Manufacture Head Surface TRIZ Cases
- Thin-Film Magnetic Head Pole Width Uniformity
A thin-film magnetic head structure uses segmented resist layers to etch a base insulating layer depression, ensuring uniform magnetic pole widths.
- Magnetic Head Stacked Body Ru Layer Spin Polarization Stability
A magnetic head incorporates a stacked body with a ruthenium-containing non-magnetic layer to enhance spin injection efficiency.
- Asymmetric Magnetic Write Heads for Shingled Recording
Mirror image asymmetric write heads optimize data density and track pitch in shingled magnetic recording systems.
- Laterally Graded Spin Torque Oscillator Flux Guiding Layer
Lateral grading of the flux guiding layer reduces write bubble fringing by lowering current density requirements for magnetization reversal.
- Self-Aligned Spin Torque Oscillator for Magnetic Recording Head
A step structure aligns the spin torque oscillator with the main magnetic pole to stabilize high frequency field generation.
- Notched Pole Tip Shield for Magnetic Write Element
A pole tip shield with notched side shields creates an expanded non-magnetic gap region to enhance write field strength.
- Selective Wet Etching of Silicon Dioxide in Magnetic Head Poles
A high pH wet etching solution removes silicon dioxide matrices from magnetic head structures without damaging adjacent components.
- MAMR Head Slider DLC and SiN Protective Layer
A diamond-like carbon layer on a silicon nitride seed layer protects MAMR head sliders from wear.
- Cross-Track Current Design for Energy-Assisted Magnetic Recording
Insulation layers manage heat distribution to improve write field saturation while reducing localized heating issues.
- Dual Write Head Design for Magnetic Recording Density
A dual write head design with energy-assisted structures enables precise data writing.
- Graded Intermediate Layer for Magnetic Slider Protection
A graded intermediate layer composed of carbon and seed materials enhances adhesion and hardness on magnetic storage slider substrates.
- Patterned Leading Shield Notch for PMR Write Head
A patterned leading shield with a recessed notch releases magnetic flux to enhance overwrite capability in perpendicular magnetic recording heads.
- Data Reader Back Edge Surface Shaping for Magnetic Stability
Shaped back edge surfaces in data reader laminations resolve storage density versus magnetic stability trade-offs by reducing stray field impact.
- HGA Suspension Dimple Secondary Structure for Contact Point Restriction
A secondary structure on the primary dimple restricts the flexure contact point, preventing wear-induced axis shifts that degrade slider flyability.
- RF Data Writer Field Generator for High Density Storage
Selective activation of the magnetic feature generates concentrated RF fields that enhance programming gradients and precision.
- PMR Writer Pole Sidewall Angle Control
Damascene etching maintains constant sidewall angles to reduce on-track reverse overwrite loss.
- Multichannel Magnetic Recording Head With Scaled Reader Widths
Scaled reader widths in inner and outer transducer arrays reduce misregistration and congestion while doubling data rates for high-density tape storage.
- Tape Head Same Gap Verify Module Design
Integrating write and read transducers into a single module eliminates time delays between writing and verifying data on magnetic tape.
- Write Pole Box Shield with Multi-Layer Gap
Multi-layer gap structures enable milling instead of plating, resolving construction complexity while maintaining high write field gradients.
