Double-Layer DVD: Lite-On, LG and BenQ

LG GSA-4120B

Rightly named SuperMulti Drive, LG's GSA-4120B is compatible with all the existing DVD formats, both for playing and burning. Its top speed is 12x in DVD+R mode. But it is also capable of burning DVD-Rs in 8x, DVD-RWs and DVD+RWs on 4x, and DVD-RAMs in 5x. This last format is not often found in Europe and is generally confined to professional use. So it's a real multipurpose burner that also has double-layer technology (DVD+R DL).


LG developed its GSA-4120B LG through the Joint Venture HL Data Storage (Hitachi-LG Data Storage) using a processor (LSI) that combines the two chips used previously in its other burners.
