Estimating the term…
A general optical storage system (OSS) contains an optical drive and a fluorescent multilayer disc (FMLD), which can be realized as a multilayer structure with data storage in fluorescent spots like pits or spiral grooves, divided by layers, transparent to reading and fluorescent radiation. The OSS includes a fluorescent signal reception device, capable of reading FMLD, as well as reflective CD and DVD discs (including CD-R, CD-RW, DVD-R, etc.). Increase of pit width in FMLD and use of microangle mirrors allow increase of the information signal. Elimination of FMLD fluorescence lifetime influence on data pulse duration allows an increase in the data reading rate. The absorption indices of different layers of FMLD are optimized.
A multilayer hybrid fluorescent optical disc having a top surface for receiving radiation for reading information from the disc, with the disc comprising a substrate having front and back sides, with a plurality of first layers having information-carrying surfaces successively located on the front side of the substrate, with the first layers being spatially divided by polymer layers and assembled together in a single unit with adhesive layers and with the substrate back side covered with a protective layer.
