Abstract
Methods and apparatus are provided related to magnetic recording tape. One or more ion emitters are disposed in non-contacting proximity to a passing recording tape. Static electric charges born on the tape are neutralized prior to passing the tape in contact with a read-write head. Migration of chemical constituency from the tape to the head is prevented or significantly reduced with a corresponding elimination or reduction of related problems.
