Pdir (ns) is a predetermined width shortened when a pulse width of the same length as that of a bit to be recorded is modulated with a pulse width at the time of recording, and dmdm (ns) is a minimum pulse width of the pulse width of the same length as that of the bit to be recorded. Thus, a signal having excellent recording/reproducing characteristics can be recorded on a dye recording layer type optical disk with a reflecting layer.
