LG GP60NS50 Slim Portable USB power DVD Rewriter - Silver

The M-DISC uses a patent rock-like recording surface instead of organic dye to etch your data onto a disc. The M-DISC has been tested and proven to outlast standard DVDs currently on the market.
Jamless play automatically prevents stop video playback in case of damaged disc, such as scratches or fingerprints by jumping through the erroneous data or damaged areas. As a disc is being read, Silent Play technology automatically controls the disc read speed for optimal noise reduction.
