By demagnetizing CDs and DVDs, you can restore high-quality sound and image. This technique is commonly used by recording companies.
The primary reason discs become magnetized is due to the presence of iron in the paint used for printing labels. Iron oxide is used for red, yellow, and brown colors, cobalt for blue and green, and nickel for silver. These materials are “ferromagnetic,” meaning they are highly susceptible to magnetic influence. Another cause is the aluminum used on the signal side of CDs. The current standard for aluminum purity is 99.0%, with the remaining 1% containing ferromagnetic materials like iron, nickel, and cobalt. Aluminum itself is also a “weak magnetic material,” and all of these materials are susceptible to magnetic influence. When a disc containing such magnetic materials is played, the magnetic flux generated by the pickup and the disc’s drive motor further magnetizes the disc.
The multi-purpose audio demagnetizer “RD-3” is a groundbreaking product that can easily and reliably demagnetize all kinds of media, including CDs and DVDs. Users will experience audible and visual effects, such as being able to hear sounds that were previously inaudible and improved image quality and color development. Additionally, when making digital or video recordings on CD-Rs or DVD-Rs, demagnetizing the disc with the RD-3 beforehand can significantly improve sound quality, surpassing the influence of factors such as equipment quality or software compatibility. For these reasons, the RD-3 is widely used in the mastering rooms of major recording studios. Moreover, for discs, it is even more effective to use this unit in conjunction with the negative ion generator RIO-5Ⅱ.
The data graph shows that the magnetized disk has reduced reading accuracy, which prevents accurate playback. In other words, unless the disk is demagnetized, even high-quality playback equipment won’t be able to accurately read the information, and the disk won’t be able to be played in a “pure” state.
(The signal is not just a 1KHZ sine wave, so other band signals are also output.)
In the data before demagnetization, peaks other than sine waves are observed in the signal area of plate number 1. These peaks are likely caused by noise or distortion. Additionally, there is a blank space in the same area, indicating a potential loss of audio due to a reading error. Moreover, the stretched horizontal peaks suggest poor rise and fall of the sound.
The multi-purpose audio demagnetizer “RD-3” is a revolutionary product capable of easily and reliably demagnetizing various types of media, including CDs and DVDs. Users can expect audible and visual improvements, such as being able to hear previously inaudible sounds, and enhanced image quality and color development.
Furthermore, pre-demagnetizing CD-Rs or DVD-Rs with the RD-3 before making digital or video recordings can significantly enhance sound quality, surpassing the impact of factors such as equipment quality or software compatibility. As a result, the RD-3 is widely used in the mastering rooms of major recording studios.
To further enhance its effectiveness with discs, this unit can be used in conjunction with the negative ion generator RIO-5Ⅱ.
Please take note of the following text: If you examine the graph after demagnetization, which is highlighted in red from 1KHZ to 5KHZ at around 20 seconds, you will notice that the number of peaks has increased compared to before demagnetization. This indicates that the amount of information has increased as a result of demagnetization.
In simpler terms, after demagnetization, you will be able to hear sounds that were previously inaudible. Moreover, the height of each peak is greater after demagnetization, indicating that each range has been expanded.
The low output level PWL (db) of the RDYUMI is likely due to a significant reduction in noise components. However, when analyzed, the peak levels are increasing, indicating that degaussing with the RD-2 can boost the music signal level and reduce the noise components, leading to a significant reduction in distortion rate.
Furthermore, when using a product from another company (which uses an imported rotating magnet), a decrease in the signal-to-noise ratio was observed, believed to be caused by static electricity generation and reverse magnetization.
Before degaussing, the disk’s read speed was 590KB/s, and the overall score was 65 points. After degaussing, the read speed increased to 620KB/s, and the overall score rose to 69 points. This demonstrates the definite effect of RD-3 on CD-ROMs. Problems such as the inability to read or write can occur over time with CD-ROMs and RAM, often due to magnetism (magnetization), scratches, or defects in the disk. In many cases, degaussing with RD-2 can restore the disk to its original state.

BLER Block error rate: The number of block errors that can be detected by C1 in a 1-second block
The number of block errors that can be detected by C1 in a 1-second block
● Meaning of each error code
Indicates that an error was corrected at either the C1 or C2 stage.
E11 Indicates that one error was corrected at the C1 stage. (There may be some variation due to dust, etc.)
E21 Indicates that two errors were corrected at the C1 stage.
E31 Indicates that three or more errors were corrected at the C1 stage.
This error cannot be corrected at the C1 stage, so it is sent to the C2 stage.
E12 Indicates that one error was corrected at the C2 stage. (There may be some variation due to dust, etc.)
E22 Indicates that two errors were corrected at the C2 stage.
E32 Indicates that three or more errors were corrected at the C2 stage.
This error cannot be corrected.

TE32 Total of E32
■ Description
The totals of E22 and E32, which are important for sound quality, have been significantly reduced. With the E-22, the re-reading can increase jitter, and with the E-32, it can result in a complete error (unable to read) and loss of sound.
Sure, here is the revised text: “RD-3’s effectiveness is supported by data. The data shows that undegaussed disks have a significant amount of distortion and noise, and some may even have missing sound. If you do not degauss them with RD-3, you will continue to experience distortion, noise, and missing sound.
This occurs because CD players, amplifiers, and speakers can only amplify the information stored on the disc and cannot correct it. Therefore, would you choose to listen to or watch “dirty, damaged sound and images” without demagnetizing the disc?”
