At the heart of the company’s innovation breakthrough is the "spin torque oscillator" used to generate a microwave field that increases the ability to record data at ultra-high density without sacrificing reliability. Western Digital’s innovative MAMR technology is expected to offer over 4 terabits-per-square-inch over time. With sustained improvements in recording density, MAMR promises to enable hard drives with 40TB of capacity and beyond by 2025, and continued expansion beyond that timeframe.
