marketing to manufacturers of optical disc drives (DVD and CD drives) for
integration into products such as PCs. The company will operate on a global

The new company will pool the best in optical disc drive technology (e.g. NEC's
strengths in LSIs and Sony's expertise in optical pickups) to deliver high
quality and reliable products to consumer electronics and PC makers on a timely
basis.

Sony's President and Electronics CEO, Ryoji Chubachi commented:

Optical disc drives are key components for a broad range of devices and we are
strategically focusing our development resources in this sector. By teaming with
NEC which has excellent technology in areas such as DVD drives, I believe we can
work effectively to enhance our product lineup and quality on a global scale.

NEC's President Akinobu Kanasugi, commented:

The market for high value-added drives to be integrated into PCs and consumer

allow us to realize the aim of becoming the top vendor in this sector.
