Frequently asked questions

What is the size of the global HDD Head Gimbal Assembly (HGA) market?
The market is estimated at US$ 4.27 billion in 2025 (base year) and is forecast to reach approximately US$ 7.05 billion by 2031, growing at a CAGR of 8.7% over 2025–2031.
How many companies actually make HGAs?
TrendFocus (via StorageNewsletter) directly confirms TDK Corporation is the sole independent merchant supplier of complete head gimbal assemblies, with Seagate and Western Digital both producing HGAs in-house (captive, not sold externally). NHK Spring supplies only the bare suspension sub-component, a narrower product scope than the complete HGA.
What is driving growth in this market?
AI and hyperscale nearline data center demand is the primary driver — TrendForce forecasts 23% CAGR (2025-2030) for nearline HDD shipments, and nearline drives require substantially more platters and heads per unit than consumer drives.
Which countries are covered in the report?
The report provides country-level forecasts for Thailand, Philippines, China, Japan, and Singapore, reflecting TDK's actual disclosed manufacturing footprint.
What years does the market data cover?
Historical data spans 2022–2025 with forecasts through 2031, covering both value (US$) and volume (million units).
What formats is this report available in?
The report is available as a PDF, with an accompanying Excel data annex containing all forecast tables.
