The Thickness Analysis of Oil Film on Hard Disk Surface

Hard disk has become very common in our daily life. To protect our important data, reduce the damage to the magnetic head when hard disk reading / writing the data, thickness of the lubrication oil on the disk surface plays an essential role in hard disk quality.

Photoemission Yield Spectroscopy in Air, short for PYSA (AC series), made by Riken Keiki, can assure the uniform thickness of oil from the energy change, according to the thickness difference of oil film on disk surface.
The measurement can be carried out in air and only takes 5 minutes.
For excellent quality and efficient development, we recommend our AC series.
