Capacity info DVD-ROM

Waxaa laga yaabaa in hadda ay tahay wax aan macquul aheyn in ay la kulmaan nin marnaba haysta lahaa CD ah. Recently, warbaahinta si dhab ah isku dhiibay ay sabab u hordhaca ah ee firfircoon ee drives more teknoolajiyada sare ku salaysan xasuusta adag-state. Si kastaba ha ahaatee, aan weli si buuxda u tanaasulaan cajaladood oo waa dhif talinayaa. awoodda DVD ku filan in ay ku kaydiso inta badan barnaamijyada iyo files multimedia.

Maanta waxaan la hadal oo ku saabsan technology Digital oo isu cajalid iyo Gudigga xisaabinta mugga ay warbaahinta ka qabtaan.

Dhibaatadu waxay la qeexitaan

DVD Ereyga, la yaab, ma laha kelmadaha ah dirayaan. Technology Tani ayaa la sameeyey si loo bedelo CDs caadiga CD, awoodda oo la sii kordheysa noqoto aan ku filnayn. Markii hore DVD u taagan tahay Digital Video cajalid (Digital Video cajalid). Si kastaba ha ahaatee, ka dib waxa caddaatay in ay macquul tahay in ay u qoraan movies ma aha oo kaliya, laakiin sidoo kale files kale. Tani waxa ay ahayd sababta in qaar ka mid ah ay bilaabeen in ay ku riday qaar ka mid ah macnaha ereyga, taasoo la micno ah disc DVD Digital oo isu (boosaska badan). Guud ahaan, labada waa decryption saxda ah.

By kordhinta cadadka la heli karo

Waxaa hore loo tilmaamay in DVD-cajaladood ayaa bedelay CD ah, taas oo aan awood ku filan. Si aad u akhriso xogta digital duubay dusha, waxaa lagama maarmaan ah in aad dalbato dogob laser khafiif ah. qalab The drive for this unit gaar ah la fuliyo, oo ka kooban radiating element iyo nidaamka diiradda. Farqiga ugu muhiimsan ee u dhexeeya dogobka iftiin loo isticmaalo xogta akhriska iyo qoraalka, waa in ay tahay isku xidhan, ka dibna waxaa jira waa mid aad u ciriiri ah diiradda. Tani waxay u ogolaaneysaa shiidaa tirtiro saamaynta ifafaale diffraction iyo faragelinta ee hirarka iftiinka. In koraya CD caadiga ah la heli karo waqti ka emitters Semiconductor Ghadafi ma ay awoodaan si ay u abuuraan dogob ku filan cidhiidhi ah, sidaas width ee tareenka on salka biraha disc a ahaa oo ku saabsan 1.6 microns. Ka dibna, dioska- light-emitting dheeraad ah oo casri ah ayaa lagu sameeyay horumar, dogobka kaas oo ahaa sidaas oo khafiif ah in width of track ahaa awoodaan si loo yareeyo by badh. Sidaas darteed, awoodda macluumaad ah ee DVD-ROM u ahaa dhowr jeer ka badan CD ugu dhimaya la mid ah. Sidoo kale width track ah, waxaa suurto gal ahayd in la beddelo therebetween fogaanshaha, iyo xajmiga ku tuurno.

"Cake" ee saxannada ah

Awoodda of a DVD-ROM waxaa lagu go'aamiyaa ma aha oo kaliya dhinacyada kor ku xusan iyo qaabeynta of dogob laser ah. sida abuuray warbaahinta, taas oo, dhab ahaantii, marka la isku daro saxannada badan hal wax soo saarka, iyadoo la sii dhinacyada caadiga ah. uwadida multi-lakabka noocan oo kale ah la rooti ah marka la barbar dhigo karo. In wax soo saarka la keligay ma isticmaalo, laakiin laba waddooyinkiisa, laakiin qorsheeyey si dogob laser reading soo gudubtaa si xor ah iyada oo dusha sare translucent top. Ay mugga gaadhay 8,54 GB. awoodda ugu badan oo ka mid ah DVD-disc, kuwaas oo dhexroor ma aha 12, iyo 8 cm, waa 5,32 GB. Qaab ahaan, drive waxay leeyihiin waxaa laga yaabaa in laba emitters, kuwaasoo mid walba uu diiradda saarayaa in ay si qoto dheer (dusha). Waxaa jira lagu daydo la dogob hal, taas oo maamusha ee korantada diiradda. Information awoodda DVD noqon kartaa weyn marka loo isticmaalo in xal laba-gobolka-ka loo yaqaan. Dibadda, waa CD si joogto ah, laakiin akhri / qortaa waa suurtogal labada dhinac, taas oo inta badan drives looga baahan yahay inuu ka soo leexdo gaariga. disc DVD-awood-habeynta sida waa ka 9.4 GB (hal-geesoodka ah lakabka) si ay u 17.08 (afar lakab, qoraalana labada dhinac). Si kastaba ha ahaatee, kuwaas oo "moofo" aan loo sabab u tahay qiimaha sare ee wax soo saarka iyo baahida loo qabo in aad ka taxadartaa in ay ula dhaqmaan sidii xoq ugu yar waxay keeni kartaa awood la'aanta in ay akhriyaan macluumaadka ka soo layers ku lammaan.

