    摘要: An allocating method of allocating a run length limited (RLL) code having enhanced direct current (DC) suppression capability, modulation and demodulation methods, and a demodulation apparatus are provided. In order to control DC suppression, a pair of code groups having suppression controlling capability are allocated, and a (1, 8, 8, 12) code having DC suppression capability, in which a code word of the pair of code groups has the sign of code word sum value (CSV) parameter, which represent DC value in a code word, and the characteristic of an INV parameter, which predicts the transition direction of digital sum value (DSV) of the succeeding code word, both opposite to those of the code word which belongs to the other code group and corresponds to the same source code, is used and is appropriate to high-density optical disc system.

    摘要: A method of recording data on a compact disc is provided includes modulating the data of 1 byte to p-channel bits, recording the modulated data when a minimum mark length is greater than 0.5 μm and smaller than 1.0 μm, p/q is greater than 4.5 and smaller than 8 when the minimum mark length corresponds to q-channel bits, and a format efficiency is greater than 0.6 and smaller than 1.0. Thus, data can be recorded on an existing compact disc at a higher density.

    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.
