Heat assisted magnetic recording (HAMR) is considered to be the next major hard disk drive (HDD) technology for areal densities beyond ∼1.5 Tb/in2 [1]. In HAMR, each high anisotropy magnetic grain is heated close to, or above, its Curie temperature (Tc), then freezed in a new magnetization direction with an effective magnetic field as the grain cools down. As recent theoretical recording simulations...
This paper presents a computer-controlled test platform for superconducting magnetic energy storage (SMES) control and measurement based on the Laboratory Virtual Instrument Engineering Workbench (LabVIEW). The purpose is to achieve the fast control and friendly measurement simultaneously by integrating the LabVIEW and commercial digital control chips. The test platform mainly consists of three modules,...
