Latest Patents

Nagaral holds a patent for a "Conductive lubricant for magnetic disk drives." This invention presents an improved disk drive system that utilizes a non-ferrofluid conductive lubricant. The system features multiple critically spaced magnetic disks that are rotated by a disk motor. The spindle shaft, retained by the spindle sleeve, connects to the disk motor and the magnetic disks for rotation. The lubricant plays a crucial role in preventing electrostatic charge build-up during the operation of the disk drive system. The lubricant can be a non-polar oil or a ball bearing grease, and it may include compounds such as metal-caged fullerenes, STADIS-450, ASA-3, or Polyfloe 130. One specific type of lubricant developed by Nagaral is an emeraldine salt of polyaniline, created through a series of chemical reactions to achieve the desired molecular weight.
