Abstract
An optical disk drive is provided. The optical disk drive includes a first carrying member disposed on a base, and a second carrying member disposed on an upper cover. The first carrying member has a first optical pick-up head and a spindle motor. The second carrying member has a second optical pick-up head and a clamper rotatably disposed on the second carrying member. The clamper and the spindle motor together clamp an optical disk.
