The global HDD Head Gimbal Assembly (HGA) market is estimated at US$ 4.27 billion in 2025 (base year), forecast to reach approximately US$ 7.05 billion by 2031, a CAGR of 8.7% across 2025–2031. In volume terms, the market is estimated at 1,219.2 million units in 2025, expanding to approximately 1,502.0 million units by 2031.

This market's structure is directly confirmed by a primary source: TrendFocus Inc., via StorageNewsletter, states TDK Corporation (via its SAE Magnetics head business) is the sole independent merchant HGA supplier, with Seagate and Western Digital both fully captive.
