Why do optical discs, such as CD, become magnetized?

Firstly, it is thought that ferrous ingredients 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 multi-purpose audio demagnetizer RD-3 is a ground breaking appliance which can easily treat and completely demagnetize all kind of optical discs (CD, DVD, etc). If you demagnetize your disc by RD-3, sound and picture quality are much improved and you will be able to hear aspects of the recording that were inaudible from magnetized discs.

RD-3 also has a remarkable effect on digital recording media such as CD-R, DVD-R. If a disc is demagnetized by RD-3 before recording, the sound quality improves greatly regardless of the recording device or software.
For this reason, the RD-3 is widely used in the mastering rooms of major recording studios.

The RD-3 makes a further effect by combined use with our Negative-Ion generator RIO-5II.

The data showing the effects of use

You can see on the graph of a disc before being demagnetized, the ability to read information deteriorates and prevents accurate reproduction.

This means, that unless the disc is demagnetized, any high quality disc player is unable to read correct information to create optimum sound playback.

The quality of a whole audio system improves drastically !

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. If the current stops, the magnetic field should disappear, however, the magnetic substances are contained in cable wires and connectors as impurities, the electric current magnetizes these substances, and this has a harmful influence on the signals or the flow of the current.

It is well known that magnetism has a bad influence on the quality of sound and picture reproduction. You can use the RD-3 for demagnetizing a wide range of equipment, such as CD stabilizers, metal parts and accessories, speaker terminals and so.

1. Measurement data of 1kHz signal

(Not only 1KHZ sine-wave but also other ranges of frequency are shown in the graph)

Before demagnetizing, peaks other than a sine-wave are generated at the 1kHz signal. We considered these peaks as noise or distortion. White blank fields at the 1kHz peak are considered to be caused by reading errors. The sideways peaks are considered to be the rise and fall of the sound becoming worse.

The multi-purpose audio demagnetizer RD-3 is an ground breaking appliance - easily treating and completely demagnetizing of all kinds of optical discs (CD, DVD, etc).

If you demagnetize your disc by RD-3, the sound and picture quality are much improved and you will be able to hear aspects of the recording that were inaudible from magnetized discs.

RD-3 also has a remarkable effect on digital recording media such as CD-R, DVD-R. If a disc is demagnetized by RD-3 before recording, the sound quality improves greatly regardless of the recording device or software.
For this reason, the RD-3 is widely used in the mastering rooms of major recording studios.

RD-3 makes a further effect by combined use with our Negative-Ion generator RIO-5II. The data showing the effects of use are shown here.

2. Measurement data of the music signal

With the post-demagnetization graph, the encircled areas, in the vicinity of 20 second in the range of 1 to 5Hz, it clearly shows filled in signal and increased crest height. The amount of information is therefore increased by demagnetization.

It is clear that you are now able to listen to sound that could not be heard before. The heights of the peaks also increase; it indicates that the respective ranges are extended.

3. Measurement of various data of music CD

Power Level
PWL(db)
Total harmonic distortion
THD(%)
Signal to Noise ratio
SNR(%)
noYUMI -13.36 72.11 2.047
UCYUMI -13.36 71.75 71.75
RDYUMI -13.94 70.99 1.866

At the PWL, value of RDYUMI is lowest, as noise is very low. And each peak level becomes raised when we confirm by analyzer, so demagnetizing a CD using the RD-III, increases the signal level and decreases noise. In addition, distortion decreases significantly. On the other hand, it shows that SNR becomes worse caused by generating static electricity or magnetism when the CD is demagnetized using by another product (imported product which uses a method of motor rotation).

  • Recording time of the track 4'45''
  • noYUMI: Reproducing a used music CD before demagnetization
  • UCYUMI: Reproducing a used music CD post demagnetization by other demagnetizer.
  • RDYUMI: Reproducing a used music CD post demagnetization by the RD-III

4. The effects on CD-ROM

READ(KB/s) Total
Before treatment 590 65
After treatment 620 69

Before demagnetization, read value is 590KB/s with 65 points in total. After demagnetization, read value is 620KB/s with 69 points in total. Read value is greatly increased. The RD-3 therefore has great effects on CD-ROM.
Incidentally, with CD-ROM or RAM, there are occasionally cases where problems are caused while using discs, such as It is not possible to read and It is not possible to write. It may be caused by the damaged surface of the disc or an inferior disc, but it is also caused by a magnetized disc in many cases. In these cases, it is possible that RD-3 can help to recover the disc.
