Optical disc drive having two optomechanical mechanisms

An optical disc device comprising:

• first optomechanical means for optically accessing a bottom surface of an optical disc insertable into the optical disc device;
• second optomechanical means for optically accessing the top surface of the optical disc insertable into the optical disc device;
• positioning means for precisely locating the second optomechanical means over the optical disc for optically accessing the top surface of the optical disc and for preventing the second optomechanical means from interfering with movement of the optical disc during insertion and removal of the optical disc into and from the optical disc device;
• one of:
• one or more supports affixed to the first optomechanical means extending through one or more corresponding holes of a tray to push and rotate the second optomechanical means to a position over the optical disc at which the second optomechanical means 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 means is attached to rotate the second optomechanical means to the position over the optical disc at which the second optomechanical means is precisely located over the optical disc for optically accessing the top surface of the optical disc.

A method comprising:

• retracting a tray of an optical disc device into the optical disc device, an optical disc having been placed on the tray, the optical disc device having a first optomechanical mechanism to optically access a bottom surface of the optical disc and a second optomechanical mechanism to optically access a top surface of the optical disc;
• and,
• retraction of the tray into the optical disc device resulting in the second optomechanical mechanism rotating to a position at which the second optomechanical mechanism is precisely located over the optical disc for optically accessing the top surface of the optical disc,
• wherein retraction of the tray into the optical disc device resulting in the second optomechanical mechanism rotating to the position at which the second optomechanical mechanism is precisely located over the optical disc for optically accessing the top surface of the optical disc comprises one of:
• one or more supports affixed to the first optomechanical mechanism extending through one or more corresponding holes of the tray to push and 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;
• and,
• a spindle of the first optomechanical mechanism 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.
