N2 - A herringbone groove pattern is applied to the plane disk damper of the hard disk drive to suppress axial vibration of the disk effectively. The design parameters of the herringbone groove such as mean radius rm, ridge-groove ratio B, and spiral angle β are studied numerically as well as experimentally. The stiffness and the damping coefficients are calculated using finite volume method and four-point central difference scheme. The axial vibration of the disk is measured when the plane and herringbone groove disk damper is used. It is found that a herringbone groove disk damper increases the stiffness as well as the damping coefficient of the air film up to 20%.
