Seagate confirms that it will launch HAMR mechanical hard drives above 30TB in the third quarter of this year.

CTOnews.com, March 15 (Xinhua)-- Seagate confirmed this week that it will launch the world's first mechanical hard drive above 30TB using thermal-assisted magnetic recording (HAMR) technology in the third quarter of 2023, and promised to push it higher to 50TB in the next few years.

Seagate said it will soon launch 22-TB and 24-TB mechanical hard drives using perpendicular magnetic recording (PMR) and stacked magnetic recording (SMR) technology, although officials have not yet announced when it will be officially released.

Seagate CEO Dave Mosley (Dave Mosley), CTOnews.com translator, said: "We have met or exceeded all product development milestones and reliability indicators, and we will deliver pre-certification units to major cloud customers in the coming weeks.

The material of HAMR technology hard disk disk has been changed, using iron, platinum and other alloy materials, rather than the current mainstream hard disk disk is cobalt, platinum, chromium and other elements alloy. The most important feature of HAMR technology is the integration of laser emission components in the hard disk to provide the corresponding small laser beam to the write point in the way of near-field light, so as to heat the disk particles to assist the head to write.
