ABSTRACT:
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 Tfmax−Tfmin≧0.01T, where Tfmaxis 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, Tfminis 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.
