Disk Lubrication Equilibration System

      Disclosed is a system that controls the disk lubrication
thickness on thin film disks.

      The Disk Lubrication Equilibration System (DLES) is a series of
tanks, reservoirs and pumps that, in conjunction, make minute
measured adds to the dip lubrication bath.  As disks are dipped (60
disks per dip) in the bath, there is a thin film of lubrication
deposited on the surface.  Each time the process is repeated, the
bath becomes slightly more diluted.

      To eliminate the bath dilution, the DLES removes a few
milliliters of diluted bath and adds bath concentrate thru the
reservoirs and metering pumps.  By measuring the lubrication
thickness on the disks and fine tuning the metering pumps, the
lubrication thickness can be controlled to within two Angstroms.  The
lube process  is now operated within the statistical process control
limits.
