Description
Optické záznamové mediumOptical recording medium
Oblast technikyField of technology
Vynález se týká optického záznamového me'dia pro vytváření archivních záznamů laserovým paprskem obsahujícího substrát, záznamovou vrstvu, reflexní vrstvu a nejméně jednu ochrannou vrstvu.The invention relates to an optical recording medium for creating archival records by a laser beam comprising a substrate, a recording layer, a reflective layer and at least one protective layer.
Dosavadní stav technikyState of the art
Na optická záznamová media pro vytváření archivních záznamů jsou kladeny značné požadavky na trvalé zachování jejich reprodukčních vlastností, což vyžaduje jejich odolnost vůči nestandardním skladovacím podmínkám týkajícím se vzdušné vlhkosti, teploty a působení mikroorganismům. Tyto podmínky zpravidla nesplňují optická me'dia obsahující jako záznamový materiál nektera barviva, například kyanidová barviva. Zvýšená pozornost je proto věnována záznamovým materiálům na bázi kovů, což je však provázeno složitější a náročnější výrobní technologií a tedy i vyššími náklady. Realizace záznamu v kovové vrstvě je spojeno s vetší tvorbou tepla v takto složené záznamové vrstvě a s problémy jeho šíření do dalších částí optického media. Zároveň může přivodit i deformace záznamové vrstvy a zkreslení při čtení zaznamenaných údajů i v důsledku nežádoucích změn v dalších vrstvách, například i ve vrstvách přiléhajících vrchnímu substrátu.Significant requirements are placed on optical recording media for the creation of archival records for the permanent preservation of their reproductive properties, which requires their resistance to non-standard storage conditions related to air humidity, temperature and exposure to microorganisms. These conditions are generally not met by optical media containing dyes, such as cyanide dyes, as recording material. Increased attention is therefore paid to metal-based recording materials, which, however, is accompanied by more complex and demanding production technology and thus higher costs. The realization of the recording in the metal layer is connected with the greater heat generation in the thus composed recording layer and with the problems of its propagation to other parts of the optical medium. At the same time, it can also cause deformation of the recording layer and distortion in reading the recorded data due to undesired changes in other layers, for example in the layers adjacent to the top substrate.

Z důvodu zvýšeni odolnost! lze na vnější stranu spodního substrátu H nanést transparentní UV vytvrzován lak o tloušťce pnbližné 6 pm a vnější strana vrchního substrátu může být opatřena dvěma vrstvami bílého UV vytvrzovacího laku o celkové tloušťce 20¾) pm. V pnpade, ze není vyžadován celoplošný popis vrchní strany horního substrátu 12, lze místo bílého vytvrzovacího laku použít rovněž transparentní UV lak.Due to increased durability! a transparent UV-curable lacquer with a thickness of approximately 6 μm can be applied to the outer side of the lower substrate H and the outer side of the upper substrate can be provided with two layers of white UV-curable lacquer with a total thickness of 20 .mu.m. In case a full-area description of the top side of the upper substrate 12 is not required, a transparent UV varnish can also be used instead of a white curing varnish.
Výroba disku 1 probíhala následovně. Na póly karbonátový disk o průměru 120 mm a opatřený vodící drážkou představující spodní substrát Π byla nejdříve ve vakuové komoře plasmaticky, v ochranné atmosféře naprášena ochranná vrstva 2. Naprášení bylo provedeno pomocí 3 katod, kde každá katoda naprašovala vrstvu 6,5 nm Si reaktivní plasmou s O2, takže celková tloušťka dosáhla 20 nm. Na takto upravený spodní substrát Η byla nejdříve v neutrální argonové atmosféře naprášena první kovová vrstva 31 vytvořená z Cr o tloušťce 3 nm, poté rovněž v argonové atmosféře záznamová vrstva 3 ve složení TeSeBi o tloušťce 10 nm a druhá kovová vrstva 32 z Cr o tloušťce 2 nm. Následně byla reaktivní plasmou s CO, vytvořena hlavní stabilizační vrstva 5 z boru o tloušťce 10 nm. V alternativním provedení byl místo boru naprášen C rovněž s reaktivní plasmou s CO2.The production of disk 1 proceeded as follows. A protective layer 2 was first sputtered on the poles with a carbonate disk with a diameter of 120 mm and provided with a guide groove representing the lower substrate ve in a vacuum chamber, in a protective atmosphere. with O 2 , so that the total thickness reached 20 nm. The first metal layer 31 formed of Cr with a thickness of 3 nm was first sputtered on the thus prepared lower substrate Η in a neutral argon atmosphere, then also in the argon atmosphere the recording layer 3 composed of TeSeBi with a thickness of 10 nm and the second metal layer 32 made of Cr with a thickness of 2 nm. nm. Subsequently, a main stabilizing layer 5 of boron with a thickness of 10 nm was formed by reactive plasma with CO. In an alternative embodiment, C was also sputtered with CO 2 reactive plasma instead of boron.
Pro spojent takto vytvořené spodní části disku 1 s vrchním substrátem 12 byla na stabilizační vrstvu naprášena v ochranné atmosféře plasmově první adhesivni vrstva 61 z SiO,, a na spodní stranu vrchního substrátu 12 druhá adhes.vní vrstva 62 z téhož matenálu. Alternativně byl v podstatě se stejným výsledkem použit samotný Si. Poté byly takto připravené dvě součásti disku slepeny k sobě UV vytvrditclným lepidlem nastříknutím lepidla mezi adhesivni vrstvy obou rotujících disků a vytvrzením spoje UV lampou.For the connection of the thus formed lower part of the disk 1 with the upper substrate 12, a first adhesive layer 61 of SiO 2 was plasma-sprayed on the stabilizing layer and a second adhesive layer 62 of the same material on the underside of the upper substrate 12. Alternatively, Si alone was used with essentially the same result. Then, the two components of the disk thus prepared were glued together with a UV-curable adhesive by spraying the adhesive between the adhesive layers of the two rotating disks and curing the joint with a UV lamp.
