    • The present invention provides an optical recording medium that includes a recording layer composed mainly of an organic compound and can utilize blue-violet semiconductor laser light (390 to 420 nm in wavelength) as recording/reproducing laser light. The present invention also provides an optical recording/reproducing method using the optical recording medium. The optical recording medium 1 comprises at least a supporting substrate 2; a recording layer 3 on the supporting substrate 2, the recording layer 3 containing an organic compound as a major component; and a light-transmitting layer 5 on the recording layer 3, the light-transmitting layer 5 being capable of transmitting laser light with a wavelength of 390 to 420 nm for recording and reproducing information. The organic compound in the recording layer 3 includes a trimethine cyanine dye that has the minimum value nmin of its refractive index n (real part of the complex refractive index) within the range of 370 to 425 nm and has a refractive index n of 1.2 or lower with respect to the wavelength of the recording/reproducing laser light. The organic compound, when absorbing the laser light, melts or degrades to bring about a change in the refractive index, thereby effecting recording of the information.

    • 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.
    • 根据本发明的多级光学记录介质是能够根据将记录部分(12)的光反射率定义为多个等级的多级记录来记录记录数据的多级光学记录介质(1) 通过切换记录激光束在多个等级之间的照射量,其中可以记录能够识别需要包含记录部分(12)的各个反射率的光反射比动态范围的光反射率信息。 由于这种结构,当记录数据被记录时,只需要记录记录数据,使得记录部分(12)的各个反射率被包括在从光反射比信息所识别的光反射比动态范围内 ,并且不需要在记录记录数据之前执行检查多级光学记录介质(1)的特性的操作。 因此,可以快速,容易地记录记录数据而不浪费地使用数据记录区域。
