Manufacture Head Surface TRIZ Cases
- Self-Aligned MAMR Head STO and Main Pole Alignment
Single mask ion beam etching aligns the spin torque oscillator with the main pole, preventing accidental erasure of adjoining tracks during magnetic recording.
- Magnetic Transducer Gap Segmentation for Throat Height Control
Segmented gap layers reduce effective throat height, enabling thicker trailing shields to improve magnetic shielding performance.
- STT Device Template Layer Reduces Critical Current Density
A template layer beneath a Heusler alloy free layer reduces critical current density in spin transfer torque devices.
- Evaporation Deposition Write Pole Fabrication
Evaporation deposition fills a patterned dielectric trench to create void-free write poles, overcoming CVD-induced stress and non-uniformity.
- Magnetic Head Stacked Body with Iridium Layer for High Density Recording
An iridium layer reverses magnetization in a magnetic head stacked body, maintaining effective field application despite reduced write gaps.
- Adaptive Side Gap Writer for TAMR and MAMR Writability
Thin magnetic layers in the side gap adapt permeability by frequency, resolving the trade-off between bit sharpness and writability.
