Latest Patents

Kroeker's latest patents showcase his ingenuity in addressing key challenges in the hard disk drive industry. The first patent details a method and system for pre-contact detection and active damping of air bearing vibrations in a hard disk drive. This method involves isolating the slider from the ground and capacitively coupling it with a hard disk via a thermal fly-height control heating element. By applying an alternating current signal to the slider, Kroeker can effectively control its amplitude, improving the overall performance of the hard disk drive.

The second patent introduces an innovative disk drive system that employs a hydrodynamic bearing lubricant with charge-control additives, specifically dioctyldiphenylamine and its oligomers. This improved disk drive system features a magnetic disk that is rotatably mounted and operated by a rotor, which is coupled to the motor. The lubricant used in this system has a low relative electrical permittivity, enhancing the efficiency and reliability of the bearing interface.
