| 摘要 |
A device is disclosed for activating and deactivating magnetic electronic article surveillance (EAS) markers, and particularly those EAS markers that are associated with magnetically recorded media. In one embodiment, the device includes control circuitry comprising a coil, such as a solenoid-type coil, that provides a substantially uniform magnetic field that reliably activates and deactivates the marker, yet doesn't damage the magnetically-recorded media. |
