摘要：
A recording layer is formed on a substrate, and a high thermal conductor having a thermal conductivity higher than that of the recording layer is disposed inside a plurality of recording bit regions constituting the recording layer, respectively. Furthermore, the recording layer is formed with a separating portion which divides the recording layer into the plurality of recording bit regions. The separating layer is filled with a low thermal conductor having a thermal conductivity lower than that of the recording layer.
