Three-dimensional magnetic recording
Simon John Greaves
Abstract
Magnetic recording in current hard disk drives is basically two dimensional, with information stored in a thin recording structure covering the surface of the disk. This review examines the prospects for three dimensional magnetic recording using multiple recording structures, and the technologies that may help its realisation. In particular, energy-assisted recording techniques are discussed as these appear to have the greatest potential.
