Patent ID: 7392530

Claim:
A disk drive system for clamping or holding a disk and for rotating the disk with a damper or holder, wherein the disk has an electronic function element and a first electrical conductive surface electrically connected to the electronic function element, the disk drive system comprising: a disk drive having at least one second electric conductive surface being arranged adjacent to a clamped or held portion of the disk and to be electrically connected with the first electrical conductive surface of the disk by pressure of the damper or holder; a first conversion means being connected with the at least one second electric conductive surface and disposed at the substantial center of the axis of rotation of the disk; and a second conversion means facing the first conversion means and disposed at the substantial center of the axis of rotation of the disk, at a stationary disk drive section, wherein signal transmission is facilitated between the electronic function element of the disk and the stationary disk drive section through the first electrical conductive surface of the disk, the at least one second electric conductive surface, the first conversion means, and the second conversion means.
