Read/write head

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.
