摘要： The invention relates to a degaussing device for magnetic data carriers, comprising an AC-operated electromagnet which is provided with at least one excitation winding (1). The data carrier/s is/are moved by the yoke of said electromagnet, which is located on both sides of the data carrier/s that is/are to be degaussed, by means of a conveying mechanism. The at least one excitation winding (1) of the electromagnet is connected to at least one capacitor (5) so as to form a resonant circuit which is powered via an inverter (6).

摘要： A recorded data erasing device of a magnetic storage for erasing data of the magnetic storage M with a magnetic field generated from a coil (3) by discharging a charge in a capacitor (5) to the coil (3), wherein the inductance H and the internal resistance R of the coil (3) and the applying voltage V of the capacitor (5) are set such that a rebound phenomenon, where the orientation of the magnetic field is switched by a current flowing reversely through the coil due to polarity change of a transient voltage at the time of discharge, occurs at least once. Recorded data can thereby be erased completely or substantially completely from the storage medium of the magnetic storage M.

摘要： One or more pairs of magnet assemblages (14 and 16) are provided with magnetized segments (21-30) arranged in a Halbach-like array. The magnet assemblages (14 and 16) define a gap (18) through which magnetic data storage media (12) pass in a direction (20) across the segments (21-30). The magnetized sides (36) of the magnet assemblages (14 and 16) face each other thereby creating strong magnetic fields which degauss the magnetic data storage media (12) passing through the gap (18).
