Abstract
There is provided a disc drive adopting a slot-in loading by which an optical disc (2) is loaded into or ejected out of the device body through a disc slot. The disc drive can have loaded therein a large-diameter optical disc (2A) and small-diameter optical disc (2B), different in outside diameter from each other. With the small-diameter optical disc being set on a turn-table (23a), an objective lens (25a) is retreated in a direction away from the signal recording surface of the small-diameter optical disc when a pickup moving mechanism (26) moves an optical pickup (25) between the outer and inner radii of the small-diameter optical disc.
