Driving/Moving Recording Heads TRIZ Cases
- Perpendicular Magnetic Tape Servo Writing
Dual-head biasing creates perpendicular servo marks on magnetic tape to resolve signal-to-noise ratio trade-offs.
- Magnetic Head Touchdown Detection via Staggered Actuator Control
A controller staggers touchdown detection across dual magnetic head actuators to enable precise flying height measurement.
- Sliding-Window Phase Gain DC Offset Estimation
Sliding-window estimators average discrete Fourier transform results across servo preambles to eliminate propagation delays in magnetic storage read channels.
- Tape Drive Control System Disturbance Compensation
A tape drive control system uses Youla-Kucera parameterization to adjust head position relative to the magnetic tape.
- Dual Spin Polarization Layer STO for MAMR AC Field Strength
Dual spin polarization layers orient field generation layer magnetization to increase AC magnetic field strength and signal-to-noise ratio.
