What is the difference between a DVD-ROM and a DVD-R copy?
DVD-ROM discs are produced by physically stamping encoded information onto a poly carbonate substrate. As with the CD-ROM, data is transferred to a master stamper and replicates are produced by pressing the discs from the master. DVD-R discs have a recordable dye that, when exposed to a concentrated laser beam, allows information to be encoded or burned into the disc.
