    Abstract: Sub-information necessary for reproduction of main information is recorded on an optical disc without deterioration of reading accuracy of the main information, so that illegal reproduction is prevented. After a concave and convex mark (MK) synchronizing with integer times a channel bit length is formed on optical disc (1) in accordance with modulated main information, a reflective film (IL) is formed on the concave and convex mark (MK). After the optical disc (1) is molded, a continuous or intermittent laser light, which has an interval that is longer than the longest mark in the concave and convex mark (MK) and is synchronous with integer times the channel bit length, is irradiated to the reflective film (IL) which, in turn, changes its chemical characteristic to form a recordable mark, so that the sub-information necessary for reproduction of the main information is recorded in a superimposition manner.

    Abstract translation: 主信息再现所需的子信息被记录在光盘上，而不会使主信息的读取精度降低，从而防止非法再现。 在根据调制后的主信息在光盘（1）上形成与整数倍通道位长同步的凹凸标记（MK）之后，在凹凸标记（MK）上形成反射膜（IL）。 在光盘（1）成型之后，照射具有比凹凸标记（MK）中的最长标记更长的间隔并且与通道位长度的整数倍同步的连续或间歇激光 到反射膜（IL），反过来它又改变其化学特性以形成可记录标记，从而以重叠方式记录重放主信息所需的子信息。

    Abstract: AN INFORMATION STORAGE MEDIUM ACCORDING TO THE PRESENT INVENTION HAS N INFORMATION STORAGE LAYERS (WHERE N IS AN INTEGER AND N ? 3), ON WHICH DATA CAN BE WRITTEN WITH A LASER BEAM AND WHICH ARE STACKED ONE UPON THE OTHER. EACH OF THE N STORAGE LAYERS HAS A TEST WRITE ZONE FOR DETERMINING THE RECORDING POWER OF THE LASER BEAM. WHEN THOSE N LAYERS ARE COUNTED FROM THE ONE THAT IS LOCATED MOST DISTANT FROM THE SURFACE OF THE MEDIUM ON WHICH THE LASER BEAM IS INCIDENT, THERE IS A BIGGER RADIAL LOCATION DIFFERENCE BETWEEN THE OUTER PERIPHERAL END OF THE INNER ONE OF THE TEST WRITE ZONES OF iTH AND (i+1)TH INFORMATION STORAGE LAYERS (WHERE i IS AN INTEGER THAT SATISFIES 2 ? i ? N-1) AND THE INNER PERIPHERAL END OF THE OTHER OUTER TEST WRITE ZONE THAN BETWEEN THE OUTER PERIPHERAL END OF THE INNER ONE OF THE TEST WRITE ZONES OF jTH AND (j+1)TH INFORMATION STORAGE LAYERS (WHERE j IS AN INTEGER THAT SATISFIES 1?j? i-1) AND THE INNER PERIPHERAL END OF THE OTHER OUTER TEST WRITE ZONE.

    Abstract: An information recording medium according to the present invention includes three or more information recording layers. Each of the plurality of information recording layers includes a test recording area usable for adjusting a recording condition. One of the plurality of information recording layers includes a reproduction-only management data area in which management data usable for managing the information recording medium is pre-recorded. One information recording layer includes a recordable management data area in which management data usable for managing the information recording medium is newly writable. Each of the other two or more information recording layers among the plurality of information recording layers includes a test recording area at a radial position overlapping the radial position of a part of the reproduction-only management data area. In the one recording layer including the recordable management data area, the recordable management data area is provided at two positions, i.e., one on the inner side and the other on the outer side to the test recording area.

    Abstract: Provided is an information recording medium which is compatible with a plurality of recording speeds and contains recording conditions of the recording speeds which have been recorded in advance. The recording conditions include: a parameter concerning a recording power for recording at each of the recording speeds and a parameter concerning a recording waveform; and other parameters concerning a recording power for performing a recording at a recording speed other than the aforementioned recording speeds by using a parameter concerning a recording waveform for performing a recording at the recording speed.
