IMPORTANT SAFETY NOTES
<< The machine may not be operated by more
than one person at any given time!
The machine was designed for safe operation
by “one person only”.
<< During the destruction process no other
work may be performed on the machine
(for example cleaning, etc.)!
<< The machine is not a toy, and is not suitable
for use by children!
The overall technical safety concept of this
machine does not provide for any guarantee
regarding hazard-free operation by children.
<< Do not attempt to handle the disc during
a destruction phase! Danger of injury!
<< In case of danger switch the machine off
with the mains switch, or with the emer-
gency switch, or unplug the machine!
<< Always unplug the machine from the mains
power supply before opening the machine!
Repairs may only be performed by trained
personnel!

CD Construction
A CD-ROM is made up of multiple layers. It con-
sists of one 1.2mm polycarbonate disc. Data re-
sides in the “information layer” of pits and lands.
Data is a sequence of 9 unique spaces of lands
and 9 unique sizes of pits. Data is imbedded in
the polycarbonate.
Data is contained in the polycarbonate surface
of a commercially produced CD-ROM disc to a
depth of @ 100 nanometers (0.001mm). To de-
stroy the data 100% in a commercially produced
disc, the grinding process needs to just penetrate
the polycarbonate layer. Data is contained in the
chemical layer on a recordable disc, between
the polycarbonate layer and the protective sur-
facing on the discs. To destroy 100% of the data
contained in a CD-R or CD-RW disc, the che-
mical surfacing above the polycarbonate needs
to be removed. The grinding process of the unit
provides complete 100% destruction of the in-
formation layer of both commercially produced
CD-ROM discs, and CD recordable discs.
DVD Construction Blu-ray Construction
A DVD-ROM consists of two 0.6mm polycarbo-
nate discs bonded together. Like the CD-ROM,
data on a DVD-ROM resides in the “information
layer” of pits and lands. Data is a sequence of
9 unique spaces of lands and 9 unique sizes of
pits. Data is imbedded in the polycarbonate.
Data on a DVD-ROM is contained in the center
of an assembled disc. To destroy the data 100%
in a commercially produced disc, the two poly-
carbonate halves must be split to expose the
information layer. Once split, the same grinding
process as described for a CD-ROM applies.
A Blu-ray disc, the nal standard format which
won over international acceptance from the HD-
DVD format manufactured by Toshiba, is similar
in construction to a CD-ROM. The data layer re-
sides near the surface of the disc. The Blu-ray
disc is 1.2mm thick, like a CD-ROM and a DVD,
but unlike the standard DVD, the Blu-ray consist
of one 1.1mm layer, then the data layer, and a
very thin 0.1mm protective layer. To destroy the
digital data content, the unit does not need to
rst split the disc but simply to grind down into
the Blu-ray disc slightly below the 0.1mm protec-
tive layer. This new standard for DVD will be the
dominant form factor within the next 1-2 years
while standard DVDs will become less and less
prevalent in the storage industry.
Like the CD-ROM, data on a Blu-ray disc resides
in the “information layer” of pits and lands. Data
is a sequence of 9 unique spaces of lands and
9 unique sizes of pits. Data is imbedded in the
polycarbonate.
Data is contained in the polycarbonate surface
of a commercially produced Blu-ray disc to a
depth of 0.1mm. To destroy the data 100% in a
commercially produced disc, the grinding pro-
cess needs to just penetrate the polycarbonate
layer. The unit accomplishes this.

Sub-layers Destruction Process
The intimus 005S technology, in combination
with the DVD splitter as applicable, physically re-
moves the information layer from the CD-ROM,
DVD ROM, and Blu-ray disc permanently and
safely while keeping the polycarbonate material
intact.
The intimus 005S design specication requires
the data layer of optical drives to be ground to
250 microns - eliminating forensic recovery of
data by any known means.
