Patent ID: 7933191

Claim:
An optical disc device comprising: a first optomechanical mechanism located under an optical disc insertable into the optical disc device to optically access a bottom surface of the optical disc; a second optomechanical mechanism located over the optical disc insertable into the optical disc device to optically access a top surface of the optical disc; a positioning mechanism 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 device; and, one of: one or more supports affixed to the first optomechanical mechanism extending through one or more corresponding holes of a tray to push and rotate the second optomechanical mechanism to a position over the optical disc at which the second optomechanical mechanism is precisely located over the optical disc for optically accessing the top surface of the optical disc; and, a spindle contacting a clamp to push a shaft to which the second optomechanical mechanism is attached to rotate the second optomechanical mechanism to the position over the optical disc at which the second optomechanical mechanism is precisely located over the optical disc for optically accessing the top surface of the optical disc.
