Multilevel-Enabled Double-Density Writable and Rewritable Digital Versatile Disc System.

Multilevel (ML) recording technology doubles the speed and capacity of standard digital versatile disc (DVD) writable and rewritable systems. Implemented with the addition of single chip or core to the standard drive architecture, ML technology doubles performance with no change to the optical mechanical unit. While custom media has been optimized for high speed ML recording, ML recording works well with standard writable and rewritable media.
