Why do optical discs, such as CD, become magnetized?
First, it is thought that an iron ingredient contained in the printing ink of the label side of the disc is one of the causes of magnetizing discs. For example, iron oxide is used for red, yellow or brown ink, cobalt is used for blue or green ink and nickel is used for silver ink. These materials, iron, cobalt, nickel, are called ferromagnetic substances, and they are relatively easy to magnetize.
Second, problems are caused by the use of aluminum used for the recording side of CD. Currently, the JIS (Japanese Industrial Standard) states that the purity of the aluminum used must be 99.0%. The other 1% contains ferromagnetic substance such as iron, nickel and cobalt. Aluminum is a weak magnetic material, so it is easily influenced by magnetism.
CD players contain magnetic substances, when a disc is played, the rotation of the mechanism, magnet and motor generates a flux which quickly causes discs to become magnetized.
The same problem occurs in CD-R, DVD and MD. In particular MD uses an iron ingredient for the Magnet Catch, so the influence of magnetism is increased.In the worst cases, it is impossible to read signals.
Full effect for all optical DISCS
The RD-3 demonstrates the full effects not only with CD but with all optical discs. It is thought that electronic and information media will shift almost totally to optical discs so it is thought that the value in the use of RD-3 will increase greatly.
Here is a list of optical media (present and in future).
The effects on DVD and Laser Disc
The RD-3 has also remarkable effects on DVD and Laser Disc.
Picture quality: The RD-3 removes flicker noise leaving clearer and shaper image. A brighter color becomes brighter, a darker color becomes darker, so the contrast of the image becomes clear and more vivid. In addition, each single color becomes more extremely vivid, especially red. Moreover, the natural tone of the human skin is superb.
Sound quality:The RD-3 improves audio quality, and increases the level of surround separation and dynamics. You are able to listen to detailed sounds that you never heard before and the human voice is more realistic.
These effects on sound and picture quality are more and more evident with increasing quality of equipment used in the system. You can use the RD-3 for video cables, power cables and sound cables which further enhances the effects of demagnetizing.
After processing equipment, such as video cables, power cables and sound cables by RD-3, the performance of an AV system is greatly improved.
Not only do magnetized discs deteriorate the performance in a system, but associated equipment such as magnetized cables, connectors etc have a harmful influence on the sound quality and picture quality.
When an electric current flows through a cable, a magnetic field is generated.
IIf the current stops, the magnetic field should disappear. But the magnetic substances used for cable wires and connectors all contain impurities, so the electric current magnetizes these substances, and this has a harmful influence on the signals or the flow of the current.
It has been said that expensive cable or connectors are useless treasures not until the magnetization problem has been solved.
Other demagnetizers are less effective due to their shape or directions and cannot completely demagnetize cables or connectors. The RD III can be ore effectively used for a wider range of applications including metallic parts and speaker terminals.
When cable is short, you make cable round and process it. When cable is long, you process it dividing into several-time. Even if only the plug part is processed, it is effective.
