The DaTABANK quality assurance tool from DaTARIUS was used
to analyze the DVD media in this test. These systems measure recorded
and unrecorded DVD discs and include a Sony Reference Drive, which correlates
with the Pulstec SDP-1000 optical drive, capable of measuring at speeds of up
error (POF) and jitter, are measured using this system.
The DaTABANK was developed with the highest demands on measurement
flexibility of hardware and software. The system’s highly modular design,
allows easy upgrades of both software and hardware.
The DaTABANK has been an industry standard media testing system, installed
in the majority of optical media production plants. The system offers full
control of the production process for all DVD, BD and HD DVD formats, including
dual-layer recordable discs.
One of the main advantages offered by DaTARIUS for the DaTABANK system, is
its easy to use user interface software, called DaTAVIEW. The software is
used to operate the
system, user administration, hardware monitoring, remote control and maintenance,
as well as and view and
results (result display & export & statistical analysis. trend charts).
DaTARIUS has developed the DaTAVIEW software, having in mind that a system
should always present information in a user-friendly way.
The DaTAVIEW software is responsible for the generation of accurate
charts illustrating the parameters specified for each quality measurement,
filters, organizes and illustrates the data imported by the measuring system,
according to the operators needs. Critical quality parameters can be isolated
from the full list of measurements and be separately presented, offering easy
yet stringent control
over the production process. All the measurement/graph
parameters, can be easily set with a few mouse clicks, in a full Windows-based
environment menu interface. The operator is able to configure signals, their
Below is a FE (Focus Error) sample graph for a DVD disc, as produced
by the DaTAVIEW software:
A very interesting and useful tool of the DaTAVIEW software is QualityWeb.
It is a dynamic viewing feature, that offers a clear and complete visual presentation
of disc quality. The operator is able to configure the multiple parameters included
in the display, and thus have an idea of the quality of a disc at a glance. In our example,
both JC (jitter) and POF values are not graphically included within the inner
area of the the red polygon and so show up as exceeding the quality limits
set by the operator:
In addition, DaTAVIEW presents the disc surface diagram, which displays
from one signal (quality parameter), in a unique visual representation:

The results can be printed, saved as an archive for future reference, or exported
to one of several popular formats including .csv and .xls.

In our tests, we used the DaTAVIEW software to monitor JC, PI Sum8 and
POF measurements. Measurements were taken at nine specific points on the disc,
at a reference speed of 1x, starting from the inner tracks and progressing towards the outer, in an effort to cover
the whole disc's area.
The results were exported
to Microsoft Excel where
then generated. Keeping in mind that the data presented in the graphs is taken at
discrete points, the graphs most likely indicate the trend of how quality changes
from the inner to the outer area of a recorded disc.
The test results are presented in the ensuing pages.
