Scientists have demonstrated a new recording principle that improves recording efficiency by 35% by combining spin torque with conventional heat-assisted magnetic recording (HAMR). This advancement is ...

Heat-assisted magnetic recording harnesses a near-field optical transducer to deliver nanoscale heat spots that locally raise the recording medium’s temperature toward or above its Curie point, ...

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 ...

Forbes contributors publish independent expert analyses and insights. I attended the 2024 IEEE Magnetics Society TMRC conference at the University of California in Berkeley. The sessions I attended ...

Forward-looking: Heat-assisted magnetic recording is a technological breakthrough that has been decades in the making. The first patent describing a method for using heat to record data through a ...

We've been following Seagate's HAMR or Heat-Assisted Magnetic Recording storage tech for a while now, with this new take on the traditional HDD created to deliver customers the highest capacity and ...

Toshiba has demoed 32TB (terabyte) and 31TB hard disk drives (HDD) that use heat- and microwave-assisted magnetic recording (HAMR and MAMR) plus shingled drive tracks to boost capacity over existing ...

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 ...
