AI Technical Summary

Problems solved by technology

Specifically, polishing slurries have a tendency to bond to the surface of the disk making removal of contaminant particles from the slurry difficult
If contaminant particles are not removed from the surface of the electropolished disk, the operation and performance of hard disk drives including the disk may be negatively affected

Abstract

A method for cleaning plated polished disks used in hard drive media is provided. The method includes positioning plated polished disks in a first batch scrubber having multiple first brushes, wherein each of the plated polished disks is positioned between two of the first brushes, and scrubbing the plated polished disks with the first brushes. The method further includes positioning the plated polished disks scrubbed in the first batch scrubber in a second batch scrubber having multiple second brushes, wherein each of the plated polished disks is positioned between two of the second brushes, and scrubbing the plated polished disks with the second brushes.

Description

technical field [0001] The present disclosure generally relates to a cleaning process used during the manufacture of magnetic disks for use in hard drive media, and more particularly to a cleaning process used after polishing plated magnetic disks. Background technique [0002] Magnetic disks used in hard drive media include substrates plated with materials such as nickel. The plated disks are then polished using chemical mechanical polishing. The surfaces of the magnetic disks are exposed to contaminants from polishing slurries, polishing residues, manufacturing equipment, and the manufacturing environment. In particular, polishing slurries have a tendency to bond to the surface of the disk making removal of contaminant particles from the slurry difficult. If the contaminant particles are not removed from the surface of the plated polished disk, the operation and performance of the hard disk drive including the disk may be negatively affected.
