由於CD或SACD盤的印刷面或信號面鋁箔中含有的磁性體帶磁，因此音質和畫質明顯產生劣化現象。

通過RD-3進行消磁，可以減少出錯率和波動，能夠正確讀出盤中原始的資訊，提高了S/N比及影像定位，減少失真，能夠獲得音場放大等高品質的音質和畫質。進而，可以對CD-R或者DVD-RW等記錄介質實施錄音前的消磁，能夠獲得沒有出錯的高品質的錄音和錄影效果。對電纜和端子等的消磁也非常有效果。

Description:

The presence of magnetic particles in the printing surface or signal surface aluminum foil of CD or SACD discs causes a noticeable deterioration in sound and image quality.

By using RD-3 demagnetization, error rates and fluctuations can be reduced, allowing for the accurate reading of the original information on the disc. This improves the signal-to-noise ratio (S/N ratio), image positioning, and reduces distortion, resulting in high-quality sound and image quality, including enhanced soundstage amplification.

Furthermore, demagnetization before recording on recording media such as CD-R or DVD-RW can ensure high-quality recording and video effects without errors. Demagnetization also proves to be highly effective for cables and connectors.
