Use disc images for your CD and DVD backup. Replace your physical discs to avoid wear and tear on your optical drive, and to avoid disc problems resulted from heat, scratch, and dirt. Enjoy reading speed up to 200 times faster than a physical disc, allowing your application and games to start and run faster.

CD-R/RW, and DVD+-R/RW have a life span of two to five years. Optical discs commonly used for burning have a recording surface consisting of a layer of dye that can be modified by heat to store data. The degradation process can result in the data "shifting" on the surface and thus becoming unreadable to the laser beam.

To avoid burning your CD's every few years, copy the CD and DVD's to ISO or BIN/CUE disc images to your hard drive.
