摘要： On a recording layer (12) of a disc-shaped optical recording medium (10), a plurality of virtual recording cells (40) are assumed contiguously in a spiral or concentric fashion in a groove (16). The irradiation time of the laser beam is modulated in five stages or more for each of the virtual recording cells (40) in response to information to be recorded, thereby forming recording marks (48A to 48G) of different sizes in five stages or more. The optical reflectivity of the virtual recording cell (40) is modulated in multi-stages to thereby vary the reflection level of a reading laser beam for reading operations in five stages or more. The length of the virtual recording cells (40) in the rotational direction of the disc is set to be equal to that of an arc having the same center angle with respect to the center of the disc.

摘要： 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.

The method for recording data in an optical recording medium according to the present invention is constituted so as to project a laser beam onto a write-once type optical recording medium including a light transmissible substrate 11 and a recording layer 21 and form a recording mark in the recording layer 21, thereby recording data therein and the method for recording data in an optical recording medium comprises steps of determining a pulse train pattern so that a level of a pulse is switched from the level corresponding to the level of the recording power Pw to the level corresponding to the level of the bottom power Pb in accordance with the length of a blank region to be formed immediately after formation of a first recording mark and the length of a second recording mark formed subsequent to the formation of the first recording mark, modulating the power of laser beam in accordance with the thus determined pulse train pattern, projecting the laser beam onto the optical recording medium and forming the first recording mark. According to the present invention, since the pulse train pattern is determined so that the level of a pulse of a pulse train pattern used for forming a first recording mark is switched from the level corresponding to the level of the recording power Pw to the level corresponding to the level of the bottom power Pb in accordance with the length of a blank region to be formed immediately after formation of the first recording mark and the length of a second recording mark formed subsequent to the formation of the first recording mark, the first recording mark can be formed so that the length thereof is not influenced by the length of the blank region to be formed immediately after formation of the first recording mark and the length of the second recording mark and it is therefore possible to form a recording mark having a desired length, thereby recording data, and reduce jitter of a reproduced signal.
