A disk device for improving a S/N ratio is provided with a spindle motor control substratearranged below a trayvia a buffer material and a medium substratearranged at a position different from the spindle motor control substratebelow the tray. The spindle motor control substrate, the medium substrateand the main control substrateof the device body are connected each other with a flexible print circuit (FPC). The medium substrateand a pickup headare connected with other FPC. The head detection signal is provided to the main control substratethrough the medium substrate. A driver IC for motor drive system is carried on the spindle motor control substrate.
