Magnetic disks support the ubiquitous Internet society as an indispensable high tech product that is used in personal computers, car navigation systems, digital home appliances and other products. The levels of storage required for digital data is increasing all the time. Reading from and writing to disks is done with a magnetic head, and the distance between the head and disk surface is only a few nanometers. In order to improve storage density, this distance has gradually decreased year by year. Aluminum substrates are used mainly for desktop PCs and video recorders, while glass substrates are used mainly for notebook PCs. The great advances in storage density have been made possible by a fusion of leading-edge clean manufacturing processes and quality assurance systems, and the electroplating and ultra-precise fabrication technology that Toyo Kohan has developed. Our materials that achieve nano-level precision, and micron-level warping and flatness have been highly appreciated by customers in Japan and other countries.
