ABSTRACT:
An improved disk drive system using a non-ferrofluid conductive lubricant is disclosed. In the disk drive system, there is a plurality of critically spaced magnetic disks rotated by a disk motor. A spindle shaft, which is retained by the spindle sleeve, couples to the disk motor and to the plurality of magnetic disks for rotation. The spindle shaft and spindle sleeve uses a bearing, which is lubricated by a non-ferrofluid conductive lubricant. The lubricant is used to prevent electrostatic charge build up during operation of the disk drive system. The lubricant may be either a non-polar oil or a ball bearing grease and further comprising either a metal caged fullerenes compound, STADIS-450, ASA-3, or Polyfloe 130. One particular type of lubricant is an emeraldine salt of polyanilin produced according to the steps of first reacting a solution of HCL and ammonium persulfate into a solution of HCL and analine to form a polymer. Next, the polymer is mixed with ammonium hydroxide and then is prepared to have a molecular weight of 1,000-20,000. Finally, the polymer is mixed with dodecyl benzylsulfonc acid or camphor sulfonic acid until the emeraldine salt is formed.
