An optical disk drive with multiple optical pick-up heads is provided. The optical disk drive includes an upper cover, a base, a first carrier member, a second carrier member, a first limiting member, and a second limiting member. The base is disposed under the upper cover. The first carrier member disposed on the base and has a first optical pick-up head. The second carrier member is disposed on the upper cover and has a second optical pick-up head. The first limiting member is used for disposing the first end of the second carrier member on the upper cover. The second limiting member is used for disposing the second end of the second carrier member on the upper cover. The length of the first limiting member is larger than that of the second limiting member.

An optical element driving mechanism is disposed in an electronic device and configured to hold a plurality of optical elements. The optical element driving mechanism includes a plate, a base, a first holder, a second holder, and a biasing assembly. The plate is fixed to a casing of the electronic device. The first and second holders are individually configured to hold the optical elements and are disposed on the base. The biasing assembly connects to the plate and the base, and forces the base and the first and second holders to move relative to the plate.
