Arm With Optical Waveguide TRIZ Cases
- Dual Bolometric Sensor for HAMR Laser Monitoring
A dual-function bolometric sensor detects laser power fluctuations and slider-medium contact using waste light absorption.
- Plasmonic Ceramic Near-Field Transducer for HAMR
A plasmonic ceramic near-field transducer concentrates light energy to generate localized heat for magnetic recording media.
- HAMR Drive Fault Detection for Data Integrity
Sensors monitor the energy source in HAMR drives to detect heating faults, triggering controller actions that protect data integrity against corruption.
- Asymmetric Magnetic Pole End Surface for Thermal-Assisted Recording
An asymmetric pole end surface adjusts the distance between a heating spot center and the magnetic pole in a thermal-assisted recording head.
- EAMR Head Plasmonic Plate for NFT Cooling
A plasmonic bulk metal plate cools the near-field transducer in an energy-assisted magnetic recording head.
- Laser Diode Temperature Control via Common-Mode Voltage
A laser diode heater uses common-mode voltage to steer temperature away from critical instability points.
- HAMR Head Middle Disk Thermal Stability
A middle disk with high melting temperature protects near-field emitter components from thermal degradation.
- Near-Field Transducer Recessed Region Thermal Gradient
A recessed region in the near-field transducer confines optical fields to enhance thermal gradients on the recording medium.
