This lecture covers the evolution of magnetic storage techniques, from longitudinal to perpendicular recording, and heat-assisted magnetic recording. It explains the role of anisotropy energy in maintaining magnetization direction, the importance of Ku in writing fields, and the use of laser heating to decrease coercivity. Additionally, it discusses magnetic-core memory principles, core switching-induced voltage, and magnetoresistive RAM technology.
