Reducing Carrier Contamination TRIZ Cases
- Friction Stir Welded Enclosure Joint With Bow Wave Recess
A recessed base sidewall absorbs excess cover material during friction stir welding, preventing bow wave defects and preserving hermetic enclosure seals.
- HDD Upstream Spoiler Top Fin for Top Disk Flow Mitigation
An overlapping top fin blocks rising airflow into the HDD top gap, reducing particulate contamination on the top disk surface.
- Magnetic Head Air-Bearing Island Blocker for Smear Mitigation
A hole and island blocker in the slider trailing pad redirects carbonaceous particles away from the recording head to limit smear.
- HAMR HDD Liquid Crystal Polymer Components for Low Outgassing
Water vapor and organic outgassing can contaminate HAMR heads; liquid crystal polymer components keep rates below 300 nanograms per gram.
- Fastener Seal System for Data Storage Device Contamination Control
A fastener seal system positions discrete seals at base cover apertures to enclose the data storage region and trap external contaminants.
- Segmented Front Bar Slider for Helium Particle Protection
Segmented front bars with multi-level recesses reduce recording medium scratches in helium environments without degrading dynamic performance.
- Disk Clamp Moat Design for Debris Trapping
A disk clamp features a central moat structure that traps debris particles generated during assembly.
- HDD Head Slider Particle Trapping Holes for Robustness
A head slider design featuring recessed particle trapping holes between leading pads to suction contaminants away from the media surface.
- Detachable Filter Unit for Hard Disk Drive Base
A holding frame secures a collection filter to the casing inner surface, preventing base deformation during maintenance.
