SUCCEEDS TO MASTER
For the third decade now Dr. Schenk offers an extensive range of products for
automated quality assurance and production process monitoring. Having been
the first, and for a long time the only supplier for optical media inspection and
process control, we are proud of the experience and competence we have
gained during this time. Mixing this tradition and strength with constant
technological advance we are ready to inspect Blu-ray media discs and are
already well prepared for the next OD generation such as holographic discs.

Inspection by Dr. Schenk – history and future
For the third decade now Dr. Schenk offers an
extensive range of products for automated quality
assurance and production process monitoring.
Having been the first, and for a long time the only
supplier for optical media inspection and process
control, we are proud of the experience and
competence we have gained during this time.
While we continuously apply new optical
technologies to our inspection products we
develop systems for industries besides optical
media. The past 12 months for example have
proven that quality assurance and process control
for thin film solar modules is a rapidly growing
market in which we have successfully become a
leading inspection equipment supplier. With the
expected immense growth in this area, we have
now enlarged our engineering, production and
sales resources and founded a solar business
division. At the same time, Dr. Schenk has not
slowed down its efforts in the optical media sector
and is setting precedence in the new format
generations by anticipating their needs for
surface inspection.
Technological evolution, organizational
stability & growth
Known as the inspection pioneer for the optical
media industry, Dr. Schenk today continues to
set standards for the high definition formats. Bluray
disc replicators and manufacturers rely on
the quality assurance and process control
systems that have ”precision in focus“.
The perfect synergy between technical
innovation, experience in optical design, close
relations and collaboration with major developers
of the new media format as well as a solid and
growing organization builds the basis for
Dr. Schenk‘s Blu-ray competence and business
success. To benefit our business partners, the
Dr. Schenk organization fosters close
communication and cooperation between its
global offices. Our long term customers especially
appreciate the fact that Dr. Schenk boasts a high
satisfaction. A low employee turn over rate
additionally benefits our customers in that their
direct contact person is highly familiar with a
product and its specific adaptations which speeds
up the response to service requests enormously.
Business partner of choice
Dr. Schenk’s core competences in optical
technology and our understanding of the
inspection needs within the media industry is
considered unmatched. Our existing customers
repeatedly decide for Dr. Schenk as their
preferred supplier and partner out of satisfaction
with our products and after-sales service we also
successfully win new customers due to our
products’ competitive advantages.
Preparing now for Generation IV
Dr. Schenk’s long tradition and experience in the
Optical Disc area as well as the close cooperation
with manufacturers and process integrators let us
anticipate new technological developments and
trends at a very early stage. These developments
and trends are then transformed into practicable
and highly reliable products and features. This
long term view and early efforts enable us to offer
our customers stable and proven systems for
inspection and process control as soon as a new
format is emerging. With the Blu-ray disc market
starting to take shape, we expect that in 2008 our
first developments and R&D resources in the
GEN IV will soon will pay off. Also, for
holographic media disc we have made early
contacts with our business partners and
customers to develop inspection and process
control systems for this new technology.

READY FOR BLU-RAY INSPECTION – THE CHALLENGES OF THE
NEW MEDIA FORMAT
The new disc format Blu-ray discs (BD) is based
on blue laser technology, enabling a substantial
increase in recording density. The production of
Blu-ray discs involves spin coating of cover and
space layer. These coating processes are still new
and challenging and very vulnerable to layer
thickness variations on the one side and new
types of defects on the other. Both could cause
the pick-up head to loose its focus or track.
How do the ISM.blue+ and the PROmeteus
MT-200.blue address these challenges?
The cover layer – unique to BD discs - and the
space layer of DL discs have to be analyzed with
highest precision. Our in-line scanners measure
the layer thickness on 4 or 8 radii and deliver a
radial thickness profile for production process
control.
However, even more critical are local thickness
variations and deformations that can occur
between the measured radii, like e.g. burst
bubbles, can only be reliably detected if 100
percent of the disc area is checked. In contrast
to competitors scanners that now test on 20-30
radii to cover a slightly bigger disc area,
Dr. Schenk has decided against a simple
increase of measured radii. For DVDs and lately
for BD discs a radial thickness profile on 4 radii
has been proven sufficient for process control.
Our scanners perform a thickness analysis with
an additional inspection channel. The parallel
measurement via our Enhanced ACC-Channel
delivers a coating topography on 2048 radii for
improved process and quality control.

The second big challenge in BD replication
process are the new local defect classes that
can occur in cover and space layer during the
spin-coating process and – for dual layer discs –
during the embossing of the information layer.
Thomas Ruck, Product Manager Blu-ray
Inspection, and his team have classified these
new defect types and developed innovative ways
for a reliable replication process analysis.
Instead of just an upgrade of a standard DVD
scanner, a completely new optical channel has
been developed for the ISM.blue+ unit.
Inspection on two complementary channels
enables correct discrimination between standard
contrast defects and various deflecting defects.
“The accurate classification and evaluation of
defects will lead to higher yields as we now can
minimize incorrect disc rejection” says Thomas
Ruck.

A SERVICE PARTNER
YOU CAN RELY ON
Dr. Schenk’s main objective is to offer a “solution”
for our customers’ inspection and process control
needs. Therefore we are not satisfied with only
selling a system and getting it installed into the
production line. Service offices in Europe, the
USA, China, Hong Kong, Korea, Taiwan and
Japan guarantee a fast response to support and
training requests that are regional and close to
the customer.
Customer Specific Product Training
Dr. Schenk has taught nearly 1000 participants
how to operate, calibrate and maintain our
inspection- and measurement systems.
Dr. Schenk Training Center
To ensure operators and service engineers
become quickly familiar with Dr. Schenk
inspection and measurement systems, a variety
of customer trainings are offered. Trainings are
held in-house or at customer sites worldwide.
For a detailed course description please visit the
Support-Chapter on www.drschenk.com. Contact
your local service hotline to arrange a training
adapted to the specific needs of your personnel.

Service & Support team at the
Dr. Schenk Headquarters near Munich
Every second counts
Currently Dr. Schenk supports more than 10,000
inspection systems around the globe. Among
these are 7,500 ISM scanners for optical media
production. A highly qualified global service team
is available even after the warrantee has expired.
Holger Schimanek, leader of the Munich
customer service center explains what our
customers can expect and appreciate as
competitive advantage in the industry.
“Dr. Schenk scanners and systems are known for
their durability and system stability. Requests for
support and service typically occur after years of
operation. Here our service team offers a 3 level
service for a fast and reliable help at a minimum
of costs.”
The entire service team is highly trained
with each product and their customer specific
adaptations. As time is very costly for every
second an inspection system is down, a fast
resolution is critical. We are able to respond to 90
percent of the requests via email and the
worldwide telephone hotline. Our colleagues from
the service department identify if a certain system
part needs to be exchanged and provide
installation instructions to the maintenance
engineers including an fast order and delivery
process of replacement parts. We also are proud
of our global service network which provide fast
on-site service when needed for system
adjustments for parts installation.
