speed after detecting wobble signal previously when free running and executing wobble PLL. CONSTITUTION: A control information is read and output by detecting a wobble signal which is made a wobbling and formed at a track of a recordable data region at a point of time that an optical disk do not execute recording regeneration in a normal state. The control information is used to recording regeneration in a normal state. A wobble signal is executed detecting the wobble signal(202) if free running state, that is focus servo only is in state of ON(201). A spindle servo controls rapidly making a spindle up or down through the spindle motor after detecting rotation speed of the optical disk from wobble signal to be made a PLL(phase locked loop).
