  • USB interface-compatible computer peripheral unit
    Patent number: 6735648
    Abstract: Switching means has a first input section for receiving bus power through a USB interface and a second input section for receiving higher power than the bus power and can switch the power supply route from one of the input sections to the other. When power supply from the second input section is started, a CPU recognizes the power supply through detecting means and uses the switching means to switch the power supply route to the route for the second input section. This makes it possible to supply higher power, thereby increasing the rotating speed of a spindle motor to improve a data transfer rate.
