Abstract
An information recording medium includes a track on which a data sequence is recordable, and at least one of a PIC area in which a recording condition for recording the data sequence on the track is recorded. The recording condition includes a parameter for adjusting a position of a trailing end of a cooling pulse in a recording pulse waveform for forming the recording mark. The parameter is classified using a combination of a length of the recording mark, a length of a first space located adjacently previous to the recording mark and a length of a second space located adjacently subsequent to the recording mark. A recording apparatus is provided for recording a data sequence on an information recording medium based on the recording condition recorded on the information recording medium. An evaluation apparatus is provided for evaluating an information recording medium having the recording parameter recorded thereon.
