Yintoni optical idiskhi yokugcina? CD-ROM drive, laser kunye nezinye akwazi optical

Ebomini bethu ngokuqinileyo thina iintlobo lweenkcukacha kunye nokugcinwa. Kwixesha elidlulileyo elikude zaprintwa logcino iphepha. Zeziphi eendaba mihla?

Optical drive: imbali yendalo

Isixhobo lokuqala ukugcina ezirekhodiweyo zaveliswa yi Sony umva ngo-1979. It uchazwa, njengokuba ngoku, disc yeplastiki umngxuma isetyhula embindini. Ekuqaleni ukuba isetyenziswe kuphela Ngokushicilela Iifayile zesandi, kunye nolwazi kuwo esisetyenziswe indlela ethile ikhowudi Pulse Code kwezwi. Ihlala into yokuba okubhaliweyo okanye isandi udlula analog-to-digital Converter kanye iguqulwe ibe iseti ziikhowudi.

Kamva, ngowe-1982, iJamani waqalisa ngobuninzi CD. Baya ukuthenga okugcina ezahlukeneyo lwefayile. Kungekudala, baba ezishelfini kuphela ilondoloza umculo.

nga amalungiselelo njani le CD? Iziseko esetyenziselwa lemveliso 1,2-ezinga- ubukhulu polycarbonate ipleyiti-120 mm ububanzi, nto leyo isale kuqala igqunyelelwe ngomaleko obhityileyo ngesinyithi (zegolide, aluminiyam, isilivere njalo njalo. D.), ke ngoko ivanishi. Loo lwazi lusetyenziswa metal ngohlobo kwemingxuma (izikhewu) extruded behamba endleleni zikhula. Ukufunda iifayile ezibhalwe kwi diski optical, Oku kwenzeka ngokusebenzisa umqadi ube mnye laser kunye ngamaza 780 NM. Oku kubonakala phezu kwipleyiti, iguqula lesigaba kunye nokuqina esiwa phezu kuloo mihadi. Uboleke kwakhona ngokuba izikhewu phakathi kuloo mihadi. Inyathelo track yomculo ibekwe kwi kweleli nama-1.6 microns.

Types of IiCD nabizayo

Kukho iintlobo ezininzi CD: compact disc (CD), Digital Ezahlukeneyo Disc (DVD), Blu-ray Disc (BD). Bonke babe nomthamo ezahlukeneyo kakhulu ukuba ubhale ingcaciso. Umzekelo, DVD-Recordable ziveliswa amandla ukusuka 4.3 ukuya 15.9 GB, kunye CD - 900 kuphela MB.

Kwakhona zizakubalulwa yokurekhoda idiski ubuninzi: elilodwa ezininzi. Xa imithombo efana emise ngokwahlukileyo isakhiwo uncedo kwemingxuma. ukurekhodwa ngaphezulu Kungumbulelo kunokwenzeka ukuba izinto eziphilayo phantsi amanyathelo lwe laser mnyama kunye notshintsho reflectivity. Xa parlance eqhelekileyo, le nkqubo ibizwa ngokuba ovuthayo.

Enye eendaba nabizayo ingahluka ifomu. CD ezimise (CD Waxonxa) ziya ezisetyenziswa kwishishini nokuzonwabisa nakubagcini iifayile ezirekhodiweyo neevidiyo. Baya kuza nayiphi imilo (isikwere, ekwimo-moya okanye nentliziyo). Sebenzisa ukuba CD-ROM drives akukhuthazwa ngenxa yokuba komsipha ngesantya esiphezulu.

CD-ROM kunye neentlobo zabo

Optical drive CD-R inaso lolwazi, nto leyo funda-kuphela. Bhala iifayile kuyo, ungenza kanye kuphela ngaphandle ilungelo ukuhlela isibuzi. Ekuqaleni umthamo kwezi idiski lafikelela MB 650 kuphela okanye imizuzu 74 odiyo. izixhobo ezikhoyo ngoku ukuba ungakwazi ukumelana ukuya ku-900 MB ulwazi. Izinto eziluncedo yokuba ukufunda luxhaswa yonke CD eqhelekileyo.

Xa inani elifanayo kwinkumbulo kwaye laser unalo CD-RW, kuphela iifayile kuyo, ungenza alobe amaxesha ezininzi (amaxesha ukuya ku-1000). Ukuze wenze oku, sebenzisa iinkqubo abasezantsi abaphathi be computer. Zisasuka kukuba asingawo onke izixhobo bakulungele ukusebenza kule fomati. CD-RW na kancinane imali eninzi ngaphezu CD-R.