macluumaad xafidaada

technology The RAM-ku-saleysan disc been dusha diirinta dogob laser ah. Ay feature waa awood u leh inay qabtaan formatting ee la yaqaan nidaamka file xaydha-32, iyo eegista tirtirto files. Qaab ahaan, cajaladood, kuwaas oo waxaa la geeyaa gulufyadii gaar ah, taas oo kordhinaysa ay isku halaynta. Fikrad ahaan, haddii aad ka qaad, DVD-RAM ee jirka, waxa la shaqayn karin on drive a qoondeeyey sida Multi. Tani waa a xal caddaalad ah oo lagu kalsoonaan karo. Information DVD awoodda noocan ah waa ka 1.46 GB (hal dhinac hal-lakabka, 8 cm) si ay 9.4 GB (laba geesood ah). RAM waxa loola jeedaa in muqato waa jidh ahaan suurto gal ah. gaabinta loo tarjumi karaa sida "Random Access Memory". Dhab ahaantii, noocan ah disc waxaa loo isticmaalaa gurmad xogta iyo ka hor dhalashada of warbaahinta kale waa xal weyn. Gaar ahaan marka tilmaamay duration of kaydinta (30 sano) iyo tirada wareegyada overwrite (in ka badan 100 kun.). Khasaaro - kharash xad sare iyo faafinta hooseeyo.

Video ku

Go'aannada soo socda - waa DVD-Video. cajaladood waxaa loogu talagalay si ay u qoraan durdur multimedia ah. Loo yaqaan «DVD-1 ... 18".

Tan iyo markii ay ciyaartoyda video weyn isticmaali blocks diiradda fudud si loo yareeyo kharashka soo saarka, oo aan lagu daydo oo dhammu waa inay awoodaan inay akhriyaan xaddi weyn oo cajaladood. Marka laga reebo --hal daaha double-dhinac, taas oo keliya u baahan tahay inaad ku dhajisan disc ee drive ee. Ay khasaaro waa la'aanta ah ee meel qoraalka, sidaa darteed magaca waxa lagu tilmaamayaa qayb ka mid hufan, soo socota si ay godka dhexe.

Qor Marka

ah ee drives awood ugu leeyihiin qabashada qoro xogta digital in disc guriga, si ay u kacaan dhab berrinkii gurmad iyo maktabad filimka ugu dambeeya. DVD + -R asal ahaan ka iibiyey aan record. Milkiilaha of drive gaar ah badbaadin karo on disc ah macluumaad kasta oo si digital ah. towns muraayad-buluug Color gobolka buluug ah spectrum ah.

Weli, sababta oo ah sax ah siyaasadaha qiimaha ugu ballaaran loo isticmaalo ka hor uwadida fudud in 4.7 GB. Markii hore, waxa diiwaanka la samayn karaa oo keliya iyadoo la kaashanayo drives computer, laakiin hadda fursaddan si ay u leeyihiin ciyaaryahano badan oo video in lagu kaydin karaa on a drives gudbinta TV. "-" Dhibaatada of waafaqsan iyo «+» R muddo dheer ku hadhay ee la soo dhaafay iyo in article uusan kala hadli ma.

qoraal badan oo hoos

hore cillad disc nooca waa wax iska cad - ma ay dib-u-record karo, tirtirto xogta. Si loo xalliyo dhibaatada this ayaa soo jeediyay aasaas ahaan waa cajaladood oo kala duwan, loo yaqaan DVD + -RW. Waxay waxaa loo isticmaali karaa ku dhawaad sida drive a disk caadiga ah. RW waxa loola jeedaa Rewritable, i.e. rewritable. DVD Capacity of class this waa isku mid sida in ka mid ah "caadiga ah» R. Si kastaba ha ahaatee bilayer dhif kordhin sababta oo ah baahida loo qabo in si ay u bartaan drive gaar ah, si ay ula saxannada sida shaqeyn karin. Intaa waxaa dheer, ee xal rewritable iyo sidaas u baahan maaraysay si taxaddar leh isaga, iyo adayga ay design ka dhigan tahay in cajaladood, kuwaas oo si dhab ah u leeyihiin in ay afuufaan off Qurub ciidda. A xagashada random dushiisa ma awoodi karaan inay akhriyaan macluumaadka ka soo layers hoose. Sidaas darteed, "ayuu classic" - waa a-hal lakabka hal dhinac disc. midabka dusha kala duwan cawl in ay ku dhowaad madow. Tirada wareegyada u qortaa si rasmi ah uu ku saabsan yahay dhawr kun, laakiin dhab ahaan disc noocan oo kale ah, aad u qoraan kartaa ilaa 50-100 jeer. Oo markaas muddo halaynta kaydinta waa la dhimay. Sidaa darteed, DVD-RW ku haboon yihiin kaydinta muddo-gaaban iyo gaadiidka. Duubista unit noqon kartaa sidii caadiga ahayd. Isla mar ahaantaana la isticmaalayo hab Windows ayaa sidoo kale ka shaqayn kartaa sida drive caadi ah (akhri / qori files loo aabo yeelin). Si kastaba ha ahaatee, ay sabab u tahay xaqiiqada ah in disc caadiga rewritable ma ogola in la horumariyo xawaare sare, sida caadiga ah waxay leeyihiin si ay u degaan afar jeer, si siman u 5.5 MB.

duubo feature

The awoodda DVD caadiga ah waxaa laga yaabaa in wax yar ka sii badnayeen. Taana waxaa lagu gaarayaa iyada oo la isticmaalayo ee aaga hogaanka-baxay. function Overburn waa in ay taageerayaan qalabka.
