Apparatus For Flat Record Carriers TRIZ Cases
- Injection-Molded Hard Drive Cover With Metal-Reinforced Seal Flange
Embedded metal strips in the polymer flange prevent creep-driven seal pressure loss, keeping hard drives protected from dust and moisture.
- Embedded-Metal Base Plate for Helium Leak-Resistant Disk Drives
Insert-molded metal members reinforce the base plate wall, avoiding blow holes that can cause helium leakage in disk drives.
- Piezoelectric Electrode Slit Layout for Crack Detection
Capacitance-based inspection uses electrode slits to reveal cracks in piezoelectric elements, helping disk drive suspensions keep positioning accuracy.
- Dual Spindle Motor Control Using BEMF for HDD Power Management
Back-EMF-based control lets dual HDD spindle motors run disk stacks independently, cutting power use and peak spin-up demand.
- Dual Spindle Motor Control for Lower-Power Hard Disk Stacks
Independent spindle control uses BEMF feedback to run only active disk stacks, cutting power use and peak spin-up demand.
- Disk Drive Base Rib Structure for Airtight Circumferential Welding
A variable-width fixing rib creates a stable circumferential welding surface, preserving airtightness in larger-capacity disk drives.
- Hard Disk Drive Cover Welding for Thin-Wall Deformation Control
Friction-stir welding joins the HDD cover to the thicker base floor to limit thin-wall deformation while preserving helium sealing.
- Acid-Absorbing Form-In-Place Gasket for Corrosive Gas Sealing
Acid-absorbing fillers in a form-in-place gasket trap corrosive gases before they reach the enclosure and damage sensitive electronic components.
- Disk Drive Base Cover Structure for Airtight Welding
A rib with variable-width chamfers preserves welding area on thin sidewalls, keeping disk drives airtight while allowing larger disk diameters.
- Disk Drive Housing Laser Welding for Variable Rib Widths
Dual laser irradiation conditions stabilize cover-to-base welding around variable rib widths, improving disk drive housing airtightness.
- Disk Housing Wiring Board Layout for Helium Sealing and Disk Capacity
A recessed outer-surface wiring board and adhesive-filled through holes improve helium sealing while freeing internal space for more magnetic disks.
- HDD Suspension Geometry for Stable Tab Height on Loading Ramps
Optimized load beam distance ratios stabilize tab height, preventing ramp collisions and preserving reliable head loading in dense HDDs.
- Disk Drive Bottom-Wall Wiring Layout for Helium Sealing
An outer-surface wiring board and adhesive-filled recess seal motor lead through-holes, freeing internal height for more magnetic disks.
- PEM Electrolyzer Oxygen Generation in Helium-Sealed HAMR Drives
A PEM electrolyzer and hydrogen getter turn residual humidity into oxygen inside helium-sealed HAMR drives, limiting carbonaceous residue.
- Annular Spacer Geometry for HDD Disk Flatness Under Clamping
An inclined annular spacer offsets clamping deformation in multi-disk HDDs to preserve disk flatness and prevent flutter or ramp contact.
- HDD Ramp Protrusion Structure for High-Disk-Density Loading
Axially spaced ramp protrusions guide head gimbal loading, prevent interference, and support more magnetic disks without harder ramp manufacturing.
