US Patent 7208204 - Nanocluster magnetic recording media

This patent from Singapore's Agency for Science, Technology, and Research focuses on the fabrication of magnetic recording media with smaller grain size via the use of nanoclusters and with improved grain distribution width control. Claim 1 reads:

1. A method for forming a thin film magnetic recording media, the method comprising: generating magnetic nanoclusters in gas phase; heating the magnetic nanoclusters; crystallizing the magnetic nanoclusters; and depositing the magnetic nanoclusters onto a substrate to form a thin film of magnetic particles thereon; wherein the generating, heating, crystallizing, and depositing steps are performed sequentially.
