Posachedwapa, mauthenga awa ataya malo awo mozama chifukwa cha kuyambira kwachangu kwa maulendo apamwamba kwambiri okhudzana ndi chikumbukiro cha boma. Komabe, sizingatheke kuti tisiyane ndi ma disk. DVD yothandizira ndi yokwanira kusunga mapulogalamu ambiri ndi mafayili a multimedia. Ojambula amasonyeza kuti wogwiritsa ntchito alipo 4.7 GB. Zoonadi, kwa DVD, chidziwitso chodziwika bwino ndi 4.38 GB, chimene chikufotokozedwa ndi kusiyana kwa njira yowerengera. Lero tikambirana za teknoloji ya Digital Versatile Disc ndikumvetsetsa mndandanda wa ma TV.

Vuto ndi tanthauzo

Mawu akuti DVD, zodabwitsa, alibe kutanthauzira kosadziwika. Njirayi idapangidwa kuti ipange mawonekedwe a CD omwe ali ndi mphamvu, zomwe zimakhala zosakwanira. Poyamba, DVD yotanthauzira imatanthauza Digital Video Disc (Disc Video Disc). Komabe, kenako zinaonekeratu kuti simungathe kujambula mafilimu okha, komanso mafayilo ena. Ichi ndi chifukwa chake ena anayamba kutanthauzira tanthauzo lina, kumvetsetsa DVD Digital Versatile Disk. Kawirikawiri, zolemba zonsezo ndi zolondola.

Powonjezera voliyumu yomwe ilipo

Poyambirira izo zinatchulidwa kale kuti DVD-disks inalowetsa CD, omwe mphamvu zawo sizinali zokwanira. Kuti muwerenge deta yosindikizidwa pamwamba, mtengo wofiira wa laser uyenera kugwiritsidwa ntchito. Muzipangizo zothandizira izi zikugwiritsidwa ntchito chipangizo chapadera, chophatikizapo chigawo chowongolera komanso njira yowunika. Kusiyanitsa kwakukulu pakati pa denga lowala lomwe likugwiritsidwa ntchito powerenga ndi kulemba chidziwitso ndiloti ndilolumikizana, ndiko kuti, ndilokhazikika kwambiri. Izi zimapangitsa kuthetsa zotsatira za zovuta zotsutsana ndi kusokonezeka kwa kuwala. Pakukula kwa CD, ma radiator ochepa omwe analipo panthawiyo sankatha kupanga dothi lokwanira, kotero kuti kutalika kwazitsulo pazitsulo zazitsulo kunali pafupi ndi 1.6 μm. Pambuyo pake, miyezi yowunikira kwambiri yopangidwa ndi kuwala, inakhala yochepa kwambiri moti mbali yonseyo inachepetsedwa ndi theka. Kotero, mphamvu yowonetsera ya DVD-disk inakhala yochulukirapo kuposa ma CD. Kuphatikiza pa kuchuluka kwa njirayi, zinatheka kuthetsa mtunda pakati pawo, komanso kukula kwa maenje.

