ABSTRACT:
A method of recording a binary information signal on a record carrier having a radiation-sensitive information layer. The information signal is encoded in such a way that at least n (n.gtoreq.2) consecutive bit cells are of the same type. This information is recorded as pattern of unitary recording marks on the record carrier. Each unitary recording mark then corresponds to a number of m bit cells of the same first type in the information signal, where 1<m.ltoreq.n. A greater number of consecutive bit cells of said first type is represented by a plurality of unitary recording marks which are at least contiguous but which preferably overlap each other.
