M-Disk Information: · As opposed to light-sensitive organic dye use in standard CD, DVD, and less expensive BD (Blu-ray) discs, M-DISC is more stable, less corruptible, and is said to last ten times longer (up to a 1000 years) due to its resilient optical disc format that uses a rock-like non-volatile data layer. The technology is specifically designed to "etch" permanent data onto M-DISC media from an M-DISC writer or burner. M-DISC claims their discs are designed to protect your photo, video, music, and document data from degradation and loss for centuries whereas hard drives, flash drives, and other writable media can lose data. Information on making copies: · Just place your master on the very top drive. · Insert your desired number of disc (if you have more than one burner). · Select 'Copy' on the LCD. Then press 'ENT' These formats can be copied: · The DVD Duplicator can copy from CD-R to CD-R, CD+R to CD+R, DVD-R to DVD-R, DVD+R to DVD+R, and up to DL to DL. One of the many settings on the duplicator is called “Compare”. This will check to see if all the copies are accurate. The duplicator will check the copied disc and compare it with the master disc bit by bit to ensure that the copy is 100% accurate.Included: Pro Duplicator, Power Cable, USB Cable, Original Operators Manual.