"Pie" kuchokera ku disk

Mphamvu ya DVD disc imatsimikiziridwa osati miyeso yomwe ili pamwambayi ndi kasinthidwe kwa mtanda wa laser. Zolankhulidwe zoterezi zinalengedwa , zomwe, zenizeni, zinagwirizanitsa ma disk angapo mumagetsi amodzi mwakamodzi pokhala ndi miyezo yofanana. Zolemba zambiri zoterezi zikhoza kuyerekezedwa ndi sangweji. Pogwiritsa ntchito, palibe njira imodzi kapena ziwiri yomwe imagwiritsidwa ntchito, koma imapezeka m'njira yoti phokoso la laser lowerenga liziyenda mwaulere pamtambo wapamwamba. Mau awo anafika pa GB 8.54. Mphamvu yamtundu wa DVD-diski, yomwe m'mimba mwake si 12, koma masentimita 8, ndi 5,32 GB. Mwachikhalidwe, galimotoyo ikhoza kukhala ndi ma radiator awiri, omwe amatsindika za kuya (pamwamba). Pali zitsanzo ndi boriti imodzi, yomwe imayendetsedwa ndi magetsi. Mphamvu zowonjezera za DVD zingakhale zazikulu kwambiri pakugwiritsa ntchito zotchedwa njira ziwiri. Kunja, ichi ndi chophweka, koma kujambula / kuwerenga ndi kotheka kuchokera kumbali ziwiri, zomwe zinkakhala zoyendetsa kwambiri kuti zitheke. Mphamvu ya DVD-ROM yachisinthidwe ichi imachokera ku 9.4 GB (awiri okhawo osanjikiza), mpaka 17.08 (zigawo zinayi, zolemba kuchokera mbali zonse ziwiri). Komabe, "pie" zoterozo sizinagwiritsidwe ntchito mochuluka chifukwa cha mtengo wapamwamba wogulitsa ndi kufunika kowachitira mosamala kwambiri, chifukwa pang'ono pang'onopang'ono zingachititse kuti n'zosatheka kuŵerenga deta kuchokera ku zigawo zakuya.

Kusunga zambiri

Pamtima ma disks a RAM amatha kugwiritsira ntchito luso la kutentha kwapansi ndi laser. Zolemba zawo ndizochita kupanga mapangidwe mu machitidwe omwe amawadziwika a FAT-32 ndikusankha mafayilo. Mwachikhalidwe, disks awa ali mu makapu apadera, omwe amachititsa kudalirika kwawo. Zikanema, ngati mutachotsa DVD-RAM kuchokera pazitseko, mungathe kugwira ntchito nayo pa galimoto yotchedwa Multi. Izi ndizo zothetsera zowonjezeka. Mphamvu zamakono za DVD za mtundu uwu ndi 1.46 GB (osagwirizanitsa umodzi, 8 masentimita) mpaka 9,4 GB (amodzi). Mawu akuti RAM amatanthawuza kuti kulembanso kumakhala kotheka. Chidulecho chingatembenuzidwe kuti "Kumbukirani ndi mwayi wopeza". Ndipotu, disk imeneyi imapangidwa kuti isungire deta ndipo izi zisanachitike, njira yothetsera mauthenga ena asanakwane. Makamaka ngati timaganizira nthawi yosungiramo deta (pafupifupi zaka 30) ndi chiwerengero cha zolembera zolemba (zoposa 100,000). Zopweteka ndizofika mtengo wapatali komanso kugawa kwapang'ono.

VideoCompacts

Njira zotsatirazi ndi DVD-Video. Ma disks awa adapangidwa kuti alembe ma multimedia stream. Imatchedwa "DVD-1 ... 18". Zoyamba zinayi zimasinthidwa ndi kuchepa kwake m'mimba mwake (masentimita 8 motsutsana ndi muyezo 12). Zithunzi zamakono ndi DVD-5, zomwe zingaganizidwe ndi 4.7 GB (imodzi yosanjikiza imodzi).

Chokhachokha ndi chokhazikapo mbali ziwiri, chifukwa chogwira ntchito yomwe ili yokwanira kutembenuza diski mu galimoto. Zovuta zawo ndi kusowa kwa malo a chizindikiro, kotero dzina limasonyezedwa pa gawo loonekera, pafupi ndi dzenje lalikulu.

Osakwatira kulemba

Maonekedwe a diski amayendetsa deta ya digito pa disks kunyumba agwirizanitsa ntchito yosungiramo zinthu komanso kupanga makanema enieni a kanema. DVD + -R yayamba kugulitsidwa popanda kujambula. Mwini wa galimoto yapadera akhoza kusunga pa diskiyi iliyonse yowonjezera kukhala mawonekedwe a digito. Mtunduwu ndi galasi-buluu, ndi kutuluka kwa violet m'dera la masewera. Dongosolo la DVD la mtundu umenewu ndilochokera ku 4.7 GB (umodzi umodzi kumbali imodzi) kufika pa GB.08 GB. Voliyumu imadalira, monga mwachizoloŵezi, pa chiwerengero cha zigawo ndi mbali. Komabe, chifukwa cha ndondomeko yabwino yamtengo wapatali, zovuta zowonjezera kwambiri ndi 4.7 GB. Poyambirira, kujambula kungatheke pokhapokha pothandizidwa ndi makina a kompyuta, tsopano mwayi uwu umakhala ndi osewera mavidiyo ambiri omwe angathe kusunga ma TV pa diski. Vuto loyanjana "-" ndi "+" R kalekale kalekale ndipo silingatchulidwe m'nkhaniyi.

