As can be seen, the measurement issues for the next generation formats go substantially beyond simply working with smaller features. The coding concepts, the relationships between measurements and playability, and the links between measured effects and their manufacturing-process causes, are all unique.

So, for BD, we have Random Symbol Error Rate (R-SER), Burst Error Max, and Max total length of burst errors.

CDRInfo will present the first digital error measurements on the recorded BD-R and BD-RE media in the final version of this review.

The recordable layer of a Recordable Blu-ray Disc, employs either organic or inorganic materials. For a single-layer Recordable Blu-ray Disc, the thickness from the disc surface to the recording layer is 100 µm.

For example, Fuji Photo Film Co., Ltd. has successfully demonstrated BD-R that can be readily put into commercial production using organic materials. Furthermore, TDK has realized BD-R discs using inorganic materials (a Cu alloy layer and a Si layer). In addition to the type of inorganic materials used by TDK, it is also possible to use write-once phase change materials.
