Mhlawumbe manje akunakwenzeka ukuhlangabezana ndoda yayingasoze ubambe CD. Muva nje, abezindaba sina umaluju izikhundla zabo ngenxa isingeniso asebenzayo of oshayelayo ngaphezulu yempucuko esekelwe kwimemori okuqinile-state. Noma kunjalo, okwamanje ukulahla ngokugcwele akwazi ukugcina kuhle neze. DVD umthamo kwanele ukugcina iningi izinhlelo namafayela multimedia. Abakhiqizi abonisa ukuthi umsebenzisi angasebenzisa 4.7 GB. Eqinisweni, i- DVD drive esiphezulu idatha nomthamo 4,38 GB, okuyinto zingachazwa ngezinqubo umehluko indlela yokubala. Namuhla sikhuluma Digital Anhlobonhlobo Disc ubuchwepheshe kanye ukubhekana ezicashile kubalwa umthamo abezindaba.

Inkinga nge izincazelo

I-DVD eside, okumangalisayo ayinayo emagama ngalokuvakalako. Lobu buchwepheshe zenzelwe esikhundleni CD ezivamile CD, amandla awo uya eba enganele. Ekuqaleni DVD imele Digital Isiqophi Disc (Digital Isiqophi Disc). Nokho, kamuva kwaba sobala ukuthi kungenzeka ukurekhoda hhayi kuphela ama-movie, kodwa futhi amanye amafayela. Lokhu kwaba ngenxa yokuthi abanye baye baqala ukubeka abanye incazelo ethemini, okusho DVD Digital Anhlobonhlobo (Anhlobonhlobo) Disc. Sekukonke, kokubili ukuqaqwa lesifanele.

Ngokwandisa inani etholakalayo

Sekuvele waveza ukuthi i-DVD akwazi ukugcina baye balisusa CD, okwakuyinto esanele. Ukuze ufunde baloba idatha digital kuya ebusweni, kubalulekile ukuba sisebenzise mncane laser ugongolo. Ukuhamba apharathasi kule yunithi ethize luyasetshenziswa, ehlanganisa imbuthuma isici futhi uhlelo ngokugxila. Umehluko omkhulu phakathi ugongolo ukukhanya esetshenziselwa idatha lizinga lekufundza nekubhala, wukuthi kuba anokuhambisana, khona-ke kuyinto esinda kakhulu igxile. Lokhu kuvumela cishe ongaqeda imiphumela ka umumo womsebenzi imihlola nokugxambukela ngamagagasi ukukhanya. Ekuthuthukiseni CD standard itholakala ngesikhathi ezincanyana Semiconductor emitters abakwazanga ukudala ugongolo ngokwanele ewumngcingo, ngakho ububanzi amathrekhi esisekelweni disc metal kwaba mayelana 1.6 microns. Ngemva kwalokho, eyinkimbinkimbi kakhudlwana diodes ukukhanya-likhipha zenzelwe, ugongolo okuyinto Wayezacile ukuze ububanzi ithrekhi wakwazi ukunciphisa ngesigamu. Ngakho, amandla ulwazi DVD-ROM kwaba izikhathi eziningana ephakeme ukwedlula efanayo ipharamitha CD. Futhi ububanzi ithrekhi, kwakunokwenzeka ukushintsha therebetween ibanga, kanye nobukhulu imigodi.

