As traditional data storage requirements move from 500 GB/platter technology to 1TB/platter technology, the data storage industry is moving from PMR (Perpendicular Media Recording) to HAMR (Heat Assisted Media Recording) and BPM (Bit Patterned Media).
These new platforms will most likely necessitate significant reductions in key areas such as glide height (height difference between the recording head and recording media) and flying height. Finer filtration ratings will then be required for such applications as nickel plating, substrate /media cleaning and lube coating.
