Description
Oblast technikyTechnical field
Vynález se týká optického záznamového média 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 producing archive records by a laser beam comprising a substrate, a recording layer, a reflective layer and at least one protective layer.
Dosavadní stav technikyBACKGROUND OF THE INVENTION
Na optická záznamová média pro vytváření archivních záznamů jsou kladeny značné požadavky na trvalé zachování jejích reprodukčních vlastností, což vyžaduje jejich odolnost vůči nestandardním skladovacím podmínkám týkajícím se vzdušné vlhkosti, teploty a působení mikroorganismům. Tyto podmínky zpravidla nesplňují optická média obsahující jako záznamový materiál některá 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 větší tvorbou tepla v takto složené záznamové vrstvě a s problémy jeho šíření do dalších částí optického média. 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.The optical recording media for the creation of archival records is subject to considerable requirements for the permanent preservation of its reproductive properties, which requires their resistance to non-standard storage conditions relating to air humidity, temperature and exposure to microorganisms. As a rule, optical media containing certain dyes, such as cyanide dyes, does not meet these conditions. Increased attention is therefore paid to metal-based recording materials, which is, however, accompanied by more complex and demanding production technology and hence higher costs. The realization of the recording in the metal layer is associated with greater heat generation in such a composite recording layer and with problems of its propagation to other parts of the optical medium. At the same time, it can also cause distortion of the recording layer and distortion in reading the recorded data as well as undesirable changes in other layers, for example in layers adjacent to the top substrate.
Patent US 4 624 914 se týká optického média, jehož fotosenzitivní záznamová vrstva sestává z kompozitu obsahujícího přednostně Pd, O a Te respektive TeO2. Toto složení přináší zvýšenou záznamovou rychlost a odstup signálu od Šumu.U.S. Patent 4,624,914 relates to an optical medium whose photosensitive recording layer consists of a composite preferably comprising Pd, O and Te and TeO 2, respectively. This composition brings increased recording speed and signal-to-noise ratio.
Publikovaná přihláška US 2007/0104919 popisuje optický disk s několika záznamovými vrstvami, z nichž každá je tvořena dvěma reakčními vrstvami, přičemž jedna je složena ze SiN nebo SiN obsahující vodík a druhá obsahuje například Tb, La, Si, SiOn a vedle toho dvě okrajové dielektrické vrstvy.Published application US 2007/0104919 discloses an optical disc with several recording layers, each consisting of two reaction layers, one consisting of hydrogen containing SiN or SiN, and the other comprising, for example, Tb, La, Si, SiO n and two edge layers dielectric layers.
Publikovaná přihláška US 2009/0239022 je rovněž obdobně založena na přednostním použití kompozitu Te-O-Pd a kompozit Ag-Pd-Cu jako přilehlé reflexivní vrstvy. Zlepšených vlastností záznamové vrstvy se dociluje specifickým poměrem jednotlivých složek. /Panasonic/.The published application US 2009/0239022 is likewise based on the preferential use of the Te-O-Pd composite and the Ag-Pd-Cu composite as an adjacent reflective layer. Improved properties of the recording layer are achieved by the specific ratio of the individual components. / Panasonic /.
Publikovaná přihláška US 2010/0068444 popisuje záznamovou - datovou - vrstvu obsahující přednostně Te nebo jeho slitiny či kompozity s dalšími kovy. K záznamové vrstvě přiléhá uhlíková vrstva s infuzí plynu, přednostně CO nebo CO2- Alternativně je použita další uhlíková vrstva oddělená od první uhlíkové vrstvy kovovou vrstvou nebo dalšími vrstvami. Uvedené vrstvy jsou ohraničeny dvěma dieíektrickými vrstvami.Published application US 2010/0068444 discloses a data recording layer comprising preferably Te or its alloys or composites with other metals. Adjacent to the recording layer is a carbon layer with a gas infusion, preferably CO or CO 2. Alternatively, an additional carbon layer separated from the first carbon layer by a metal layer or layers is used. Said layers are bounded by two di-electric layers.
Výše zmíněné prameny představující nej novější dostupný stav techniky s návrhem různých řešení optických disků určených pro archivní účely. Jejich průmyslová realizace však nevylučuje možnost, že by některé z výše uvedených problémů spojených s vytvářením archivních disků přetrvávaly, nebo, že by byly aplikovatelné pouze při použití speciálních záznamových nebo čtecích zařízení.The aforementioned sources represent the latest available state of the art with the design of various optical disc solutions for archival purposes. However, their industrial implementation does not exclude the possibility that some of the above problems associated with the creation of archive discs persist or that they are applicable only when using special recording or reading devices.

Cestou k tomu, je navržení optimálního uspořádání a složení jednotlivých vrstev, které by eliminovalo vliv tepla vlhkosti a světla při vytváření záznamu a vliv dalších faktorů a podmínek při skladování jak prázdných, tak záznamy obsahujících nosičů informací. Součástí úlohy je také vytvořit médium, které by bylo možno použít pro záznam dat aSUMMARY OF THE INVENTION It is an object of the present invention to provide an easy-to-use, reliable, archival, optical recording medium with a maximum lifetime.

