Our ceramic substrates, made of alumina and titanium carbide and polished using advanced techniques, are widely used to make thin- film magnetic heads for computer hard disk drives. These substrates must not only have smooth surfaces and be free of residual strain, but must also possess the various properties needed to assure proper operation of the hard disk drive, especially resistance to wear caused by the magnetic storage medium.
The superior quality and performance of our ceramic substrates for thin-film magnetic heads have made them the world's top sellers.
