METHOD OF AND DEVICE FOR RECORDING INFORMATION, RECORD CARRIER, AND DEVICE FOR READING THE RECORDED INFORMATION

摘要

Method of and device for recording information, record carrier, and device for reading the recorded information. A method of and device for recording an information signal (Vc) on a record carrier (1) are revealed. The information words of the information signal are converted into code words (200) comprising a variable number of bits of a first logic value ("1"). The number of consecutive bits of the first logic value is at least equal to P. The number of consecutive bits of the second logic value ("0") is at least Q, P being an integer greater than or equal to 1 and Q being an integer greater than P. The code words are selected in such a way that for information words of successive values the associated code words differ for only one bit. During recording an elementary mark (54) is formed on the record carrier for every bit of the first logic value Moreover a read device for the record carrier thus obtained is described. (Fig.8).
