    摘要: In one embodiment, a limited play optical storage medium for data can comprises a first substrate, a reflective layer, a data layer, a second substrate, and a reactive layer. The second substrate is a read-through substrate and is capable of transmitting less than about 10% of light in a wavelength in the range of about 455 nanometers and about 620 nanometers. The reactive layer can comprise a carrier and a reactive material. The reactive material can be capable of undergoing a reaction such that after the reaction a percent reflectivity through the reactive layer is reduced.

    摘要: In one embodiment, a multiwall sheet comprises: non-intersecting polymer walls comprising outer layers and transverse layers. The transverse layers intersect the walls to form cells. The multiwall sheet has a non-uniform cell density. In another embodiment, a multiwall sheet can comprise: non-intersecting polymer walls comprising outer layers and a transverse layer and/or a divider. The transverse layer and/or the divider extends from one of the polymer walls to another of the polymer walls to form cells. The multiwall sheet has a non-uniform cell density. In yet another embodiment, a multiwall sheet comprises: non-intersecting polymer walls comprising outer layers and transverse layers. The transverse layers intersect the walls to form cells. The multiwall sheet has a different number of inner layers, transverse layers, and/or dividers, in different portions of the sheet. The multiwall sheets can be used, for example, in a naturally light structure.
