PURPOSE: A method of addressing wobble of an optical disk using an amplitude shift keying method is provided to record physical address information required to be recorded in advance in a groove of the optical disk in a wobble pattern using ASK method. CONSTITUTION: Physical address information of a recordable optical disk is modulated into a pulse signal using amplitude shift keying method. The modulated pulse signal is recorded in a groove of the optical disk in a wobble pattern. The physical address information is pre-coded in a wobble unit having a predetermined recording size. The pre-coded physical address information is modulated into a pulse signal using ASK method, and then the modulated pulse signal is recorded in the groove of the optical disk in a wobble pattern.
