A system including a magnetic tape processing system that includes a read/write head to write to a top surface of a magnetic tape. The read/write head provides a write head field gradient of at least 40 Oersteds per nanometer at the top surface of the magnetic tape. The magnetic tape processing system and the read/write head provide a track density of greater than 8000 tracks per inch, a bit density of greater than 440 kilo-bits per inch, and an aspect ratio of less than 70.

Magnetic tape processing

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.
