ABSTRACT:
According to this invention, a recording/reproducing device includes a DC motor for driving cam plates in the horizontal direction, a sensor for detecting positions of the cam plates in the horizontal direction, and a horizontal cam groove portion which is formed on at least one end portion of the cam grooves and with which the cam pins of the pickup unit are brought into contact. The cam plates are driven in the horizontal direction by the DC motor, the cam pins of the pickup unit are brought into contact with the horizontal cam groove portion, and, at this time, initialization of the cam plates is performed by causing the sensor to detect the positions of the cam plates in the horizontal direction.
