NEC dvd burnerAD-7170A 18x it is now possible for rewritable RW discs to be burned with the highest speed so far in the market, 8x for DVD +RW and 6x for DVD-RW respectively. The speed of writing with dual layers is now 8x for +R DL.
NEC dvd burner AD-7170 produced by Optiarc, a new joint venture of NEC and Sony. which adjusts the laser effect in real time so as to achieve optimal readability. The NEC dvd burnerAD-7170 is backwards compatible and writes on CD-R at a maximum speed of 48x.
The AD-7170A offers the fastest available DVD recording together with high speed CD recording and excellent read performance by utilising Sony NEC Optiarc's know how to develop and produce highly reliable optical storage devices.
With the AD-7170A the user does not need 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 Writer's the AD-7170A takes advantage
of "high resolution writing strategy", "Active Optimized Power Control" (Active OPC) and buffer under run error prevention technology developed by NEC. 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. These ensure 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.
