Below, you will locate the maximum common terminology that
relates to CD duplication. Even if you are new to
duplication, the phrases beneath may also help you study more.
BLER
Block Error Rate. This is the raw virtual error fee
before any sort of errors correction.
CD
This the Compact Disc, a digital medium this is fashioned
of a 12cm polycarbonate substrate, a reflective
metalized layer, and a shielding lacquer coating.
CD-R
Compact Disc-Recordable. The term CD-R is used to
describe the era of recordable CD at the side of
the system, software program, and media which can be used to
make the recordable disks.
Data layer
With CD-R media, this is the organic dye that is
sandwiched between the polycarbonate substrate and
the metalized reflective layer of the media. CD-R
disks have no facts on them at all till the
are recorded.
Injection Molding
This is a producing approach in which the molten
fabric is forced right into a mold, normally beneath
high stress, then cooled so that the fabric
will take at the form of a replicate photograph in the
mould.
Media or blanks
CD-R media are the disks which might be used to file
virtual statistics using a special recorder and
premastering software with a computer. These discs
are made from a polycarbonate substrate, a layer of
natural dye, a metalized reflective layer, and a
coating of lacquer for protection.
Organic dye
The records layer of CD-R media is crafted from a dye
that is melted in the course of the manner of recording.
Where the dye is melted, becomes opaque or
refractive, scattering the studying laser so that
it isn’t always reflected again into the analyzing sensors.
Reflective layer
This is the metallic later that sits on top of the
dye that reflects the laser beam lower back to the
reading assembly. This is normally 24k gold in
CD-R disks, although it could be silver as well.
