Nec presents the 1st generation of 18x dvd recording drive that supports all types of dvd and cd media currently available - in reading and writing. In addition to 18x1 write speed for dvd-r and media, 6x2 write or rewrite with dvd-rw and 8x2 media, 12x write on corresponding dvd-ram media, the drive is capable to write up to 8.5Gb with maximal 8x3 speed to dvd media and dual layer dvd-r dl3. Besides 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 comprise in total 11 optical storage. The ad-7170a is available in black, beige, silver. This is an oem product. The ad-7170a offers the fastest available dvd recording together with high speed cd recording and excellent read performance by utilising sony nec optiarcs 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 necs predecessor dvd writers 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.
