Heads Using Thin Films TRIZ Cases
- Dual-Layer Nonmagnetic Cap for Reactive Ion Etching in DFL Read Heads
A dual free layer read head uses a segmented nonmagnetic cap with distinct etch selectivities to enable precise reactive ion milling.
- Thermal Assisted Magnetic Recording Head Plasmon Generator Metal Layer
Surrounding the waveguide with a metal layer generates localized surface plasmons that concentrate heat, reducing the heating range on magnetic media.
- Magnetic Head Side Shield Segmentation for Perpendicular Recording
Segmented side shields expand the main pole cross-sectional area near the medium facing surface to enhance write performance.
- Ultra-thin Micro-components Using Stress Compensation Layers
Stress compensation layers eliminate warping in ultra-thin components, removing the need for thick rigid substrates.
- Magnetic Recording Device Triangular Wave Current Stabilization
A magnetic recording device supplies direct current to the pole and shield while driving a coil with a triangular wave.
- Magnetic Reader Crystal Decoupling Structure for Exchange Coupling
An amorphous intermediary layer prevents shield crystallization propagation, resolving trade-offs between annealing temperature and tunneling barrier quality.
- NiFe Touchdown Sensor Stabilization via RuOx Seed and Ru Capping Layers
RuOx seed and Ru capping layers block atomic diffusion in NiFe sensors, preserving temperature coefficient of resistivity during thermal cycling.
- Selectable Trapezoidal Read Sensors for Data Storage Precision
Selectable trapezoidal read sensors use multiple tip positions to identify the optimal electrical reader width during fabrication.
- Recessed Antiferromagnetic Stitch Layers for Read Gap Reduction
Segmenting pinned layers and recessing the antiferromagnetic layer reduces read gap thickness while maintaining pinning field strength.
- Partial Etched Polyimide Adhesive Containment for Disk Drive Suspensions
Segmented insulation gaps contain epoxy to prevent electrical shorts between conductive materials and metal layers.
- Spin Torque Oscillator Using (001)-Oriented Heusler Alloy
A spin torque oscillator uses a (001)-oriented Heusler alloy in the spin injection layer to enhance spin polarization.
- Magnetic Recording Heads with FeCr Dusting Layers for Spin Torque Control
FeCr dusting layers reduce spin torque and cross-track forces, enabling thinner material stacks and higher recording densities.
- Write Head Side Shield Magnetization Detection
A write head measurement method detects reversed side shield magnetization conditions using recorded signal patterns.
- YIG-Heavy Metal Write Head Reducing Flux Shunting
A magnetic recording head uses a yttrium-iron garnet layer to conduct spin current while blocking electrical shunting.
- Microwave-Assisted Magnetic Recording Head With Segmented Spin Torque Oscillator
Segmenting the spin torque oscillator prevents magnetic field leakage into the recording gap, enabling steep gradient fields for higher track density.
- Thin-Film Magnetic Recording Head Light-Absorbing Layer
A thin-film magnetic recording head incorporates a light-absorbing portion between the main magnetic pole and underlying sensor or heater.
