Abstract
A coil assembly for disk drive components is presented which includes a coil winding free of lubricants that cause stiction problems during the operation of the disk drive assembly. An actuator coil and spindle motor winding are disclosed which include a conductor, an insulating layer over the conductor, a bond coat overlying the insulating layer, and a lubricant coating on the insulating layer. The lubricant coating is a hydrocarbon based oil having a molecular weight within ranges that will not volatilize and condense on the surface of the disks in the drive.
