LG GSA-4081B Multi DVD Recorder -
Most people know of LG as a consumer electronics manufacturer. It is among the
top Electronics manufacturers in Korea, and one of the largest worldwide. Lately,
LG has also managed to become a leader in the optical storage industry, offering
fast and affordable CD/DVD recorders, and is among the few companies supporting
the DVD Multi Recording standard.
The first "Super-Multi" drive, the GMA-4020B, was announced last
year. The drive was born from the joint venture between LG and Hitachi. Although
the company initially supported only the DVD-R/-RW and DVD-RAM formats, the

added DVD+R/+R writing while also boasting of recording speeds of 4x DVD±R,
2.4x DVD+RW, 2x DVD-RW and 3x DVD-RAM.
LG upgraded the specifications of its processor drive (GSA-4040B) offering
8x DVD+R and 4x DVD+RW writing. Of course, the drive supports 3x DVD-RAM and
4x DVD-R writing.
