Hi
I live in the UK and I am looking for a way of creating the title matter. 'A Bulk Floppy Eraser'. I have looked online and there are a number of old products for sale usually tape reel erasers, these will do but getting them from the US to the UK is expensive, also buying new or from china at high costs area non starter.
So. I was thinking how difficult can it be to construct one, as I understand it, the media must be left in a neutral state, so simply wiping a magnet around a disk does not do the trick.
It should be a coil which generate an alternating magnetic field, and start as strong at it needs to be and then reduces its power over say 10 seconds to nothing thus eliminating greatly any magnetic polarisation on said media, in this case a stack of floppy disks I need to wipe as they have been used on different systems to the ones I want to use them on and the goal is to remove any magnetic residue/markers from them so they can be reused as they are simply not manufactured anymore.
So if anyone can come up with a fairly simple design, then I can make it. I just don't have any idea about building things with coils to so something like this although I'm ok with general electronics.
Any help will be appreciated.
Thank you