CD equlethe umsindo neevidiyo ezirekhodiweyo musa unesinye iqondo ukhuselo, ukuba ukhutshelwe kwaza kwaveliswa. Kodwa zosasazo idatha ethile ukukhuselwa ikopi technology StarForce.

ROM compact ezibhalwe mveliso kwaye umva umdlalo kuphela data. Hlela le isithuthi akunakwenzeka. Kodwa isixhobo woqondo RAM-hlobo unako kwakhona ukuya ku amaxesha 10,000, kwaye baza bakhonza ukuya kwiminyaka engama-30. Ezi compact enzelwa neekhatriji ezongezelelweyo, ukufunda kwabo ayixhaswa yi drives eziqhelekileyo.

DVD-Nkwali kunye neempawu zazo

Digital Ezahlukeneyo Disc is a digital multi-njongo lokugcina. isakhiwo sayo luthe iqulethe ingcaciso eninzi (ukuya kwi-15 GB). Loo disk enombala kufana ethe kunye CD ezimbini. Ukugcinwa kunye nokufundwa ulwazi umthamo omkhulu kunokwenzeka ngokusebenzisa laser ebomvu, ngamaza yayo 650 NM kunye lens kunye imbobo eliphezulu lwamanani. DVD-compact disc kufuneka elinye okanye amabini Ngokushicilela icala, kwakunye enye okanye ezimbini maleko zomsebenzi kwicala ngalinye. Ezi zikhombisi ukugqiba amandla abo.

Njengoko nge CD-Recordable diski, DVD zahlulwe fomati eziliqela. DVD-R okanye iDVD + R inaso, apho kungenziwa kuphela abhalwe kanye ulwazi. phezu kwezi compact, umgangatho Ngokushicilela waphuhliswa Pioneer ngo-1997. "Thabatha" kunye nezixhobo "dibanisa" kwahluka imifanekiso maleko iingcinga kunye okhethekileyo zokumakisha.

Optical Akwazi DVD RW (DVD + RW, DVD-RW) banekhono eendaba CD. Yaye "dibanisa" eendaba likuvumela ukuba wenze utshintsho kwindawo obuyimfuneko imvo yakho. drives jikelele zinceda ukusombulula ingxaki ukungavumelani yeefomati (+ RW kunye -RW).

Yintoni-ray Player Blu disc?

Olu hlobo enombala drive ikuvumela ukugcina uze urekhodishe ulwazi digital kwi ezixineneyo. Kuba nezinye iinkcukacha (nokuba high definition video) usebenzisa blue laser umtha 405 NM, leyo linciphise kwingoma double spiral. Iifayile ukuba basondele kakhulu omnye komnye, ichaphazeleke kakhulu umonakalo, ngoko ukuze drive ukuba inkathalelo eyodwa. Kutshanje bokwenziwa izithuthi kunye ukutyabeka ekhethekileyo ukuba kupheliswa ngelaphu elomileyo njengesiqhelo.

Kukho compact Blu-ray ongasetynziswayo kunye ngebhegi zokurekhoda, kunye multi-maleko (maleko-2 ukuya kwi-4). Umthamo "laminate" umthuthi ifikelela 128GB. Ngaloo ndlela has standard enobubanzi cm-12. -Umaleko ezimbini standard Blu-ray Disc uphakamisa 50 GB of ulwazi. Kuphuhliso sisixhobo lifikelela umthamo 300-400 GB, apho unokufunda drives mihla. Kuba video zisetyenziswa kwi diski ubukhulu ezincinane (80 mm) kunye yokugcina umthamo we-15 GB.

Yokukhuseleka ikopi Blu-ray ezinamanzi yedijithali uphawula ROM-Marko kunye nobuchwepheshe olugunyazisiweyo Khuphela ephethwe.

Injongo MiniDVD-media

media Optical Mini DVD ikopi encinci i eqhelekileyo Digital Ezahlukeneyo Disc. Nguye 8 cm ububanzi yaye lisetyenziswa iikhamera kunye khamera. -Kabini idiskhi ongama ukuya ku 1.4 GB of data, ngokulandelelana, ndlela-mbini - 2.8 GB. Kwi le fomati ukuba MiniDVD-R (bhala kanye) kunye MiniDVD-RW (multiple).

Standard drive intshi-12 ayenzelwanga ukuba ukufunda Mini DVD. Xa usebenzisa compact ezinjalo kwi laptop emalifakwe yokuluka drive motor. Ngamanye amaxesha kukho iingxaki ekufundeni we yenethiwekhi ulwazi. Ngokuqhelekileyo kwiimeko ezinjalo, ikhompyutha ubonisa la magama "zafunyanwa umqhubi optical drive." Ukusombulula le ngxaki, iingcebiso Ndingumqondisi onamava.
