NEC DVD Burner
DVD writers are becoming more common nowadays for households because the average price of the drive keeps on dropping day-by-day. Two competing, incompatible formats—DVD+R and DVD-R (and their corresponding rewritable formats DVD+RW and DVD-RW)--are trying to become the default DVD format which is becoming more and more popular.
NEC presents the first generation of 18x DVD recording drive that supports all types of DVD and CD media, which are available at present - in reading and writing. In addition to 18x write speed for DVD-R and DVD+R media, 6x write or rewrite with DVD-RW and 8x DVD+RW media, 12x write on corresponding DVD-RAM media, the drive is competent to write up to 8.5GB with maximal 8x speed to DVD+R media and dual layer DVD-R DL. Apart from DVD recording, the drive writes CD-R media with up to 48x speed as well as Ultra-Speed CD-RW discs up to 32x. Together with the read speed of 16x for DVD-ROM and 48x for CD-ROM it comprises in total 11 optical storage.
The AD-7170A of NEC offers the fastest available DVD recording together with high speed CD recording and excellent read performance by utilizing Sony NEC Optiarc's know how to develop and produce highly reliable optical storage devices.
With the AD-7170A the user does not have to decide between DVD formats he has the freedom to choose the DVD R, DVD rewriteable or DVD R two layer media of his choice without a compromise in performance or storage capacity: 1 hour DVD Video can be recorded in just 5 minutes.
As with NEC's predecessor DVD Writers the AD-7170A takes advantage of high-resolution writing strategy, Active Optimized Power Control and buffer under run error prevention technology developed by NEC. The high resolution writing strategy uses advanced laser modulation to improve the accuracy of the written data. Active OPC dynamically check writing power and reflection of the media in use, calculating the optimum laser power and adjusting it in real-time. These make certain that not only the media type itself is written in the optimum way but any local anomalies on the used media can be handled in the best possible way by NEC technology
