LG - 8x External Double-Layer DVD±RW/CD-RW SuperMulti Blade Drive - Silver

"Double-Layer DVD±RW/CD-RW" is referring to the type of DVDs and CDs. Those are discs that provide twice the storage capacity of a standard DVD or CD recordable disc. The discs employ two recordable dye layers with each being capable of storing nearly the 4.7 GB capacity of a single layer disc, almost doubling the total disc capacity to 8.5 GB. The LG 8x Portable DVD Rewriter with M-DISC™ SuperMulti Blade Drive, Model # AP70NS50 can read such discs and the discs can only be created using DVD+R DL and Super Multi drives...^IFV

The LG 8x Portable DVD Rewriter with M-DISC™, Model # AP70NS50 can retrieve and/or store data on optical discs like CDs, or DVDs, any of which hold much more information than previously available portable media options like the floppy disk. There’s no difference between copying files, photos, MP3s or video files from a CD or DVD to your hard drive than from any other kind of storage or burning photos to a CD or DVD disc. If you have those photos saved on your computer, just insert a blank CD or DVD into the drive and click on My Computer and then click on the DVD drive to open a folder, open the folder in which you have saved the photos. Click on the photo files to highlight them and drag them over to the CD folder. Click on the "burn to disc" option and a burn wizard will appear to guide you through the CD burning process. When the wizard finishes, the files will be burned to the disc...^IFV
