ABSTRACT:
A magnetic recording disc is provided according to the present invention for magnetic recording. The magnetic recording disc includes a disc substrate having a locking pattern etched therein. Chemically synthesized iron-platinum particles are provided in the locking pattern and completely fill the locking pattern. The chemically synthesized iron-platinum nanoparticles exhibit short-range order characteristics forming self organized magnetic arrays.
