Patent number: 7092329Abstract: A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, a method and circuit for detecting the wobble address and a recording medium therefor. Groove tracks are classified into odd groove tracks and even groove tracks. Address information indicating physical identification information is phase modulated using wobble signals having a predetermined phase difference between two adjacent groove tracks, and recorded in each groove track so that address information modulated using the wobble signals having the phase difference of 90° between adjacent two groove tracks can be a quadrature phase shift keying (QPSK) signal. Accordingly, a larger amount of data can be recorded on the recording medium, and since an interval in which a wobble signal disappears is not caused, recovery of a wobble clock signal can be advantageously performed.Type: GrantFiled: March 22, 2004Date of Patent: August 15, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-wan Ko, In-sik Park, Kyung-geun Lee, Du-seop Yoon, Seong-sin Joo, Jae-seong Shim, Byoung-ho Choi, Byung-in Ma, Young-jin Ahn, Tatsuhiro Otsuka
