{{Infobox media

Each Nintendo optical disc contains a Burst Cutting Area (BCA) mark, a type of barcode that is written to the disc with a YAG laser. Another example of DVD-like media with BCA marks is the discontinued DIVX format.

A BCA mark is visible to the naked eye. It should not be confused with the IFPI mark that is on all optical discs. BCA is described in Annex K of the physical specification, and can be seen between radius 22.3±0.4 mm and 23.5±0.5 mm.
