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 ...

Research groups have made a breakthrough in the field of hard disk drives (HDD) by demonstrating the feasibility of multi-level recording using a three-dimensional magnetic recording medium to store ...

Data growth is estimated to double between 2022 and 2026 and with that growth in data the amount of data retained is increasing. Although NAND flash memory-based SSDs are growing in importance for ...

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 ...

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 ...
