The system comprises a magnetic tape processing system having a read / write head for writing on the top surface of the magnetic tape. The read / write head provides a write head magnetic field gradient of at least 40 oersted / nanometer on the top surface of the magnetic tape. The magnetic tape processing system and the read / write head provide a track density greater than 8000 tracks / inch, a bit density greater than 440 kilobits / inch, and an aspect ratio of less than 70.
