In conventional heat-assisted magnetic recording (HAMR), a laser is used to locally heat the recording medium to facilitate data writing. However, the thermal energy applied is largely dissipated ...

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 ...

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 ...

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, ...

Use left and right arrow keys to seek audio. 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 ...

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 ...

Use left and right arrow keys to seek audio. 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 ...

The hard drive world is about to enter unchartered territory as the first 30TB heat-assisted magnetic recording (HAMR) drives have finally arrived. Seagate has been locked in a race to 30TB with its ...

Seagate Technology Holdings plcSTX is strengthening its competitive position through the rapid adoption of its Mozaic ...

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 ...

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 ...
