A Digital Versatile Disc (DVD) is just like a CD disc and is used to store data. Compared to a usual CD, a DVD can save more data. Sony Magneto Optical Media and Sony Magneto-Optical Media - 5.20 GB are some of the best DVD media you can have these days. The performance stability is ensured by the company’s substrate molding technology and high precision stamper. Other DVD media devices such as IBM Magneto-Optical Media - Rewritable – 5.25 - 1.3GB are highly recommended for long-term data archiving. Each of these devices uses its own mechanical components and rough cartridge architecture to accomplish durability of a minimum of 100,000 unload/ load cycles per side.
