Abstract
An optical recording/reproducing device which minimizes the number of home-in operations to move a pickup to a predetermined reference position of a disc, and a method of controlling the same. The optical recording/reproducing device includes a pickup to record or reproduce information on or from a disc, a pickup movement motor to move the pickup along the disc, a main power supply controller to detect whether power is initially supplied so as to output a home-in control signal, and a drive controller to perform a home-in operation, only when power is initially supplied according to the home-in control signal of the main power supply controller. Since the home-in operation is performed only when power is initially supplied, the number of home-in operations is minimized.
