Abstract
In a recording disk drive apparatus including, a chassis including a chassis body, a spindle motor fixed to the chassis body to support and rotationally drive a recording disk, and a head supported on the chassis body to be movable on the chassis body in a radial direction of the recording disk so that an information is recorded into the recording disk and/or read from the recording disk through the head, a base member on which the chassis is supported, and an elastic member through which the chassis is supported on the base member so that a vibration transmitted from the chassis is absorbed at least partially by an elasticity of the elastic member, the chassis includes a counter member elastically supported on the chassis body with a spring constant for the counter member in which spring constant the counter member is elastically movable with respect to the chassis body.
