The wand's advantage lies in its demagnetizing other metal parts of the tape path, not just the heads. Used carelessly, it can increase the magnetization of the heads; if used too close to tapes, it can erase them. Both of these types of demagnetizer contain electronic circuitry and require a power source (either a battery or a power cord).
A tape head cleaner is a substance or device used for cleaning the record and playback heads of a magnetic tape drive found in video or audio tape machines such as cassette players and VCRs. [1] These machines require regular maintenance to perform properly.
In tape recorders such as reel-to-reel and compact cassette audio tape recorders, remnant magnetic fields will over time gather on metal parts such as guide posts tape heads. These are points that come into contact with the magnetic tape. The remnant fields can cause an increase in audible background noise during playback.
A tape head is a type of transducer used in tape recorders to convert electrical signals to magnetic fluctuations and vice versa.They can also be used to read credit/debit/gift cards because the strip of magnetic tape on the back of a credit card stores data the same way that other magnetic tapes do.
The magnetic material is normally in the form of tape, with the tape in its blank form being initially demagnetised. When recording, the tape runs at a constant speed. The writing head magnetises the tape with current proportional to the signal. A magnetisation distribution is achieved along the magnetic tape.

Key takeaways. Prolonged exposure to magnets can affect the functionality of your credit card. Cards with magnetic strips can also become demagnetized due to dirt, scratches and other damage.
