Abstract:
1. A magnetic recording medium, comprising: a substrate having a surface; a nanoparticle layer comprising an array of nanoparticles having an average particle size of at least 1 nm and not more than 20 nm, consisting of metal elements and containing at least one element selected from the group consisting of Fe, Co, Ni, Mn, Sm, Pt, or Pd; and an organic compound located between said array of nanoparticles, wherein an easy axis of magnetization of said nanoparticles is orientated substantially parallel to a direction which is at a particular angle to said substrate surface, and wherein said crosslinking agent has a structure selected from those represented by the general formulae (1) to (4): wherein R1 to R9 are independently a functional group selected from the group consisting of carboxylic acids, phosphonic acids, phosphinic acids, sulfonic acids, sulfinic acids, thiols, hydroxyls, and a hydrogen atom; or a hydrocarbon group containing carbon-carbon double bond or ether bond.
