Latest Patents

One of Parker's latest patents is for a magnetic recording disk file designed for contact recording. This innovative disk utilizes conventional disk technology while ensuring an extremely smooth top surface and high coercivity. The disk is incorporated into a contact recording disk file that requires a smooth head-disk interface. A superfinished untextured NiP coating on the disk substrate is oxidized to form a NiO film. This NiO film allows the subsequently sputter deposited magnetic layer to achieve much higher coercivity, making the disk suitable for contact recording applications. The NiO film and the later deposited layers conform to the smooth surface of the polished NiP, preserving the necessary smoothness for the head-disk interface. The preferred process for forming the NiO film involves annealing the substrate in air at a temperature that prevents the crystallization of the NiP film.
