There is a difference in CD-ROMs. For only a little more, Medical Grade CD-ROMs will protect your Patient's vital study. You can buy CD-ROMs on spindles for under a dollar. For a dollar and change more, you can write your Patient's Medical Images on a Medical Grade CD-ROM. Complete with your own LOGO. A lot of insurance for little money.
One of our Hospital directors was asked " why do you pay more for CD-ROMs when you can buy them on a spindle at Staples. The answer " If the case is lost because of CD-ROM media problems and we re-cath and something goes wrong.... well, how do you think it would look ". A very good point.
Gold-on-Gold Blank Media
Mitsui created and patented the phthalocyanine (thal-o-sy-a-nene) dye used in their high quality gold-on-gold CD-R recording media. Phthalocyanine is considered superior to Cyanine dye because it lasts longer and works better at speeds up to 8X. Mitsui has developed an additional layer of protection called the Data Shield Surface (DSS) which is applied on top of the lacquer layer. Extra coating provides an extra measure of protection against light, heat, moisture and rough handling. Mitsui's longevity complies with the Orange Book Standard for Block Error Rate (BLER) set by the industry for CD-Recordable media.Mitsui disks have the longest warranty on the market - each disk is warranted for life.
Medical Dynamics can have your Logo on Mitsui CDs in a matter of days. Call or Email for more information.

| How
are CD-R discs different from CD-ROM discs

CD-R discs are quite different from conventional CD-ROM discs. CD-ROM discs are mass produced using specialized equipment and are projected to last for about 20 years. CD-R discs can be written at your desktop using an inexpensive CD recorder and, in the case of Mitsui Gold media, are projected to last for well over 100 years. The layering structure of a CD-ROM is shown below:
The lacquer coating is applied as a protectant. In comparison, CD-R discs are more sophisticated and robustly constructed. The information on a Mitsui Gold disc is projected to last for well over 100 years. The layering structure of a Mittsui Gold CD-R is diagrammed below:
As in a conventional CD-ROM, polycarbonate is used as the foundation. However, CD-R uses a special dye which is etched by laser to create the pits and lands. This dye will be covered in the next section. A layer of lacquer is then applied, followed by Mitsui's patented Data Shield Surface which provides additional protection against environmental hazards and rough handling. |
The dye formulation used in a CD-R is perhaps the
most critical factor in the disc's performance. Mitsui Gold discs utilize
a patented Phthalocyanine dye (thal-o-sy-a-nene) which offers substantial
performance advantages. You can recognize a Mitsui disc by turning it over
and looking at the color of the writable surface. A Phthalocyannine disc
is gold colored with a slight greenish tint. Other manufacturer's discs
come in a variety of shades ranging from blue-green. Both varieties of
discs will be gold colored on the top, or non-writable surface.
Mitsui Gold Phthalocyanine-based discs offer substantial performance
advantages over other discs in two key areas; longevity and compatibility
with high speed CD recorders.
Longevity on the order of 100 or more years is derived from the inherent
stability of Phthalocyanine dye. Phthalocyanine-based discs can withstand
environmental conditions that could render other discs useless. This is
because Phthalocyanine resists ambient heat, light, and humidity better
than other dye formulations even after the disc has been written to.
Phthalocyaine is also more compatible with high speed writers. Mitsui was
the first manufacturer to be certified by Yamaha to work with their 4X
writers and is also certified for use with the Kodak 6X system. This
accuracy is due to the precision with which laser light is able to create
pits in the Phthalocyanine dye.
