Abstract
A system for preventing the accumulation of excess lubrication in the form of lubricant lines on magnetic media disks for hard disk drives uses a mandrel design that produces negligible surface waves when the disks are dipped in lubricant baths. The mandrel has inverted tear drop shaped supports for the disks. The supports are smaller in overall size than an inner diameter hole formed in the disks and diminish the formation of waves in the lubricant bath.
