摘要： A method of generating and allocating codewords includes allocating one of two selectable codewords b1 and b2 as codeword “b” when a preceding codeword “a” and a following codeword “b” form a code stream X, in which the codewords b1 and b2 have opposite INV values which are parameters indicating whether the number of ‘1s’ contained in a codeword is an odd number or an even number. When the code stream of the preceding codeword “a” and the following codeword b1 is X1, and when the code stream of the preceding codeword “a” and the following codeword b2 is X2, the codewords are allocated such that the INV values of X1 and X2 are maintained to be opposite when the preceding codeword “a” or the following codeword b1 (b2) (b1 or b2) should be replaced by another codeword in compliance with a predetermined boundary condition given between codewords. The codewords are allocated so that a DC suppression capability of the code stream can be maintained.

摘要： A code modulation and demodulation method includes removing a DC component of a code stream to be modulated when source data is recorded on an optical information storage medium and controlling a suppression of the DC component contained in the code stream when the source data is converted into a codeword to be recorded on an optical information storage medium. The method includes determining a control timing to suppress the DC component of the code stream to which the source data are converted, performing a code conversion at each control time for the DC component so that the code stream branches into a pair of branch code streams one of which extends in a direction where a running digital sum (RDS) of the code stream increases, and another one of which extends in the direction where the RDS of the code stream decreases, and selecting the path of the code stream that has a most bounded path around RDS ‘0’ from the paths of the branch code streams each control time. By performing a regular DC suppression control when the source data is converted, and by selecting one of the branch code streams when the DC suppression control is performed, more DC components in the code stream can be effectively removed.

摘要： A clock signal generating system using a wobble signal and a data reproducing apparatus, has a first block to detect a frequency error signal or a phase error signal from the RF signals on the recording medium and to output the detected frequency error signal or the detected phase error signal. A second block detects a wobble error signal from the wobble signals on the recording medium and outputs the detected wobble error signal. A clock generating unit generates a clock signal using the detected frequency error signal or the detected phase error signal of the second block when the RF signals have an error, and using the detected wobble error signal of the first block when the wobble signals have an error.
