A laminar piezoelectric element often applies to spin-stands and head testers for evaluate high-density magnetic recording because high speed positioning is needed for precise track follow with nanometer resolution and measurement of track profiles, and so on. However, since a magnetic recording head is easily damaged by electrostatic discharge, test environments of magnetic recording evaluations reach to humidity of over 60% to prevent the discharge. Therefore, inspection machines for the magnetic recording spin-stand are required to stand high humidity. However, the humidity of over 50% may cause migration to the laminar piezoelectric element of silver electrodes. We introduced a new sealed type of translational mechanism which can protect high humidity with linear motion effectively.
