Lite-On developed the Smart Erase technique to give users a reliable way of erasing the data on CDs and DVDs without damaging the disk. This technique is compatible with all CD-R and DVD-R disks, not only their rewritable counterparts. Smart Erase overwrites the data contained on the disk with random characters much like the tools that can erase files or the free space of a hard drive so that the data is not recoverable afterward. Nero 7 Essentials which ships with the retail versions of each DVD writer will have that feature build in which can be used in combination with one of the announced Lite-On DVD writers. The new technique supports two modes: Quick Erase will only erase data in the lead-in track and the first track of the CD / DVD while Full Erase will erase the full disk.
