摘要： 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 address information indicating physical identification information is phase modulated using a wobble clock signal and recorded in one of the two walls of a groove track, and land address information is phase modulated using a wobble clock signal obtained by shifting the phase of the former wobble clock signal and recorded in the other wall. That is, address information is phase modulated and recorded in each track using the wobbles having a phase difference of 90° between adjacent tracks so that a sum of wobble signals from the adjacent tracks can be a quadrature phase shift keying (QPSK) signal. Therefore, more data can be recorded in 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.

摘要： 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. A wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a simple carrier are recorded in each groove track by way of time division multiplexing. Groove tracks are divided into odd groove tracks and even groove tracks, and a wobble carrier and wobble address information are alternately recorded in each groove track and between odd and even groove tracks such that the wobble address information is not recorded in a section of an even groove track corresponding to a section of an odd groove track in which the wobble address information is recorded. Therefore, interference between wobble signals of adjacent tracks can be removed, and a method and a circuit for detecting a wobble address can be simplified.

摘要： A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, method and circuit for detecting the wobble address and a recording medium therefor. When addressing physical identification information on a recording medium, which has land and groove tracks in which data can be recorded, using wobbles, a wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a carrier are repeatedly alternatively recorded on both walls of either of a groove track and a land track by way of time division multiplexing. Accordingly, land and groove addresses can be detected by the same method, and the land track can be easily discriminated from a groove track by making the sizes of the addresses different in the land and groove tracks.

摘要： A recording medium for storing attribute information in a basic recording unit and a method of identifying data using the attribute information. On the recording medium, the attributes such as sector format, tracking method, reflectivity, area type, data type, and the number of layers of a sector are stored. For digital versatile disc-recordables (DVD-Rs), digital versatile disc-rewritables (DVD-RWs) and digital versatile disc-random access memory (DVD-RAM) on which data can be recorded and reproduced a multitude of times, information is stored relating to the attributes of a sector, which is a basic recording unit. In particular, information relating to data type, which represents whether the data is rewritable data, read-only, or linking data, can be stored in data identification data (DID) areas or identification data (ID) areas, which is positioned at the fronts of the sectors for representing all information relating thereto. Using combinations of the attribute information, it can be determined whether the data is linking data, and if not linking data, whether the data is read only or rewritable. Accordingly, consistency among optical recording media of the DVD-type discs is maintained.

摘要： 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.
