Abstract
The invention provides a disc device capable of offering good SATA interface performance by optimizing the placement of the SATA connector relative to the control board, solving problems concerning noise or unnecessary radiation. A driver IC and DSP for executing main processing concerning disc recording or reproduction processing are installed in a main printed circuit board. A SATA connector having a power supply terminal and signal terminal is fixed to the main printed circuit board. The SATA connector is placed on the board opposite the DSP. Patterns each connecting the power supply terminal to the driver IC and connecting the signal terminal and DSP are formed on the board. The SATA connector and DSP are placed on the driver IC side relative to the central line of the board, the power supply terminal is placed on the driver IC side, and the signal terminal is placed on the DSP side.
