Professor Emeritus Shunichi Iwasaki and Tom Coughlin at PMR Milestone Ceremony in Sendai. On October 9, 2023 I attended the IEEE Engineering Milestone for Perpendicular Magnetic Recording (PMR) in ...

In a recent article in Acta Materialia authors from Seagate, NIMS and Tohoku University demonstrated two-layer heat assisted magnetic recording. The research team combined experimental measurements as ...

We've covered Seagate's HAMR, or Heat-Assisted Magnetic Recording, tech for HDDs, which is set to breathe new life into traditional platter-based storage by dramatically increasing the potential ...

Shingled Magnetic Recording (SMR) technology represents a significant evolution in data storage, enabling enhanced areal densities by overlapping recording tracks. This design increases storage ...

Forward-looking: Magnetic storage technology in hard disks has undergone significant evolution in recent years. Following Perpendicular Magnetic Recording (PMR), Shingled Magnetic Recording (SMR), and ...

Laser heating generates a temperature gradient in the MnPt layer, which induces spin currents (green arrows) that are injected into the FePt layer. These spin currents generate spin torque, which ...

Schematic view of (top) currently used HAMR and (bottom) three-dimensional magnetic recording systems. In the three-dimensional magnetic recording system, the Curie temperature of each recording layer ...
