When a disc (cd, dvd etc) has become magnetized, you can never obtain the maximum available sound and image quality from the recording
Why do optical discs, such as CD DVD etc, 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.
It is impossible to demagnetize your discs completely by other demagnetizers such as Head eraser or Bulk eraser. However, some of these machines may actually induce magnetism.
Head eraser or Bulk eraser can't demagnetize CD, MD or Cables completely because of their shapes or directions. In fact, they magnetize discs in many cases.
From information that we have studied it is easy to see that before a demagnetizing process has been carried out, it is impossible to obtain
the highest quality information from a CD or DVD (audio and video signal
quality)Even when you use expensive electronics (CD / DVD players etc), it is
impossible to reproduce accurate information that is sound quality for CD,
picture quality for DVD, unless you demagnetize the disc. For example amplifiers
and loudspeakers never correct signals that have been damaged by magnetization.
Your amplifier and loudspeakers will simply reproduce the information that they
receive, good or bad signals. Demagnetizing the disc is indispensable if you are
to reproduce the music and images to the highest possible quality and to
retrieve all of the original information.
The Acoustic Revive RD-3 is a wonderful product.
It completely demagnetizes optical discs such as CD, CD-R, DVD, MD, and it is
easy to use.
If you use the RD-3 and demagnetize your disc, you will find that sound and picture quality are much improved. You will be able to hear aspects of the recording that were inaudible before the disc had been magnetized.
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 magneticfield is generated. If 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.
So the RD-3 is also very useful as a demagnetiser of cables and connectors.
The RD-3 one of the best and easiest upgrades you can make to your listening experience !
