Driven by an explosion of data creation and retention needs, hard-disk-drive (HDD) storage capacities and data-center densities are rapidly expanding thanks to a technology called shingled magnetic ...

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 ...

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 ...

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 ...

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 ...
