ABSTRACT:
An optical recoding carrier and an information recording method applying an amplitude shift keying (ASK) method or further a DC-biased ASK method are provided, wherein at least one periodically undulated section and at least one non-periodically undulated section are formed on the optical recording carrier to indicate specific information. The information recording method can be embodied as an addressing method of an optical disk for recording address information of tracks of the optical disk. A continuous track structure is provided on the optical recording carrier to save the available recording space and improve the information reading precision of the optical recording carrier. Furthermore, a signal generating apparatus and an information reading apparatus applied in the information recording method are provided.
