Heads Using Thin Films TRIZ Cases
- Multichannel CPP Sensor Array Milling for Tape Head Modules
A tape head module integrates an array of current perpendicular to plane sensors with controlled resistance values.
- Slider Lapping via Bias Current Thermal Expansion
Bias currents heat slider heaters to expand transducers, enabling precise material removal while managing current limits.
- Nonconductive Magnetic Shield Laminate for Tape Head Protection
Laminate pairs with insulating layers prevent electrical shorting and erosion in tape drive heads.
- Chromium Insertion Layer Spin Torque Oscillator for High Density Recording
A spin torque oscillator incorporates a chromium insertion layer to enhance oscillation angles at high frequencies.
- FeNi Alloy Magnetic Head Pole Layer for Perpendicular Recording
A FeNi alloy pole layer with controlled nickel content and tensile stress increases saturation flux density while suppressing the pole erase phenomenon.
- Magnetic Recording Head Negative Anisotropy Layer
Negative anisotropy on the main pole suppresses spin waves, maintaining stable oscillation and improving recording density.
- Recessed Antiferromagnetic Layer for Narrow Read-Gap Head
A magnetic read head uses a recessed antiferromagnetic layer to reduce the sensor read gap thickness while maintaining pinning stability.
- STT Device Oxide Seed Layer Spin Pumping
Oxide seed layer reduces damping to lower critical current.
- Near Field Transducer Anneal for HAMR Heads
Insulating layers facilitate antenna annealing without damaging read elements, resolving write field strength limits.
- Coplanar Dual Loop Reader Heater for HAMR
Segmenting the reader heater into coplanar loops lowers sensor temperature and improves read signal reliability by managing thermal constraints.
- Intermediate Layer for Thin-Film Magnetic Head Substrates
A thin-film magnetic head substrate incorporates a non-aluminum oxide intermediate layer between the ceramic base and undercoat film.
- Thin Film Magnetic Head Heating Element Electromigration Suppression
A thin film magnetic head heating element uses a high-melting-point-material layer to suppress electromigration in the conductor.
- Magnetic Sensor Side Shields with Extended Height
Side shields extend beyond the stripe height to eliminate material residue at the back edge, enabling higher areal density.
- Magnetic Head Main Pole Inclined Top Surface Design
An inclined main pole top surface positions a spin torque oscillator to prevent over-etching that reduces cross-sectional area near the medium facing surface.
- Varying Side Shield Gap Distal ABS for High Areal Density
Segmented sub-layers adjust gap distances to reduce adjacent track interference and erasure after write conditions.
- Thin Film Magnetic Head Heating Element Heat Dissipation
Electrode leads dissipate heat from a thin film magnetic head heating element, preventing local temperature increases and peripheral protrusion.
- Self-aligned Hybrid Au-Rh Near Field Transducer for TAMR
A hybrid near field transducer uses a rhodium peg layer to preserve thermo-mechanical stability while the gold resonator maintains optical transmission.
