CD-R:

disc, 650MB data,Write Once.
CD-R: 80 min, CD-R

CD-RW: 74 min, Rewritable
media disc, 650 MB data.
CD-Rw: disc
allows you to erase data stored on it and re-use the same
piece of medium for new data.
Disc manufacturers correctly warn that 80
min. discs may not be recordable in all drives or with
all recording software, and that recorded discs may not
be readable in all drives. "Business Card" or other irregular
shapes may result in unpredictable interchange. Discs
that work in some drives can fail in others. Old CD-ROM's
and audio CD-Players will NOT be able to read CD-RW discs,
simply because they weren't designed to handle the low
reflectance a CD-RW disc has.
There are a lot of these low budget CD-R's
on sale everywhere but no one can really tell what the
quality of these CD-R's is and will be the impact of aging
is on the CD-R's. The quality of CD-R's is directly related
with the time the CD-R's will last without losing the
information on them. The second important issue is that
the CD-R can be used on any kind of CD-Reader without
any problems. Dye Type Longevity cyanine (often resulting
in blue/green CD-R discs) about 70 years pthalocyanine
(often resulting in yellow/silver CD-R discs) about 100-150
years.

The
different colors:
which show up when you look at the bottom of
the CD-R are a combination of the reflection layer and
the dye color a Blue dye and a Gold reflection layer will
generate a Green colored bottom.
The gold-colored CD-R uses the PhthaloCyanine
pigment and a gold reflection layer. As the pigment is
transparent, the golden reflection layer shines through
the bottom side giving the `golden' look. Compared to
the other colored media, the reflection contrast of the
golden medium is the highest and the durability of such
CD-R's is said to be over 100 years.
the golden medium's reflective property is the highest
The green CD-R, the cheapest of the three,
uses the Cyanine pigment. By itself, the pigment is blue
in color, but together with the gold reflective layer,
the bottom appears green. However, cyanine's ability to
maintain reflectivity is poor giving it a life span of
about 10 years. It also delivers
the weakest reflection contrasts and thus can cause read
errors when run on old CD-ROM drives. Lately cyanine formula
has been altered which results in a much higher life span
(20 to 50 years).
The gold reflection layer has also been
replaced by a silver reflection layer this make the color
of the bottom appear blue. The blue media is made of Azo
pigments. Like cyanine, it is blue in color but unlike
the green CD-R it uses a silver reflection layer which
gives the blue color. Manufacturers claim blue CD-R's
are as durable as golden ones.
