光学数据记录介质及其读取装置、记录装置和制造方法
摘要：
一种盘形光学数据记录介质及其读取装置、记录装置和制造方法，所述光学数据记录介质具有用于利用光读和/或写数据的信号记录层，及设置在信号记录层上面的10μm至200μm厚的透明保护层。所述光学数据记录介质包括：从光发射到信号记录层的光入射表面侧的透明保护层的表面伸出的凸起。所述凸起设置在中心孔和当在信号记录层中读和/或写数据时夹持所述光学数据记录介质的夹紧区域之间的区域中。
摘要（英）：

A disc-shaped optical data recording medium has a signal recording layer for reading and/or writing data using light, and a 10 mum to 200 mum thick transparent protective layer disposed over the signal recording layer. The optical data recording medium includes a protrusion projecting from the surface of the transparent protective layer on the light-incidence surface side to which light is emitted to the signal recording layer. The protrusion is disposed in an area between a center hole and a clamping area where the optical data recording medium is held when reading and/or writing data in the signal recording layer.
