摘要： 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.