On the upper side, the disc 1 is closed by an upper substrate 12 also made of polycarbonate. resin.
Nad spodním substrátem 11 je nanesena ochranná vrstva 2 o celkové tloušťce přibližně 20 nm nazývaná též jako dielektrická vrstva, jejíž hlavní složkou je SiO2. Nad ochrannou vrstvou 2 jeAbove the bottom substrate 11 there is a protective layer 2 with a total thickness of approximately 20 nm, also referred to as a dielectric layer, the main component of which is SiO 2 . Above the protective layer 2 is
-2 CZ 302887 B6 mezi první a druhou kovovou vrstvou 31, 32 s reflexivními vlastnostmi a obsahujícími jako hlavní složku Cr vložena záznamová vrstva 3. První kovová vrstva 31 má tloušťku přibližně 4 nm s vyhovujícím rozsahem 3 až 6 nm. Tato vrstva slouží též jako stabilizační vrstva do doby před zápisem dat do záznamové vrstvy 3. Druhá kovová vrstva 32 má tloušťku přibližně 2 nm a s vyhovujícím rozsahem l až 3 nm. Vedle Cr mohou být pro kovovou vrstvu použity další prvky či jejich slitiny nebo sloučeniny jakojsou Ag, Al, Mg, Cu, Pd, Zn a podobné známé komponenty.Between the first and second reflective metal layers 31, 32 and comprising a recording layer 3 as the main component Cr, the first metal layer 31 has a thickness of approximately 4 nm with a suitable range of 3 to 6 nm. This layer also serves as a stabilizing layer until the data is written to the recording layer 3. The second metal layer 32 has a thickness of about 2 nm and a suitable range of 1 to 3 nm. In addition to Cr, other elements or their alloys or compounds such as Ag, Al, Mg, Cu, Pd, Zn and similar known components can be used for the metal layer.
Kromě stabilizujícího účinku má druhá kovová vrstva 32 funkci pomocného reflektoru pro čtení záznamu po provedení zápisu. Záznamová vrstva obsahuje slitinu TeSeBi a má tloušťku přibližně 10 nm a možným rozsahem 9 až 15 nm. Uvedené doplňující komponenty slitiny Te lze nahradit nebo dále kombinovat s dalšími prvky jako jsou Pd, O, Pb, Sn, Al, Cr, Co nebo směsi kovů a slitiny těchto komponent.

The first adhesive layer 61 and the second adhesive 62 have a thickness in the range of 3 to 25 nm and their main constituent is Si, alternatively carbon.
Z důvodu zvýšení odolnosti lze na vnější stranu spodního substrátu 11 nanést transparentní UV vytvrzovací lak o tloušťce přibližně 6 pm a vnější strana vrchního substrátu může být opatřena dvěma vrstvami bílého UV vytvrzovacího laku o celkové tloušťce 20 až 40 pm. V případě, že není vyžadován celoplošný popis vrchní strany horního substrátu 12, lze místo bílého vytvrzovacího laku použít rovněž transparentní UV lak.In order to increase the resistance, a transparent UV curing varnish of about 6 µm thickness can be applied to the outer side of the bottom substrate 11 and the outer side of the top substrate can be provided with two layers of white UV curing varnish with a total thickness of 20 to 40 µm. In the case where a full-area description of the top side of the top substrate 12 is not required, a transparent UV lacquer can also be used instead of the white curing lacquer.
Výroba disku 1 probíhala následovně. Na póly karbonátový disk o průměru 120 mm a opatřený vodicí drážkou představující spodní substrát U byla nejdříve ve vakuové komoře plasmaticky, v ochranné atmosféře naprášena ochranná vrstva 2. Naprášení bylo provedeno pomocí 3 katod, kde každá katoda naprašovaía vrstvu 6,5 nm Si reaktivní plasmou s O2, takže celková tloušťka dosáhla 20 nm. Na takto upravený spodní substrát l_l byly nejdříve v neutrální argonové atmosféře naprášena první koncová 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 CO2 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 manufacture of the disc 1 proceeded as follows. The carbonate disk 120 mm in diameter and provided with a guide groove representing the lower substrate U was first plasma-protected in a vacuum chamber, and a protective layer 2 was sputtered in a protective atmosphere. The sputtering was carried out using 3 cathodes, with O 2 so that the total thickness reached 20 nm. First treated end layer 31 made of Cr 3 nm thick was sputtered onto the treated substrate 11 in a neutral argon atmosphere, then a 10 nm TeSeBi recording layer 3 and a second 2 nm Cr metal layer 32 were also sputtered under argon atmosphere. . Subsequently, a main stabilizing layer 5 of boron with a thickness of 10 nm was formed by reactive plasma with CO 2 . Alternatively, instead of boron, C was sputtered with a reactive CO 2 plasma.
Pro spojení takto vytvořené spodní části disku 1 s vrchním substrátem 12 byla na stabilizační vrstvu naprášena v ochranné atmosféře plasmově první adhezivní vrstva 61 z SÍO2, a na spodní stranu vrchního substrátu 12 druhá adhezivní vrstva 62 z téhož materiálu. Alternativně byl v podstatě se stejným výsledkem použit samotný Si. Poté byly takto připravené dvě součásti disku slepeny k sobě UV vytvrdítelným lepidlem nastříknutím lepidla mezi adhezivní vrstvy obou rotujících disků a vytvrzením spoje UV lampou.For connecting the thus formed lower part of the disk 1 with the upper substrate 12 to be sputtered onto the stabilizing layer in a protective atmosphere by plasma from the first adhesive layer 61 of SiO 2, and the lower side of the top substrate 12 of the second adhesive layer 62 of the same material. Alternatively, Si alone was used with substantially the same result. Thereafter, the two disc components thus prepared were glued together by UV curable adhesive by spraying adhesive between the adhesive layers of both rotating discs and curing the joint with a UV lamp.
