Protective Coatings For Layers TRIZ Cases

A protective layer envelops protruding defects on magnetic tape to prevent electrical shorts and head wear.

Coating organic fluorine compounds on a protection layer creates a durable lubricant film for magnetic recording media.

Hydroxyl-modified perfluoropolyethers dissolve in water, eliminating fluorine solvent use and reducing environmental load while maintaining disk lubrication.

Oblique protective film deposition fills concave gaps between convex magnetic layers, reducing roughness differences and improving signal-to-noise ratios.

Segmented annular surfaces in a spindle motor connector recess confine uncured adhesive, preventing protrusion and gas leakage.
