ABSTRACT:
An optical disc device includes a first optomechanical mechanism, a second optomechanical mechanism, and a positioning mechanism. The first optomechanical mechanism is located under an optical disc insertable into the optical disc drive 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 drive to optically access a top surface of the optical disc. The positioning mechanism is to precisely locate the second optomechanical mechanism over the optical disc for optically accessing the top surface of the optical disc and to prevent the second optomechanical mechanism from interfering with movement of the optical disc during insertion and removal of the optical disc into and from the optical disc drive.
