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.
