NEC ND-2500A MultiSpin 8X DVD Writer available by end of December


NEC introduces the first dual 8x DVD recording drive, capable to write at 8x speed DVD-R and DVD+R media as well as 4x speed writing or rewriting with DVD-RW and DVD+RW media.

Besides DVD recording, the drive writes CD-R media with 32x speed as well as Ultra-Speed CD-RW discs at 16x. The read speed of 12x for DVD-ROM and 40x for CD-ROM in combination with the access time of 140 ms for DVD and 120ms for CD comprise the most important 8 optical storage functions in 1 drive – the ideal all in one optical device.

The ND-2500A takes advantage of NEC’s “high resolution writing strategy” and of an improved version of NEC’s “Active Optimized Power Control” (Active OPC). The “high resolution writing strategy”, uses advanced laser modulation to enhance the accuracy of the written data. Active OPC dynamically monitors writing power and reflection of the media in use, calculating the optimum laser power and adjusting it in real-time. Besides, NEC implemented its own developed buffer under run error prevention technology.
