Surface Metrology
Data Storage
Hard disk drives are everywhere, and everyone is reliant on them working reliably and perfectly. To guarantee these essential aspects, manufacturers and their suppliers devote much of their energies 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 write / read heads, Polytec’s range of surface metrology products help you to boost reliability in your production processes.
Reliably Checking Hard Drive Bearings
Both the disk spindle’s and the actuator’s bearing on the read / write head plays a key role in hard disk drives. After all, only durable bearings make for continuous and reliable hard disk drive operation. Whether you’re at the stage of creating new bearing types in the development process, are further developing existing bearings or are carrying out random checks during production – by measuring surface parameters, you can draw key conclusions for future production operations. You can therefore examine the influence that flatness parameters have on bearing performance or reliably check defined tolerances in production.
Surface measurement systems from Polytec, and specifically the models in the TopMap range of products, are well suited to this application and can be tailored exactly to your requirements. Why not try our solutions out for yourself?

TopMap Metro.Lab
Being a complete measuring station, the TopMap Metro.Lab is ideally suited to large-area topographies on almost all surfaces. Since it offers great value for money, it is also attractive for smaller companies with fewer tasks.
TopMap In.Line
The TopMap In.Line’s compact design means it can be easily integrated into the production line and quickly carries out checks on differently reflective surfaces. Steps, larger ripples or other surface structures do not pose any problems here.
TopMap Pro.Surf®
Ideal for quick and precise 3D surface characterization. The areal measurement ensures that no details are overlooked. Short measuring times and a large field-of-view characterize the TopMap Pro.Surf®.
Contactlessly Monitoring Hard Disk Drives
The surface quality of hard disk drives is one of the deciding factors when it comes to reliable storage and retrieval of files and information – both for data processing centers and everyday personal use.
Polytec offers you suitable surface measurement systems for this very purpose You can use these systems to comply with specified tolerances, localize defects even on the production line and therefore analyze surface parameters quickly. The models in the TopMap range of products complete all of these tasks contactlessly, quickly and in a way that can be individually optimized to suit your application. Polytec’s solutions include microscope systems that you can use to detect even the smallest of details and large-area measuring systems with the same high level of height resolution for fast measurement of large surfaces.

Measuring the Surface Parameters of Write / Read Heads
A hard disk drive’s read/write head is an extremely complex component. Even at the development stage, it is important to check various surface parameters to make sure that everything will work perfectly later on.
Surface measurement systems from Polytec allow you to capture the entire surface of a read/write head in a single pass, so not only do you save time, but you can also reliably and easily analyze the height differences of various components. Flatness characterization doesn’t pose any problems either. Depending on requirements, you can use either large-area measuring systems or a microscope system to measure rough parameters.
