ABSTRACT:
A multi-level optical recording medium according to the present invention is a multi-level optical recording medium (1) which is capable of recording record data according to multi-level recording that defines light reflection ratios of recording portions (12) into multiple levels by switching the irradiation amount of a recording laser beam between multiple levels, wherein light reflection ratio information enabling identification of a light reflection ratio dynamic range within which respective light reflection ratios of the recording portions (12) should be included is readably recorded. Due to this construction, when record data are recorded, it is only required to record the record data such that the respective light reflection ratios of the recording portions (12) are included within the light reflection ratio dynamic range identified from the light reflection ratio information, and it is unnecessary to perform the operation of checking the characteristics of the multi-level optical recording medium (1) prior to recording the record data. Therefore, it is possible to record the record data promptly and easily without wastefully using a data-recording area.
