Surface Metrology in the field of Data Storage

Surface topography in data storage technology

Hard disk drives are everywhere, and everyone relies on them working reliably and perfectly. To guarantee these essential aspects, manufacturers and their suppliers devote significant energy to development and manufacturing.

Polytec gives them a helping hand in this regard. Whether you’re dealing with hard drive bearings, hard drive disks, or read/write heads, Polytec’s range of surface metrology products helps you boost reliability in your production processes.

Analyse read/write head of HDD — Capture the entire surface of a read/write head in a single pass. Reliable measurement of height differences of various components, flatness characterization, surface roughness, and more.

By measuring surface parameters, you can draw key conclusions for future production operations. This therefore allows you to examine the influence that flatness parameters have on bearing performance or reliably check defined tolerances in production.

Surface profilers for your metrology tasks

Micro Profiler

Micro.View profiler systems are optimized for measurements with sub-nanometer resolution. With focused optics and high vertical resolution they enable detailed analysis of microstructures, surface finish and material distribution where even the smallest deviations matter.

Macro Profiler

Pro.Surf inspects flatness, step height and parallelism on large parts and multi-part trays — non-contact, in seconds. No-crash telecentric optics measure even into bores, with the precision and repeatability production demands.

Roughness Tester

The Roughness Tester is our entry Micro.View system and the most cost effective way to get started into the 3D surface roughness measurement. Step from R to S parameters.
