Thermal effects and media performance at high recording densities

Thermal effects in thin film media have interesting. if not potentially serious implications for both short~tenn writing and long-term storage of recorded data. Remanent-moment thickness product (M,T) and grain size reduction for enhanced media performance, in conjunction with increasing areal densities, make thermal effects important considerations in the design and characterization of advanced recording systems. This talk will discuss both the short- and longterm manifestations of thermal effects in thin-film media, dynamic coercivity and thermal decay, as well as the measurement of, and correlation between these two phenomena.
