Abstract:
1. A disc device having a processing mechanism for executing recording or reproduction processing on a disc, the processing mechanism comprising: a control hoard on which a driver IC for driving a mechanism motor and a main control IC for executing main processing concerning the recording or reproduction processing on the disc are installed; and a SATA connector having a power supply unit and a signal unit, the SATA connector being connected to the driver IC and the main control IC and placed on the control board opposite the main control IC; wherein a pattern that connects the power supply unit to the driver IC and a pattern that connects the signal unit to the main control IC are formed on the control board; wherein the SATA connector and the main control IC are placed on the driver IC side with respect to a line passing through the center of the control board, the power supply unit is placed on the driver IC side, and the signal unit is placed on the main control IC side; and wherein in the control board, a voltage regulator and a flash memory are installed; the main control IC is placed at almost the center of the control board; the flash memory and the voltage regulator are placed on opposite sides with respect to the main control IC; and the driver IC is placed on the same side as the flash memory and at a position opposite the voltage regulator.
