DX082D DVD+RW -
Taiwanese company has shown in the past that is capable of offering technologically
competent drives at very affordable prices. Although a little late, the company
the 4x DVD recording speed and followed the "plus" camp with the
8x DVD+RW writer.
The drive is built upon the Philips DVD+RW reference design, based on the
Nexperia PNX7850 chipset. The basic capabilities include 8x DVD+R, 4x DVD+RW,
32x CD-R and 24x US-RW recording. On the reading side the

a CD-RW/DVD+RW drive to automatically monitor the recording status and prevent
buffer under run from occurring.
Seamless Link allows the CD-RW drive to store the RecEnd address, the point
in the data to which the recording mechanism has progressed, and pause the
recording before a buffer under run occurs. When the buffer is again full,
a Seamless Link-enabled drive locates the RecEnd address and resumes the recording
process. The gap between the stop and restart point is closed, while managing
the recording process precisely and transparently-eliminating under run errors
while maintaining recording accuracy.
To ensure optimal writing quality over the entire disc at higher writing
speeds, Cyberdrive implements theWalking OPC algorithm, introduced by Philips.
WOPC directly measures and optimizes the actual writing quality during the
At certain intervals, the writing process will be briefly interrupted, the
writing quality directly evaluated and the writing power adjusted accordingly,
if required. The Cyberdrive DX082D uses a more dynamic implementation
based on the position on the disc and the temperature inside the drive.
In addition, Dynamic Calibration includes a tilt calibration feature.
The best reading and writing quality can be obtained if the angle between the
disc and the laser beam is 90 degrees. However, if the disc is warped, the
laser beam will no longer be correctly positioned which will cause a distortion
of the laser spot which will result in decreased writing quality if it is
The tilt calibration will reposition the Optical Pickup Unit (OPU) to maintain
a 90-degree angle between the laser beam and the disc surface at all times
ensuring an optimal spot shape, even on warped discs. The frequency of the
tilt calibration depends only on the position on the disc according to a non-linear
function. Near the end of the disc the risk for warping is higher so the frequency
of the tilt calibration will increase accordingly. As with WOPC, the writing
process will be briefly interrupted, the tilt measured and the OPU repositioned
Walking OPC and Tilt Calibration together form the Dynamic Calibration. Although
they act independently of each other, some effort is required to synchronize
the Tilt Calibrations with the disc position dependent component of Walking

The drive has an 8MB buffer size. Nero Info Tool confirms that
the CyberDrive supports reading of all the media formats except DVD-RAM.
The drive also supports RAW DAO 96 writing (CD). Mount
The CyberDrive DX082D drive, as most of the DVD drives, uses the RPC II region
control and allows the user to change the drive's region 5 times. For our
tests, we set
code to 2 (Europe).

taking a closer look at the drive itself we can see on the frond panel
the supported formats with their maximum speeds on the left. In the middle

and left of centre is the indicator light, which is
green while reading and
while writing. Right above the eject button located on the extreme lower right,
can be found the emergency eject
On the rear panel is the digital and analogue audio outputs
(SPDIF), the IDE connector
and the power input.
Removing the screws and opening the drive's cover voids the drive's warranty.
For reference reasons, we post the following pictures. The CyberDrive DX082D
is built on the Nexperia (Philips/BenQ) DVD+RW reference design. Click

Here can be seen the main chipset of the drive which is the
Nexperia PNX7850 from Philips, same with the one found in Philips latest DVD
The difference here is that Cyberdrive implemented all the capabilities provided
by the PNX7850, offering 32x CD-R and 24x CD-RW writing. (24x/10x for Philips
- Retail package
retail package includes the DX082D recorder, an installation guide, four mounting
screws, an audio cable and two blank media ( one DVD+R and one DVD+RW).
As for software there is a complete package from Ahead Nero including Vision
Express 2-SE, InCD 4, Nero Showtime etc.
The CyberDrive DX082D was connected to our test PC and was identified
as "CyberDrv DX082D" under
WinXP OS. All tests were done with firmware revision v100B.
In the following pages can be seen the test results and in addition a
comparison with three other DVD burners, the Philips DVR824P DVD+RW, the Optorite
dual DVD burners.
