Hard disks and tapes

To meet the demand for increased storage density, the composition of hard disks and tapes has moved to thinner and thinner layered structures. Surface analysis techniques are ideally suited to characterize the nanometer protective coatings and magnetic layers that make up today’s magnetic media. In addition to characterizing the magnetic media, surface analysis equipment plays a key role in the development of read/write heads and the detection and characterization of contaminants on components throughout the disk drive.
