Abstract
In an optical information recording/reproducing apparatus which uses an actuator which can move a beam spot over the entire track area on a recording medium by supporting an objective lens for converging the beam spot on an optical disk by elastic members, the objective lens is located at the neutral position of the elastic members during a period other than the recording or reproduction operation of information, thereby reducing power consumption.
