摘要： The present invention was made to improve the strength, such as heat resistance, of a disc comprising a biodegradable resin. The optical disc according to the present invention is formed by bonding two substrates, at least one of the substrates having an information recording area. One substrate disposed on a light incident side of the optical disc is composed of a biodegradable resin that is uncrystallized and allows light to transmit therethrough. Another substrate disposed away from the light incident side of the optical disc is composed of the biodegradable resin having higher crystallinity than that of the substrate disposed on a light incident side of the optical disc.

摘要： When recording a recorded signal consisting of “01011001110” in a magnetooptical recording medium, (1,1) corresponding to a domain of 2T is converted to (1,0,1), and (0,0) is converted to (0,1,0) in the recorded signal. In other words, the first “1” of (1,1) is converted to unit bits “1,0” and the first “0” of (0,0) is converted to unit bits “0,1”. Similarly, the first “1” of (1,1,1) corresponding to a domain of 3T is converted to unit bits “1,0”, and the second “1” is converted to unit bits “1,0”. “1” or “0” of the final unit bit is not converted but recorded as such. Consequently, a signal can be correctly reproduced by extension ally transferring domains having different domain lengths from a recording layer to a reproducing layer under the same reproducing conditions.
摘要翻译：当在磁光记录介质中记录由“01011001110”组成的记录信号时，对应于2T的域的（1,1）被转换为（1,0,1），（0,0）被转换为（0， 1,0）记录信号。换句话说，（1,1）的第一个“1”被转换为单位比特“1,0”，（0,0）的第一个“0”被转换为单位比特“0,1”。类似地，对应于3T的域的（1,1,1）的第一“1”被转换为单位比特“1,0”，第二“1”被转换为单位比特“1,0”。最终单位位的“1”或“0”不转换而是被记录。因此，通过在相同的再现条件下将具有不同域长度的域从记录层延伸到再现层，可以正确地再现信号。
