Combination Recording TRIZ Cases
- Thermally Assisted Magnetic Head with Integrated Light Source and Waveguide
A thermally assisted magnetic head integrates a light source on a support substrate with a waveguide to guide light to the medium-facing surface.
- Variable Track Width HAMR Writing via Dynamic Laser Power Control
A heat-assisted magnetic recording head writes data tracks with variable widths by dynamically altering laser power levels during the writing process.
- Thermally Assisted Magnetic Head Record/Read Separate Protective Structure
A thermally assisted magnetic head uses a record/read separate protective structure to shield the recording area while preserving reading sensitivity.
- Disk Drive Fly Height Actuator Thermal Expansion Compensation
Dynamic fly height write profile adjusts actuator position based on periodic calibration measurements to maintain target spacing.
- Submount-Integrated Photodetector for HAMR Laser Alignment
Integrating a photodetector with the submount stabilizes laser power and alignment precision, resolving temperature-induced drift in HAMR heads.
- Multilayer Optical Disc Track Management for Layer Interference
A recording apparatus manages tracks across multiple layers to enable host recognition of disabled states.
- Recessed Main Pole HAMR Writer for Perpendicular Field Alignment
Recessing the main pole below the air-bearing surface separates optical and magnetic zones, resolving interference between components.
- Optical Disc Reading Device Laser Modulation Control
A reading device adjusts laser light modulation rate and average read power to maintain signal quality during high-speed data retrieval.
- Optical Disc Focus Detection via Signal Level Prediction
A focus detection system predicts signal levels to distinguish medium surface reflections from the signal surface.
- Extended Cavity VCSEL Bottom-Emission for Thermal Management
A monolithic extended cavity VCSEL emits light toward a slider substrate to provide optical power for thermally assisted magnetic recording.
