ABSTRACT:
A rewritable optical information recording medium includes a transparent substrate on which a groove is formed, and a recording layer on which frequency-modulated address information is recorded by wobbling the groove. The recording layer is provided on the transparent substrate. In the rewritable optical information recording medium, J(M)/M≦0.17 is satisfied where J(M) is relative jitter with respect to a basic clock T0and M is a degree of modulation of recorded signal. The relative jitter J(M) is given by J(M)=Tσ(M)/T0when Tσ(M) is jitter with respect to the degree of modulation M. The jitter Tσ(M) is caused in the demodulated address information which is one modulated according to mark length modulation.
