Method for wobble addressing on optical disc using an amplitude shift keying rule

摘要

The present invention relates to a wobble addressing method of the optical disc using the amplitude shift keying method,, DVD-RW a recordable optical disc such as, for providing such clock required for spindle servo control operation or data recording / reproduction, the physical address information to be recorded in advance, by using the ASK (Amplitude Shift Keying) modulation scheme, the groove of the optical disc (Groove ) recorded by the wobble shape or in, or by using a pre-coding (Pre-Coding) scheme is ASK-modulated by the physical address information of a predetermined recording size wobble unit is recorded on the optical disc with the wobble shape of the groove, to be the actual data record maintaining the data as the recording capacity, while using a simplified common wobble phase-locked loop, would be very useful to be able to correctly decode the inventors physical address information.
