How does demagnetisation restore the top condition of the carrier?

The final production stage of a magnetic carrier is … demagnetisation. The metal particles on the carrier, which will later hold your magnetic information, are rearranged with a strong magnet in a random order. This will remove any possible signal. The carrier is virgin and ready for use. Your old discs and tapes are bursting with data. Maybe they've been overwritten a few times. Sometimes there are unintentional pieces of old data left behind. They slow down the computer's processing time. By regularly demagnetising your tapes and discs, all ghost signals disappear. Your carriers are returned to their original condition and you can start with a clean slate again.
