Abstract:
1. A recording/reproducing device for (a) reading out, from an information recording medium, recording parameters which are contained in a predetermined region of the information recording medium and which are for pulse sequences for forming recording marks in accordance with recording information, and (b) performing recording operation by using the recording parameters, said recording/reproducing device comprising: an optical head for irradiating a laser onto the information recording medium so as to record/reproduce the recording marks on/from the information recording medium; a storage section for storing a first look-up table and a second look-up table which are read out from the information recording medium; and a recording parameter setting section for setting, as the recording parameters of the pulse sequences, the recording parameters read out from the first look-up table and the second look-up table, which are stored in the storage section, the pulse sequences including: the second predetermined recording mark length is longer than the first predetermined recording mark length, and said optical head forming said recording marks on the information recording medium on the basis of the recording parameters set by the recording parameter setting section.
