118 years of magnetic recording: impact and challenges ahead The dramatic increases of storage densities of magnetic recording over the last 60 years and the corresponding decrease in cost has helped drive the modern digital data world. However as many of the critical dimensions approach the nanometer scale, a variety of physical phenomena are placing limits on the increases of the capacity of future magnetic recording. I will review the evolution of magnetic information storage, its impact on the digital data and the current state of the art. I will then discuss new challenges of the energy use of digital data and the potential for a new generation of magnetic storage and non-volatile memory technologies to address these needs. _ _ _Dr. Fullerton is an internationally acclaimed scholar in areas such as thin film and superlattice growth, magnetic recording and nano-technologies, and x-ray and neutron scattering. At IBM/Hitachi, Dr. Fullerton made fundamental advances in the development of high density magnetic recording media based on anti-ferromagnetically coupled ferromagnetic films. Early in his career, he developed a technique for mapping the structure of thin-film multi-layers from x-ray diffraction data that became the standard in the field._ **Host** : A. Berger
