• Seagate is ready to purchase Intevac, a specialist in HAMR drive manufacturing
  • HAMR is seen because the know-how which goes to drive HDDs to 100TB+
  • The transfer is a critical blow to Western Digital and Toshiba’s personal HAMR plans

Seagate is charging forward in its quest to provide super-sized HDDs. In direction of the top of January 2025, the world’s largest exhausting drive vendor introduced a 36TB model – arriving only a month after it debuted a 32TB one – and it revealed on the time {that a} 60TB drive is on its means.

Now, the agency has introduced plans to accumulate Intevac, an organization identified for making sputtering methods that apply ultra-thin layers of fabric, resembling an iron-platinum alloy (FePt), to HDD platters. This superior deposition course of permits for the creation of magnetic layers with larger uniformity, improved signal-to-noise ratios, and fewer defects, doubtlessly leading to denser knowledge storage. Over 65% of the world’s exhausting disk output is produced utilizing Intevac’s methods, which works out to greater than 50 million disks per thirty days. The know-how is taken into account important for Perpendicular Magnetic Recording (PMR) and Warmth-Assisted Magnetic Recording (HAMR).
