Title: Ultrathin carbon coatings for magnetic storage technology

Authors: John Robertson

Addresses: Engineering Department, Cambridge University, Cambridge CB2 1PZ, UK

Abstract: The production of protective carbon coatings for magnetic storage densities up to 1 Tbit/in² is discussed. The need for a continuous coating is described in terms of its surface roughness. This is achievable for depositions with ion energies of 30 eV or over. Characterisation methods such as X-ray reflectivity, photoemission and Raman are described.

Keywords: diamond-like carbon; deposition; characterisation; surface roughness; bonding; Raman; corrosion protection; ultrathin coatings; carbon coatings; magnetic storage technology; X-ray reflectivity; photoemission.
