Disk device
A disk device for improving a S/N ratio is provided with a spindle motor control substrate 10 arranged below a tray 3 via a buffer material and a medium substrate 12 arranged at a position different from the spindle motor control substrate 10 below the tray 3. The spindle motor control substrate 10, the medium substrate 12 and the main control substrate 7 of the device body are connected each other with a flexible print circuit (FPC) 9. The medium substrate 12 and a pickup head 1c are connected with other FPC. The head detection signal is provided to the main control substrate 7 through the medium substrate 12. A driver IC for motor drive system is carried on the spindle motor control substrate 10. The motor drive signal is apart from the head detection signal and is provided to a spindle motor 1a or a head transferring motor.
