Optical disc device having two optomechanical mechanisms

摘要

An optical disc device has a first optomechanical mechanism, a second optomechanical mechanism, and a sled mechanism. The first optomechanical mechanism is located under an optical disc insertable into the optical disc device to optically access a bottom surface of the optical disc. The second optomechanical mechanism is located over the optical disc insertable into the optical disc device to optically access a top surface of the optical disc. The first and the second optomechanical mechanism are disposed on the sled mechanism. Movement of the sled mechanism results in both the first and the second optomechanical mechanism moving radially in relation to the optical disc.
