Isolated single-domain high-density magnetic recording media and method of manufacturing the media

摘要

A magnetic recording medium and a process for making the same provides a plurality of micro- or nano-machined recesses in a non-magnetic carrier layer. The recesses are machined by a fiber laser and when filled with a magnetic material, provide isolated single-domains on the magnetic recording media. The micro- or nano-machining of the recesses produces single domains of extremely small dimensions to increase the recording density on magnetic recording media.
