Technical Examples
  1. Disclosed are a method for recording address information on an optical recording medium, an optical recording medium including address information recorded thereon by the same method, and a method for detecting the address information recorded on the optical recording medium. The address information is recorded on the optical recording medium by such a procedure that physical address information of the optical recording medium is ASK (Amplitude Shift Keying)-modulated so as to convert the physical address information to a wobble signal, and then a wobble-shaped recording track is formed on the optical recording medium using the converted wobble signal, thereby recording the physical address information on the recording medium. Therefore, physical address information can be accurately decoded using a phase locked loop circuit and a wobble signal detecting circuit having a simple configuration, without reducing the data recording capacity of the optical recording medium.
