World's First Super Multi Drive With 5x DVD-RAM (May 2004)

TOKYO--(BUSINESS WIRE)--May 18, 2004--Hitachi-LG Data Storage, Inc. (CEO: Kazuya Hori) has developed GSA-4120B, the world's first Super Multi drive with 5x DVD-RAM. The Super Multi drive supports not only DVD-RAM but all writable DVD's(1). The shipment is scheduled to start in June, 2004.

GSA-4120B is the successor to the conventional Super Multi drive, GSA-4082B. This is the first time in the world that DVD-RAM can be written at 5x. What's more, GSA-4120B is capable of writing +R at industry's top level speed 12x, and is also compatible with +R double layer discs. It 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.

    (1) all writable DVD's:
        All writable DVD formats standardized as of April 30; writable
        DVD formats (DVD-RAM/R/RW) and +R/RW formats.

    --  OUTLINE OF GSA-4120B
   Product Name            Model          Shipment   Projected  Sales
                                          Schedule    Volume     Type
PC built-in type   Super Multi GSA-4120B    From    700K units   OEM
DVD writable drive (ATAPI-Interface)     June, 2004   / month
GSA-4120B is a built-in type Super Multi drive that can read/write all types of DVDs and CDs. Not only does it write DVD-RAM at the world's fastest speed 5x, it also write +R at 12x, DVD-R at 8x, DVD-RW and +RW at 4x, all of which are the industry's highest speed. Unquestionably, this drive has the most up-to-date functions such as CPRM which is becoming a hot topic in Japan due to start of digital TV broadcasting, multi-boarder and the quick format used with DVD-R/RW, and the multi-session and the background format used with +R/RW.

By increasing the speed of writing DVDs, this drive succeeded in shortening the time used for making DVDs, and in speeding up data backup processes. Moreover, by supporting 5 types of writable DVD formats, it is also the best choice for users who use DVD recorders which have grown popular nowadays. Further, this drive succeeded in increasing the speed of writing CD-R substantially, with the write speed 40x at max.

GSA-4120B 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.

It inherits from its predecessor, the conventional technologies for stable writing such as the built-in LD driver with highly reliable write strategy and the buffer-under-run prevention function. In addition, as with its predecessor, it boasts its compact design which is convenient for all PCs.

The key technologies developed in order to realize this product are as follows.

-- Compact and high power optical pick up for 12x write

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

-- 1 chip LSI (DSP) for 5x DVD-RAM and 12x +R

Not only accomplished speeding up the high function LSI (DSP) of the conventional product which process all formats (DVD-RAM/R/RW, +R/RW, CD-R/RW, DVD-ROM and CD-ROM), but also succeeded in devising a 1 chip system instead of the conventional 3 chip system (DSP, MPU, SDRAM). This 1 chip LSI contributes to reduction of current consumption, high reliability and compact design.

-- High-precision LD power learning control for 12x write

By adopting the newly developed high precision LD power control learning method that applied DVD-RAM's LD power learning method, the recording quality at 12x is secured.

-- Stable and high speed disc rotation mechanism

Stable operation is also secured at high speed disc rotation to realize high quality write/read.