"Ikhekhe" we amadiski

Likhono DVD-ROM kunqunywa hhayi kuphela Ubukhulu ezibalwe ngenhla kanye ukucushwa kwe-ugongolo laser. Wadala enjalo abezindaba, okuyilokho, eqinisweni, kuhlangene amadiski amaningi umkhiqizo olulodwa, ebe egcina Ubukhulu ejwayelekile. Okunjalo multi-ungqimba umtselela wesikhatsi ingafaniswa sinkhwa. Esikhathini ukukhiqizwa alisetshenziswa sodwa, kodwa izindlela ezimbili, kodwa sihlelwe ngendlela yokuthi ugongolo Ukufundwa laser sihamba ngokukhululekile ngokusebenzisa ayevumela Ngaphezulu. umthamo wabo wafika 8,54 GB. Ngomthamo usuwonke DVD-disc, ogama ubukhulu akuyona 12, futhi abangu-8 cm, kuyinto 5,32 GB. Ikhipha idrayivu kungase kudingeke emitters ezimbili, ngayinye egxile ukujula yayo (ngaphandle). Kukhona onobuhle ugodo olulodwa, okusho ezilawula electronics ngokugxila. Imininingwane DVD umthamo kungaba nakakhulu lapho elisetshenziswa okuthiwa isixazululo ezimbili-state. Ngaphandle, it is a CD njalo, kodwa ukuthi ifunde / ibhale kungenzeka kusuka zombili, okuyinto iningi ngemoto edingekayo ukuze ujike imoto. DVD-umthamo disc ukuguqulwa enjalo ivela 9.4 GB (olulodwa ungqimba zamazwe amabili) ukuze 17.08 (izingqimba ezine, ukuqopha nhlangothi zombili). Nokho, lezi "amakhekhe" kungukuthi kabanzi ngenxa intengo ephakeme zokukhiqiza kanye nesidingo niqaphelisise sibaphathe njengoba ekuqaleni kancane kungaholela ukungakwazi ukufunda idatha kusuka izingqimba iyini imbangela yalokho.

Imininingwane esaziwa

I-RAM ezisekelwe disc ubuchwepheshe amanga Ukushisa kwamanzi ne ugodo laser. sici wabo nekhono ifomathi ajwayelekile uhlelo ifayela FAT-32, futhi ngokukhetha ususe amafayela. Ikhipha lezi akwazi ukugcina ezibekwe cartridges ekhethekile, okwandisa ukwethembeka. Kwakucatshangwa ukuthi uma ususa DVD-RAM yomzimba, bangasebenza nalo kwi drive eyabizwa ngokuthi i-Multi. Lena izixazululo sasivumela okuthembekile. Imininingwane umthamo DVD yalolu hlobo ivela 1.46 GB (olulodwa emaceleni olulodwa-ungqimba, 8 cm) ukuze 9.4 GB (zamazwe amabili). I-RAM nkulumo isho ukuthi ubhalwe kabusha kungenzeka emzimbeni. Isifushaniso esithi angahunyushwa ngokuthi "Finyelela okungahleliwe Memory". Empeleni, lolu hlobo disc isetshenziselwa isipele idatha futhi ngaphambi kokusungulwa kwe abezindaba okunye yisisombululo esikhulu. Ikakhulukazi lapho wagomela isikhathi yesitoreji (engaba ngu-30) futhi inani nowe ukubhala ngaphezulu (angaphezu kuka-100 eziyinkulungwane.). Ububi - izindleko kuqhathaniswa eliphezulu futhi ukusabalala ongaphakeme.

Video

Izinqumo ezilandelayo - kuyinto DVD-Video. Lezi akwazi ukugcina zenzelwe ukurekhoda ukusakaza multimedia. Ngokuthi «DVD-1 ... 18". Ezine zokuqala - ukuguqulwa kuyehla ububanzi (8 cm ngokumelene standard 12). zabuna Kubhekwe DVD-5, kusukela lapho kungase kubhekwe njengokwelapha 4.7 GB (olulodwa emaceleni). Ngakho, ngomthamo usuwonke DVD kulesi sigaba kuyinto 17,08 GB (DVD-18, emacala lamabili, izingqimba ezine). Kusukela omkhulu isiqophi abadlali zisebenzisa amabhlogo elula ngokugxila ukwehlisa izindleko zokukhiqiza, hhayi wonke amamodeli bayakwazi ukufunda semali akwazi ukugcina. Ukwehluka - olulodwa-ungqimba kabili emaceleni, okuyiwona badinga kuphela flip disc idrayivu. kusimo wabo ukuntuleka isikhala ilebula, ngakho igama kuboniswa phezu esobala ingxenye, eduze imbobo emaphakathi.

