Limits of Storage in Magnetic Materials

Published

Author(s)

Thomas J. Silva

Abstract

I summarize what is currently known about how thermal effects limit the storage capacity of magnetic disk drives. The physics of thermal fluctuations in magnetic materials is treated in some detail, though the essential points are covered in a tutorial manner.
