Optical disc device and recording and reproduction methods of an optical disc device

A optical disc device of external attachment type connected to a computer via a USB port, comprising:

• a spindle motor that rotates an optical disc;
• an optical pickup unit that records information or reproducing information in the optical disc;
• a feed motor that roughly shifts the optical pickup unit in a radial direction of the optical disc;
• a spindle motor driver that drives the spindle motor;
• an actuator driver that drives the optical pickup unit;
• a feed motor driver that drives the feed motor;
• and
• a detector that detects a current from the USP port to the spindle motor, the actuator driver or the feed motor driver;
• wherein, when the detector detects that the current exceeds a pre-determined threshold, the optical disc device intermittently turns off one of the spindle motor driver, the actuator driver or the feed motor driver until the current reduces to a value below the threshold.
