Patent ID: 7321534

Claim:
A signal output method comprising: providing a write permission signal including a repetition of a write enable interval and a pause interval; providing a write data signal to be output during the write enable interval; outputting a write signal including the write permission signal and the write data signal; and writing information to an optical information recording medium by using the write signal, wherein Tfmax denotes 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 in a case in which the pause interval of the write signal is a maximum, Tfmin denotes an output interval of a first write data signal among the write data signals corresponding to a write permission signal immediately subsequent to the pause interval of the write signal in a case in which the pause interval of the write signal is a minimum, T denotes a reference period, and wherein the write signal is outputted so that Tfmax, Tfmin and T satisfy the following formula (1): Tf max− Tf min≧0.01 T , and Formula (1): wherein Tfmax and Tfmin actively write information to the recording medium by forming a recording pit thereon.
