Island record films; fabrication. |
摘要 |
<p>A novel optical data storage medium is contemplated, one apt for data-modulated writing with a laser beam (and reading with a non-erasing reading laser beam) of predetermined wavelength -- the embodiments thereof being characterized by an island-film information structure on multiple layers whose optical characteristics and thickness are chosen to accommodate a prescribed writing and reading energy and wavelength, whereby to provide an anti-reflection condition for unrecorded portions of the information film and a relatively higher reflectivity for recorded portions; the island configuration being adapted to be so affected by the contemplated write beam as to "agglomerate" and better transmit the read beam.</p> |
