A semi-permanent enclosure for an optical data storage device (60) comprises a first film (50) dimensioned to overlie the read surface of device (60) and a second film (30) dimensioned to overlie the non-read surface. The enclosure includes rim means (20, 40) having an L-shaped cross section extending around the periphery of device (60). Film (50) may have optical couplant on the surface thereof destined for attachment to device (60) in use. The optical couplant preferably has a refractive index compatible with that of device (60) to minimise losses and distorsion of signals. Optical couplant may also be used with second film (30). The optical couplant may be a material capable of flowing into minor defects on the surface of device (60). This allows minor blemishes to be repaired so that stored data is not compromised. Alternatively, the optical couplant may be a solid malleable material interposed between device (60) and the film(s) or may comprise the film itself. |
