PROBLEM TO BE SOLVED: To provide an information recording method capable of reducing the difference in characteristics of reproduced signals between the case reproduced with a recording wavelength and the case reproduced with a reproducing wavelength, or between the case reproduced with a recorder and the case reproduced with a reproduction exclusive device. SOLUTION: The fluctuation of the optimum recording state due to the difference in resolution of the reproducing device is suppressed and the reproduction interchangeability is improved by such a manner that a ratio of the pulse emitting time Ttop+Tmp*(Twd-3) to the difference tstop-teend between the top pulse emission starting time tstop and the final pulse emission ending time teend is set to be 0.7 or larger so as to optimize the recording state to record the information. |
