    摘要: An optical data storage medium includes a triple layer recording structure (24) having an expan­sion layer (10), a retention layer (12) and a very thin reflective layer (28) interposed between the retention (12) and expansion (10) layers. The three layers are strongly bonded together so that the thermally and mechanically active expansion (10) and retention (12) layers can mechanically act upon each other through the intermediate reflective layer (28). The expansion (10) and retention (12) layers are dyed to selectively pass or absorb light of preselected wavelengths. The thin reflective layer (28) is adapted to partially pass and partially reflect light of preselected wavelengths.

    摘要: @ An erasable optical data storage medium including a substrate and a dual layer of a first material and a second material on the substrate. The dual layer is susceptible to expansion and contraction, to writing data thermally, to erasing data thermally and mechanically, and to reading data optically, the first material and the second material, respectively, being bonded together and remaining in the same physical state upon the expansion and relaxation of the dual layer. Methods and apparatus are also disclosed for recording data bits on the medium.
