CD-R is a "write once" technology that can be used in both CD-R
and CD-RW recorders and read by nearly any computer CD drive or
audio CD player.
In a CD-R the recording layer is made with organic dyes —
greenish cyanine dye, golden phthalocyanine dye, or silver-blue
The laser of your CD-R/CD-RW drive heats the dye to a temperature
of about 200° C, irreversibly melting a pitted pattern into the
recording layer. A plastic layer alongside the dye expands into
the newly available space creating a pit pattern similar to that
of a conventional CD. Your CD player reads this highly reflective
pattern for playback. Because the plastic layer melts into the dye
layer to set the pattern, CD-R discs cannot be re-recorded.
Unlike a stamped CD, CD-Rs are manufactured with a spiral groove
(like a phono disc) called the pregroove. It provides a
precise track for the writing laser to follow. A CD player depends
on following the recorded track of pits in order to track the
Phthalocyanine dye is superior to the Cyanine dye used in other CD
-R products for two reasons. One, Phthalocyanine dye is far more
stable than Cyanine. The information recorded on a Phthalocyanine
dye CD-R will last for over 100 years. Cyanine based products
might last 20 years. Secondly, Phthalocyanine dye is optimised for
use in higher speed writers.
This success is due to the accuracy with which laser light is able
to create "pits" in the Pthalocyanine surface. Pits etched into
Cyanine-based disks at high speed can be shallow or poorly
defined, resulting in a poorly written disc.
What Makes River Media CDRs the professionals best kept
River Media Diamond Phthalocyanine CDRs have outperformed Cyanine
in a series of tests when subjected to light, heat, and dampness.
These test results below highlight the difference.
River Media CDRs also have amongst the lowest C1 & C2 errors in
the industry. While a high level of C1, correctable errors, will
still probably be read by CD players and CD-Rom drives without too
much difficulty, C2 errors are more likely to be unresolvable and
result in the deadly CU, an uncorrectable error. A CU error will be
noticed by audio dropouts and and unwanted artefacts or read
failures on CD Roms.
A high level of errors will put more strain on error correction
circuitry and will force CD Players to interpolate samples to get
a reasonable value. This is what can result in noticeable audio
differences when played on high quality monitors or audiophile

- No colour bleeding - Our inkjet formulae utilises special
pigment molecules which prevent colour bleeding
- Brilliant White - No off-white or cream finish, when we say
white we mean it!
- Thermal Surfaces Optimised for specific printers - River Media
offer dedicated discs for both full colour and mono printers
We're so confident in the quality of our media that should you not
be entirely satisfied we'll offer a full refund - no quibble.
