Question: What is "dual layer?"
[Email To a Friend] |
| Answer: Dual layer, when referring to blank recordable media, is a relatively new media technology that has two 4.37GB blank recordable layers suspended on the disk to form a storage capacity of approximately 8.5GB. One layer is semi-transparent, which allows the optic laser to access the second opaque layer by refocusing the laser to a different length. This is also referred to as a "DVD-9" recordable blank or a DVD+R DL. (NOTE: This DL format is currently ONLY available in +R.) Dual layer, when referring to optical drives, refers to drives that will burn this new media format. (NOTE: As of this writing, these drives are fairly new in the marketplace. Not all drives are dual layer burning drives. Please check with your drive manufacturer if you are unsure if your drive supports dual layer burning.)
