Abstract
A space for accommodating therein a portion of an optical pickup mechanism is arranged below a disk loading portion of a turn table member of a chucking mechanism of the present invention. The space is arranged axially below a disk mounting surface. Since such space is provided, a recording/reproducing portion will be allowed to move closer to a brushless motor, and therefore a second lens arranged further away from the brushless motor will be allowed to move radially inward of a recording/reproducing area of an optical disk.
