Heat-assisted magnetic recording (HAMR) (pronounced " hammer ") is a magnetic storage technology for greatly increasing the amount of data that can be stored on a magnetic device such as a hard disk drive by temporarily heating the disk material during writing, which makes it much more receptive to magnetic effects and allows writing to much sma...

HAMR is the next significant innovation to increase “areal density”—the amount of data stored on a disk. HAMR will fuel hard drive product development and growth through the next decade.

Jan 21, 2025 · Unrivalled Areal Density: Exos M, powered by HAMR-based Mozaic 3+ platform, now delivers capacity points up to 36TB through a highly efficient 10-platter product design. Seagate is the only data storage company that can achieve areal densities of 3.6TB per hard drive platter today, with a pathway to increasing per-platter capacity to 10TB.

To build a HAMR drive, we had to: • Add a laser diode to the head • Develop an optical path to steer the light from the laser to the NFT • Integrate NFTs into the recording head • Develop new HAMR media • Modify the firmware on the drive and in our test systems • Adjust our manufacturing process to accommodate HAMR

Feb 14, 2025 · Western Digital this week outlined its future hard disk drive technology roadmap and revealed plans to adopt heat-assisted magnetic recording (HAMR) for its HDDs beginning in late 2026. HAMR...

Dec 18, 2024 · HAMR technology revolutionizes data storage in hard disk drives. Heat-assisted magnetic recording (HAMR) allows for smaller, more densely packed data bits on disk platters, greatly increasing storage capacity.

13 hours ago · Race to 100TB HDD heats up as Seagate pulls rug under Western Digital, Toshiba feet by acquiring HAMR-specialist Beyond 100TB, here's how Western Digital is betting on heat dot magnetic recording ...

Feb 22, 2025 · Our ultimate plan is to deliver HAMR when it reaches economic crossover for everyone. Beyond HDD, our teams are exploring new growth opportunities that leverage our core capabilities in magnetics and materials science, and with their dedication, the possibilities for future applications of our technologies are truly endless.

Feb 17, 2025 · HAMR (Heat-Assisted Magnetic Recording) allows more data to be stored on hard drives by heating the magnetic medium. This technology significantly increases storage density, with forecasts to reach up to 100 TB per unit in the future.

Jul 30, 2020 · Heat-assisted magnetic recording (HAMR) and microwave-assisted magnetic recording technology (MAMR) appear to be the next. The HAMR vs. MAMR contest may not be decided for some time, but it will influence the types of HDDs being used in the cloud and in data centers in the future.
