A few years ago I've tried to ressurect a few of my cooler floppies that had bad sectors and couldn't be formatted on my Jazzminuta - Various - The Low Times Of Hi-Fi (Floppy Disk) My approach was to leave them on my strongest speaker for about a day, then flip, and leave it for another day, then reformat and write.
Surprisingly, I've got a few of those fixed that way, but I doubt that leaving a floppy for a short time on a random speaker would do anything to it, not to Jazzminuta - Various - The Low Times Of Hi-Fi (Floppy Disk) playing music, which will do literally nothing in this case.
To really damage a floppy, you would need to hold it literally on the Nowell - Saint Johns Seminary Choir, Brighton, Massachusetts - The Heavens Declare - Christmas Hymn for extended periods of time, just like I did a few years back. This would still only damage the data, not wipe it clean. If you want to check what really happens with magnetic mediums placed on speakers, a good place to start would be to get a blank audio tape, record some music onto it, leave it on the speaker for a few days, and then play it back.
Notice that the sound will be much quieter with maybe some more hiss introduced. The hiss will be much more noticeable on silent sections. If you have a stereo player, you'll also be able to notice how one channel is much more quiet than the another.
You'll need a powerful magnet. You can either get it from a speaker, or make a strong electromagnet. Rub it on the magnetic tape repeatedly. That will corrupt the data on it, but I doubt that it'll erase it.
A loudspeaker has two magnets interacting: One Europe - Various - Uplifting Trance And Melodic Energy Trance Anthems Vol.
3, usually permanent one two-electromagnet seems to have gone out of fashion in prewar timesand an electromagnet the voice coil. The permanent magnet is what you would normally worry about, but the field emanating from it is relatively independent of whether the loudspeaker is silent or not - you would need to physically move the floppy closer to the magnet.
The electromagnet's strength is indeed dependent on sound input - how much of that magnetism actually leaves the loudspeaker is extremely dependent on the actual loudspeaker design at hand.
Conceivably, fields from both magnets adding up during a particularly loud sound event could overcome the coercivity of the floppy drive and indeed cause spurious erasure - all very dependent, again, on the exact loudspeaker. If you want to get an idea about magnetic fields in front of the loudspeaker - just find an old fashioned compass, it can tell you quite a bit. Home Questions Tags Users Unanswered.
Can a HiFi speaker erase a floppy Jazzminuta - Various - The Low Times Of Hi-Fi (Floppy Disk) Ask Question. Asked 1 year, 11 months ago. Active 1 year, 11 months ago. Viewed times. Can a speaker actually erase a floppy disk? How close does it need to be? It's the magnet in the speaker that's the problem, not the sound. Don't store floppy disks around magnets. You'd probably have better luck putting the floppy disk at the back of the speaker closer to where the magnet is.
You don't need to play any music. If it's loud enough to cause nuclear fission in the air, that floppy will get thoroughly wiped. Out of existence. That's a useless upper bound, but it's a start. Oh, and what happened to asking in chat first?
I don't think this Jazzminuta - Various - The Low Times Of Hi-Fi (Floppy Disk) a duplicate of the referenced question. One of the answers to the referenced question says "magnets can corrupt floppy disks" which is true but this question is asking how close the disk has to be to the magnet.
Stephen Kitt Stephen Kitt I remember the monitors with degaussing buttons. It just creates vibrations. It works just same as magnetizing a metal piece by rubbing a magnet on it. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.
