    摘要： The invention provides an information recording device, an information reproducing device, and an information recording medium capable of securely protecting copyright of main information, and preventing illegal access to the recorded main information. The information recording device (3) is provided with a medium unique information generating section (9) that generates second sub information by data-converting stamper unique information based on disc identification information that differs for each optical disc after transferring main information and first sub information from a stamper (1') having the main information and the first sub information recorded therein onto an optical disc (1), and a medium unique information recording section (10) that records the second sub information in the optical disc (1) having recorded therein in advance the main information and the first sub information in a form different from the forms of the main information and the first sub information.

    摘要： 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.

    摘要翻译： 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。
