Abstract

We have been experimenting with overwriting by magnetic field modulation using flying magnetic heads and single-sided disks. We developed a new protective layer for the disks. This is a spin-coated polymer layer containing α-Fe₂0₃ powder. It holds lubricating oil well and increases durability. We obtained good read-write characteristics using the protective layer on a reflective structure disk.
