This patented technology can be used to create a NiP
electroless plated layer on any substrate without the
use of environmentally hazardous pre-plating solutions.
LN3 has numerous applications where a flat, smooth,
solderable, and bright surface is required on aluminum,
aluminum alloy, or aluminum-composite materials.
For hard disk drive applications a sputtered layer of a
special seed material is laid down on the disk
substrate. This seed layer provides a much
smoother layer for follow-on electroless plating of NiP
and thus results in a much smoother NiP coating.
As a consequence less grinding and polishing is required
to create a sputter ready substrate. Since
electroless NiP can be textured using conventional disk
texturing tools for longitudinal recording orientation
or for general tribology characteristics it can
transform any material such as glass, steel, etc. into
a substrate that can be prepared using conventional
aluminum blank finishing and texturing technology.
Since the LN3 technology provides planarization it can
reduce the requirements for substrate finish. The
net benefit of LN3 technology is:
- reduction of the cost of substrate preparation
- increase in production capacity with existing
- making available a wider selection of substrate
materials for hard disk drives
- extending the useful life of longitudinal
recording and allowing high density longitudinal
recording on glass disks and other materials
- allow for tribology texturing of perpendicular
recording media using conventional texturing
- reduce the creation of environmentally hazardous