Bhala Kanye

Ukuvela ngemoto ongenza ukuqopha idatha sedijithali disc ekhaya, ukwenza revolution real emkhakheni isipele futhi wamanje kunazo umtapo ifilimu. DVD + -R ekuqaleni ithengiswe ngaphandle kwerekhodi. Umnikazi drive okhethekile ungagcina phezu disc yiluphi ulwazi computer. Umbala esibukweni blue tint nesifunda violet bohlu. Umthamo DVD yalolu hlobo ivela 4.7 GB (isendlalelo esisodwa ohlangothini olulodwa) ukuze 17,08 GB. Umqulu kuncike, njengenjwayelo, inani izingqimba nelayelo. Noma kunjalo, ngenxa efanele izinqubomgomo intengo kabanzi kunazo umtselela elula 4.7 GB. Ngaphambili, irekhodi eyayingenziwa kuphela ngosizo ngemoto computer, kodwa manje leli thuba Ziningi isiqophi abadlali ukuthi kungenziwa ligcinwa ngemoto yokudlulisela TV. "-" Inkinga ukuhambisana kanye «+» R isikhathi eside wahlala esikhathini esidlule futhi esihlokweni akusho ukuxoxa.

ngokubhala amaningi phansi

odlule uhlobo disc icala isobala - abakwazi urekhode kabusha, ukususa idatha. Ukuze uxazulule le nkinga okuphakanyiswe ngokuyisisekelo akwazi ukugcina ezahlukene, okuthiwa i-DVD + -RW. Zingasetshenziswa cishe like a disk drive evamile. I RW nkulumo isho ukuthi ebalisisiwe, isb elibhalekayo. Umthamo DVD alesi sigaba kuyafana ukuthi we "abavamile» R. Nokho bilayer akuvamile enwetshiwe ngenxa isidingo ukuthola drive okhethekile, ukwazi ukusebenza amadiski ezinjalo. Ngaphezu kwalokho, izixazululo elibhalekayo nokunye ezidinga handling ngokucophelela kuye, futhi eyinkimbinkimbi yendlela aklanywe ngayo kusho ukuthi lezi akwazi ukugcina empeleni babe ukushaya off uthuli. A imihuzuko okungahleliwe phezu abanakukwazi ukufunda ulwazi kusukela izingqimba engezansi. Ngakho, "zakudala" - kuba olulodwa-ungqimba disc eyodwa emaceleni. Umbala ebusweni kuhluka grey kuya cishe abamnyama. Isibalo bhala imijikelezo ngokusemthethweni imayelana eyizinkulungwane ezimbalwa, kodwa empeleni disc enjalo, ungakwazi alobe kuze kube izikhathi ezingamashumi 50-100. Bese ngokuhamba kwesikhathi isitoreji nokwethenjelwa sinciphile. Ngakho-ke, i-DVD-RW Site isitoreji yesikhathi esifushane neyezinto ezokuthutha. Ukuqopha iyunithi kungaba njengenjwayelo. Ngesikhathi esifanayo usebenzisa indlela Windows futhi ungasebenza njengomuntu drive evamile (funda / bhala amafayela ngokungenasizathu). Nokho, ngenxa yokuthi sithi indinganiso disc elibhalekayo ayikuvumeli ukuthuthukisa ngesivinini, ngokuvamile kufanele ulandele noma kane, ilingana 5.5 MB.

ukuqoshwa sici

Izinga DVD umthamo kungenzeka kancane kudlulwe. Lokhu kufezwa ngokusebenzisa phambili ukuphuma zone. umsebenzi Overburn kumele kusekelwa yidivayisi. Kungaba isebenze isofthiwe uNero ngokuya "Izinketho - Uchwepheshe izakhiwo". Asincomi usebenzisa lesi sici ngaphandle isidingo kakhulu, kusukela kungenzeka nobuso ukungakwazi ukufunda disc idrayivu, ayisebenzi nge Overburn.

Njengoba ivolumu ibalwa

Sekuyisikhathi eside abanikazi abaningi ikhompyutha ngaphawula ukuthi i-CD ayikwazi ukuqopha lemali kolwazi, okuboniswe ngumkhiqizi. Eqinisweni, akukho ukukopela lapha. Vele ushayele abakhiqizi ngezizathu ukumaketha bakholelwa ukuthi 1 kB 1000 bytes, kodwa eqinisweni e 1024 (yimani niqonde ezimbili ngezinga yeshumi). Nge ukwanda kwenani ukhula inchubekelembili. Ngakho-ke, indinganiso DVD-ROM ibekwe engasekho "ethembekile" 4,38 GB.
