Abstract:
An enclosure for an optical data storage device having a read surface of a prescribed refractive index and a non-read surface, comprising:a first planar transparent film dimensioned to overlie the read surface of the optical data storage device;a second planar transparent film dimensioned to overlie the non-read surface of the optical data storage device,said first and second planar transparent films having a rim with an L-shaped cross-section and being dimensioned to extend around the periphery of the optical storage device; anda uniform layer of an optical couplant disposed on a side of said first planar transparent film to be applied to the read surface of the optical data storage device, for securing the first planar transparent film to the read surface of the optical data storage device and forming an optical interface between the first planar transparent film and the read surface of the optical data storage device, said optical interface having a refractive index differing by no more than .+-.10% from the prescribed refractive index of the read surface of the optical data storage device.
