A signal output method for reducing jitter and forming pits having stable
shapes on an optical information recording medium with high recording
density is provided. A write signal includes a write permission signal
including a repetition of write enable and pause intervals, and a write
data signal outputted during the write enable interval. The write signal
satisfies the formula Tf.sub.max-Tf.sub.min.gtoreq.0.01T, where
Tf.sub.max is an output interval of a first write data signal among write
data signals corresponding to a write permission signal immediately
subsequent to a pause interval when the pause interval of the write
signal is a maximum, Tf.sub.min is an output interval of a first write
data signal among write data signals corresponding to a write permission
signal immediately subsequent to a pause interval of the write signal
when the pause interval of the write signal is a minimum, and T is a
reference period.
