Driving/Moving Recording Heads TRIZ Cases
- Vertically Translating HDD Ramp for Reduced-Head Disk Access
A lead-screw ramp elevator lets fewer HDD heads load across stacked disks, cutting cost while preserving active archival access.
- VCM Cross-Flux Magnet Assembly for Stronger HDD Air-Gap Fields
A cross-flux magnet inserted through a yoke opening forms a Halbach-like VCM assembly that boosts HDD air-gap flux with fewer parts.
- Ball Screw Cam Elevator With In-Pivot Stepper Motor for Reduced-Head HDDs
A multi-start ball screw cam with an in-pivot stepper motor moves HDD heads vertically across disk stacks while reducing head count, wear, and cost.
