Yes, when I had a vinyl rig, and what a rig it was, I used a demagnetizer on records, with the Radio Shack bulk tape eraser one had to take care to pull the eraser away from the record to some distance prior to releasing the power button otherwise the magnetic field might otherwise be placed back on the just demagnetized record. One assumes this procedure also applies to "passive" devices such as the Walker Talisman, which I understand has rows of neodymium magnets at offset angles, but I haven't opened one up to confirm this as they're a little expensive. ;-). Other things I routinely demagnetize include the magnetic tape head on my Sony and Aiwa and other portable cassette players, the leads on my lightweight Sony heasphones, the portable CD player unit which can be demagnetized as a whole using a few sweeps of the Talisman. Prior to going all portable, back when I had my tube headphone amp and Sennheiser headphone set up I found using the Talisman on RCA jacks, the magnetic screws of the amp, interconnects and internal wiring of the (open) modded Oppo to be beneficial. Some of these demagnetizer applications are easier to explain than others, I'm afraid. :-).

That might very well be true. But I think I'll stick to my trusty Walker Talisman and forego heating, dropping from a height or hammering my CD player, my CDs and my vinyl (assuming I had any). It's much more forgiving. :-)

Whilst demagnetizing your audio tape player, which I do myself for my portable Sony Walkman cassette player from time to time as well as clean the tape head with a Q tip and alcohol, make sure you have no cassettes in the vicinity that might be adversely affected by the demagnetized. I use a Walker Talisonman but any demagnetized will do. If you use an electronic demagnetizing turn the thing ON away from the tape player then pass the demag over the tape head several times. Take the demag away from the player before turning the thing OFF otherwise you can inadvertently place a magnetic charge back on the tape head. Don't worry about demagnetizing anything else besides the tape head.

I have read that shack bulk tape erasers are having a positive effect when it is used on cds, does anyone try this before?

Yes, I used a Radio Shack bulk tape eraser for many years on CDs and interconnects with positive results.

Frankly speaking, I had no idea how do CD demagnetizers world until your questions. As I`m working as a freelance paper writer here and usually read a lot to write a research paper, I decided to investigate this problem. I found out that there are really many ways to demagnetize something. For example, you can easily do it by tapping, heating, hammering. Anyway, you can visit this site https://www.smartpaperhelp.com/ and get all the answers.

Thanks for posting. While you're investigating magnetization how about investigating how any method of demagnetization can have an effect on a CD which ostensibly has no magnetizable parts. Furthermore how about investigating why demagnetizing a CD would change the sound even if the CD contained magnetizable elements. Thanks in advance.
