Hitachi-LG announces 8x Super Multi Drive


Hitachi-LG Data Storage has developed the world's first 8x high-speed writable DVD drive, GSA-4082B, which supports all writable DVDs. The shipment is scheduled to start in February 2004.

GSA-4082B is the successor to the conventional Super Multi drive, GSA-4040B and what's more, is capable of writing DVD-R/+R at 8x and writing DVD-RW/+RW at 4x. Without saying, this drive inherits the ability to write DVD-RAM at 3x. It also reads and writes CD-R and CD-RW, and reads DVD-ROM and CD-ROM as well, which makes this drive compatible with totally 9 types of discs.

GSA-4082B was developed in collaboration with related companies, by gathering all of the companies' latest technologies for overall development from key components to the product itself. The key technologies developed in order to realize this product are as follows. In addition, it inherits from its predecessor other technologies for stable writing, such as the LD driver with highly reliable write strategy built-in and buffer under-run prevention function.

Compact and high power optical pick up for 8x write

A high power laser allowing high-speed recording is embedded. Its unique heat radiation structure acquires high speed and stabilization, realizing high performance.

1 chip LSI (DSP) for 8x write

Accomplished speeding up the already high-speed high function LSI (DSP) developed for the conventional products that process all formats (DVD-RAM/R/RW, DVD+R/RW, DVD-ROM, CD-R/RW, CD-ROM).

High-precision LD power learning control for 8x write

By adopting the newly developed high-precision LD power control learning method which applied DVD-RAM's LD power learning method, the quality of recording at 8x is secured.
