The background of magnetic information storage technology is first introduced, followed by a brief summary of the 100-year-evolution of the magnetic recording industry. Significant improvements in the technology have been strongly correlated to the advances in physics, material science, electrical engineering, mechanical engineering and computer science, although applied magnetics has been crucial toovercoming the bottleneck in information storage technology. In the third part, it is shown that the development of micromagnetics and information storage technology are strongly correlated. In the last part, new frontiers and future challenges are analyzed with respect to physics and related subjects.
