摘要:
When the USB power supply (VBUS) of the USB interface is used as the power supply for driving a conventional optical disc apparatus or disc apparatus, the supplied current exceeds the standard of USB. An optical disc apparatus is provided with: a spindle motor for rotating and driving an optical disc; a feed motor for shifting an optical pick-up in the direction of the radius of an optical disc, the optical pick-up carrying out either read-out of data that has been written in onto an optical disc or write-in of data onto an optical disc; and an actuator for minutely correcting the position of an object lens which is provided in the above described optical pick-up and which irradiates an optical disc with a laser beam which is collected, wherein a conversion circuit for changing a signal voltage of a servo processor, which is transmitted to a driving circuit of the above described spindle motor, is placed between the above described driving circuit and the above described servo processor for controlling the above described driving circuit along a signal line, and the above described conversion circuit can be controlled by a CPU provided in the above described optical disc apparatus.
