In an evaluation device and an evaluation system, the level of base power is set higher than that in an optimal recording condition at a set room temperature and lower than the level of bias power. In particular, the level of the base power is set so that the jitter value of a recording mark and a blank, which is formed in a required high temperature environment, during reproduction in the high temperature environment becomes minimum. By evaluating the recording characteristic of a recording mark and a blank formed by irradiation of recording laser light in the form of a pulse train, the recording characteristic of an optical recording medium in high-speed recording in high temperature environment is evaluated.
