<p>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 T0 and M is a degree of modulation of recorded signal. The relative jitter J(M) is given by J(M) = T sigma (M) / T0 when T sigma (M) is jitter with respect to the degree of modulation M. The jitter T sigma (M) is caused in the demodulated address information which is one modulated according to mark length modulation. <IMAGE></p> |
