Could anyone explain how do these wires work and how can they hold audio of this quality?

- DanBC 12y agohttps://en.wikipedia.org/wiki/Wire_recording https://en.wikipedia.org/wiki/Wire_recording You magnetise a wire to record; you read the magnetised wire to playback. You run the wire fast to get adequate bandwidth - the linked WP article says 2200 m for one hour of recording. (2 feet per second).
- jacquesm 12y agoIt's basically the fore-runner of the tape recorder. The fields used are much higher strength (as is the wire speed), the steel wire used was processed to make it easy to magnetize. There is nothing 'special' about it, it's just the same principle as magnetizing a needle with an electromagnet only you move the needle as you go and you alternate the current in the electromagnet with the sound you wish to record. Then later when you move the wire past the head it will induce an electric current which you can amplify.
