Issues pertaining to the realisation of areal recording densities in excess of 1 Tbit / in2 are discussed. Using a composite media structure with well defined magnetic and microstructural properties the potential for achieving 1 Tbit / in2 using existing methodologies is clear. Higher densities will require the use of additional technologies.
