Optical Beam Sources TRIZ Cases
- HAMR Mode Hop Detection Using Reader Signal Envelope Feedback
Reader signal envelope detection identifies HAMR mode hops and adjusts laser current to keep media heating stable and reduce data loss.
- HAMR Laser Current Control for Mode Hop Heating Stability
Signal envelope detection from the reader adjusts HAMR laser current during mode hops to maintain media heating and data integrity.
- Hybrid Image Storage With Pixel Recesses for Digital Data
Pixel recesses encode grayscale or color by count and digital data by position, using one laser-based carrier structure.
