This demonstration works because the organic dyes in the center of the DVD+R or DVD-R have very little mechanical strength. Therefore, the interior of the disc cannot be substantially bonded together. This is one of the major reasons why delamination of a disc is a serious issue for failure and Data Loss. The M-DISC, however, has a robust, mechanically strong, inorganic material at the center of the disc that provides a very good foundation for bonding the disc together. There is no mechanically weak layer in the M-DISC, therefore the bonding is very strong, and the disc can withstand extreme abuse.
