Combination Recording TRIZ Cases
- HAMR Medium Bilayer Structure for Reduced Laser Power
A thermal-transport-control layer in a HAMR medium reduces heat-sink thickness to lower laser power while maintaining high thermal gradients.
- Multilayer Near-Field Emitter for HAMR Head Thermal Management
A multilayer near-field emitter uses high extinction coefficient metal to confine plasmonic energy and produce a precise hot spot.
- Thermally-Assisted Magnetic Recording Head Main Pole Groove
A main pole with a groove concentrates magnetic flux at the track center, preventing adjacent track erasure while maintaining thermal stability.
- Near-field transducer thermal sensor write clock synchronization
A near-field transducer secondary tip heats a temperature sensor to detect optical power changes from magnetic data islands.
- Heat-Assisted Magnetic Write Head with Dielectric Clads
Dielectric clads concentrate light energy near the magnetic pole, reducing corrosion risk and improving recording density.
- Gradient-index lens with tilted sidewalls for laser coupling
Tilted sidewalls and graded refractive indices guide light into the waveguide core, improving misalignment tolerance.
- Rotary Head Data Storage Bulk Erasure Verification
Rotary head system merges write and read operations to perform bulk data erasure verification, eliminating separate access time losses.
- Optical Recording Apparatus Management Information Allocation
Dedicated management information record area prevents loss during power cutoff without increasing internal circuit complexity.
- Write-Once Disc Defect Management via TDMA and Access Indicator
Temporary defect management areas paired with an access indicator resolve initial access delays in write-once media.
- VCSEL EAMR Disk Drive Perpendicular Laser Alignment
Perpendicular VCSEL emission and grating coupling eliminate alignment sensitivity while stabilizing wavelength against temperature variations.
- HAMR Near-Field Transducer Gas Atmosphere Control
An oxidizing or reducing fill gas prevents carbon contamination and rhodium peg oxidation in a hermetically sealed HAMR enclosure.
- Transparent Overcoat Thickness for HAMR NFT Smear Prevention
A transparent overcoat layer minimizes the gap between the media-facing surface and magnetic media in a heat-assisted magnetic recording slider.
- Hybrid Plasmon Generator for TAMR Head Spot Size
A hybrid plasmon generator structure with a recessed noble metal layer and pegged non-noble metal core directs optical energy to the air bearing surface.
- RhIr Alloy NFT with Rh Template Layer for TAMR Reliability
A RhIr alloy near-field transducer uses a rhodium template layer to stabilize the microstructure and prevent oxidation defects in thermally assisted magnetic recording heads.
- Alloyed Plasmonic Antenna for Hardness in Magnetic Write Heads
Gold alloy antennas withstand ion milling and polishing, preventing particle embedding that degrades plasmonic heating performance.
- TAMR Heat Sink Bilayer Structure for Thermal Stability
A bilayer heat sink combines gold and ruthenium to dissipate plasmon heat while preventing noble metal migration at 450°C.
- Microwave Assisted Magnetic Head for High Density Recording
A microwave radiation waveguide generates an AC magnetic field to assist magnetization reversal in the recording gap.
