Demagnetizer for a magnetic head of a cassette tape recorder

A magnetic head of a cassette tape recorder set is demagnetized by a demagnetizer mounted in a tape cassette housing. The demagnetizer has an erase head which faces with the magnetic head which is subject to a demagnetizing action, a pair of rotatable rings which engage with spindles of the tape rec...

Zusammenfassung:A magnetic head of a cassette tape recorder set is demagnetized by a demagnetizer mounted in a tape cassette housing. The demagnetizer has an erase head which faces with the magnetic head which is subject to a demagnetizing action, a pair of rotatable rings which engage with spindles of the tape recorder set, energizing means for energizing said erase head with AC decreasing current, and coupling means for coupling said rings for simultaneous rotation of the rings.
