摘要:
A component includes a micro-hologram layer, where the micro-hologram layer includes layers inert to light interleaved with layers of functional film. The functional film layers are made of a material that undergoes a change in its refractive index when illuminated by a light beam, yet undergoes no change in its refractive index when illuminated by a different light beam. The components may further include interleaved spacer films with multiple micro-hologram layers and other elements (e.g., servo layer, coatings, and the like) so as to comprise a data storage device. Methods of manufacturing the component and device are also disclosed.
摘要:
A data storage device includes a substrate layer, made of a moldable non-photopolymer plastic substrate and having a servo layer, adjoined to a stacked film structure that is constructed of multiple functional films, having data layers, with spacer film(s) disposed between each of the functional films. Methods of manufacturing the data storage device include using a roll-to-roll system to adhere thin spacer film extrusions between the multiple functional film extrusions so as to construct the stacked film structure. An additional method uses an application of functional film coating to thin spacer films and a roll-to-roll system.

Optical data storage media for bit-wise recording of a microhologram using an incident radiation at a wavelength of about 405 nm are provided. The optical storage medium includes (a) a non-photopolymer polymer matrix; (b) a non-linear sensitizer comprising a phenylethynyl platinum complex, wherein the non-linear sensitizer is capable of triplet-triplet energy transfer from an upper triplet state (Tn) of the non-linear sensitizer to a lower triplet state (T1) of a reactant, wherein “n” is an integer greater than 1; and (c) a reactant capable of undergoing a chemical change upon the triplet-triplet energy transfer from the non-linear sensitizer, thereby causing a refractive index change in the medium to record the microhologram.
