Filed: 2011-04-01
Abstract: In the conventional skill, a BCA (Burst Cutting Area) cutter is typically used to proceed with writing in BCA data, after forming a user data area. However, such a method has to arrange respective steps for corresponding to the formation of BCA in the optical disk manufacturing step, resulting in a heavy burden to the optical disk manufacturer in view of the manufacturing labor hour as well as the manufacturing cost of the optical disk. The use of a groove formation method same as the user data area is able to eliminate the BCA manufacturing step. In addition, by setting the groove depth of the BCA part to be about one fourth of the wavelength for recording reproduction laser, it is able to further increase the modulation degree of the BCA part, so as to be suitable for a detection method that is the same as the conventional BCA.
