PURPOSE: A brake disk structure is provided to reduce noise generated while operating a brake by reducing the axial or radial vibration of a disk brake through frictional force. CONSTITUTION: A brake disk structure comprises a disk hat, an outboard, an inboard(30), and a friction plate(200). The disk hat is connected to vehicle wheels and located in the center position of the structure. The outboard and the inboard are formed into plate shape and extended to the outside of the disk hat and faced with each other. The friction plate is mounted by a coupler to be adhered to the exterior of the inboard. The friction plate is composed of materials which is different from the materials of the inboard.
