Seagate10-K: Legacy modernization

Betting on Mozaic platform and HAMR technology to modernize its core HDD portfolio

What happened

Seagate is driving a major technology transition to its Mozaic platform, featuring HAMR (heat-assisted magnetic recording), to achieve higher storage densities. This strategic shift requires significant R&D, manufacturing retooling, and supply chain coordination to replace older technologies and maintain a competitive edge.

Annual report (Form 10-K)

Seagate 10-K for FY2026

Filing excerpt

Our technology roadmap is centered on advancing areal density, which increases the amount of data that can be stored on a disk's recording surface. Through innovations such as our Mozaic platform, which incorporates our unique implementation of heat-assisted magnetic recording ('HAMR') technology, advanced magnetic recording with proprietary photonics and other innovations, we enable higher storage densities and drive capacities in a capital efficient manner.
