Data Storage

ZYGO 3D optical profilers provide fast, precise, non-contact process metrology of hard disk drive components such as read-write heads and disks.

Read-Write Heads: Capabilities include characterization of magnetic thin-film heads, including pole-tip recession (PTR), air-bearing surface (ABS) flatness, and shallow-pad height.

Hard Disk Media: Measurement of disk platters for surface roughness, micro-waviness, and edge roll-off/dub-off.

Additionally, ZYGO laser interferometers can measure in-process disk platters, before intergration into finished drives. Software analysis assesses RVA characteristics of disks before polishing and applying coatings. Clamping stresses can also be analyzed by measuring flatness before and after disks are mounted to the hub.