Kulemba zambiri

Zovuta za mtundu wa disks wakale ndizowonekeratu - sangathe kulembedwa pochotsa deta. Kuti athetse vutoli, ma disks osiyana kwambiri, otchedwa DVD + -RW, adakonzedwa. Zitha kugwiritsidwa ntchito monga ngati nthawi zonse. Mawu akuti RW amaimira Zopindulitsa, mwachitsanzo, Zopindulitsa. Mphamvu ya ma DVD a m'kalasiyi ndi chimodzimodzi ndi "yosavuta" R. Komabe, zovala ziwiri ndizochepa kwambiri chifukwa chofunikira kugula galimoto yapadera yomwe ingagwire ntchito ndi disks. Kuonjezera apo, njira zowonjezeretsanso, ndikusowa kusamala mosamala, ndikumvetsetsa kwa mapangidwe awo amatanthauza kuti ndi disks izi zimayenera kuchotsa fumbi particles. Kuwombera kopanda phindu sikungakulole kuti muwerenge zambiri kuchokera m'munsimu. Motero, "classic" ndi dothi limodzi, limodzi limodzi. Mtundu wa pamwamba umasiyana ndi imvi mpaka pafupifupi wakuda. Chiwerengero cha zolembera zolembera ndizovomerezeka zikwi zikwi zingapo, koma pakuchita disk yotereyi silingalembedwe koposa 50-100. Ndipo pakapita nthawi kudalirika kwa kusungidwa kwa deta kumachepa. Motero, DVD-RW ndi yoyenera yosungirako deta komanso kusamutsa. Kulembetsa kungatheke ndi unit, mwachizolowezi. Panthawi imodzimodziyo, kugwiritsa ntchito mawindo a Windows, ndi kotheka kugwira ntchito ndi magalimoto onse (kuwerenga / kulemba mafayilo osasintha). Komabe, chifukwa chakuti muyezo wa ma discs omwe sungathe kulembedwa sungalole kuti apite patsogolo mofulumira, kawirikawiri ayenera kukhutira ndi maulendo anayi ofanana ndi 5.5 MB.

Chidule cha kujambula

Mphamvu yamakono ya DVD ikhoza kupitirira pang'ono. Izi zimapindula pogwiritsa ntchito gawo lotsogolera. Ntchito yowonongeka iyenera kuthandizidwa ndi chipangizo chomwecho. Ikhoza kukhazikitsidwa pa pulogalamu yotchuka ya Nero popita ku "Zosankha - Zambiri Zamalonda". Sitikulimbikitsani kugwiritsa ntchito chipangizochi pokhapokha ngati chiri chofunika kwambiri, popeza simungathe kuwerenga diskiyi pa galimoto yomwe simukudziwa momwe mungagwirire ntchito ndi Kugonjetsa.

Kodi bukuli likuwerengedwa motani?

Ambiri a makompyuta azindikira kwa nthawi yaitali kuti n'zosatheka kulembera CD kuchuluka kwa chidziwitso chowonetsedwa ndi wopanga. Ndipotu, palibe chinyengo pano. Omwe amapanga ma diski ku malingaliro akugulitsa amalingalira kuti mu 1 KB ma 1000 bytes, ngakhale mu chenicheni 1024 (ife timapanga chotsalira mu mphamvu ya khumi). Ndilikuwonjezeka, chiwerengero ichi chikukula patsogolo. Choncho, palibe kuposa "kukhulupirika" 4.38 GB omwe akuyikidwa pa DVD yovomerezeka.
