摘要： A disk has a burst cutting area (BCA) formed by a crystalline portion and an amorphous portion, and the disk is an optical disk (L-H medium) in which the reflectance of the crystalline portion is lower than that of the amorphous portion. The width Wcry of the crystalline portion in the BCA is lower than half the data period Wdat. Therefore, the average level of a BCA reproduction signal is unchanged regardless of whether the optical disk is an H-L medium or an L-H medium, so that focus control and reproduction of a BCA code can be performed even if a parameter of a circuit is a default.
摘要翻译： 盘具有由结晶部分和非晶体部分形成的突发切割区域（BCA），并且该盘是结晶部分的反射率低于非晶部分的反射率的光盘（L-H介质）。 BCA中结晶部分的宽度Wcry低于数据周期Wdat的一半。 因此，无论光盘是HL介质还是LH介质，BCA再现信号的平均电平都不变，因此即使电路的参数是默认值，也可以执行BCA代码的聚焦控制和再现 。
