AN 00120 - Measuring Diamond Like Carbon Films by Dispersive Raman Spectroscopy


Magnetic disk storage media are constantly driven to accommodate more data on smaller physical areas of material. To accomplish this, the area density must increase and the distance between the read/write head and the disk, also referred to as “flying height”, must decrease without catastrophic contact. In decreasing the flying height, it is important to apply a very thin protective coating to the disk, to minimize damage to the disk medium in the event of contact.
