A device and a method to dampen the vibrations of a rotating disk in a data storage device, having at least one read/write device to read and write data onto and from the storage disk, and a drive unit including a stator and a rotor supporting the storage disk, whereby stator and rotor are set rotatable to each other by means of a bearing arrangement. One side of the storage disk forms a bearing surface which lies directly opposite a stationary bearing surface wherein at least one of the two bearing surfaces features a groove pattern which is formed in such a way that vibrations of the storage disk arising from its rotation are dampened or compensated.
