Ib feem ntawm ib qho kev sib cog lus muab cov duab kos duab sib tw thiab lub sijhawm rau cov tshaj tawm thiab cov tsim qauv.
kab hauv qab
Nyob rau hauv tsab xov xwm no peb nthuav tawm lub compact disc thiab tshuaj xyuas nws lub cev tsim tawm, piav qhia seb qhov sib txawv yuav cuam tshuam li cas rau koj lub compact disc tsim. Paub qhov nruab nrab koj tab tom tsim rau pab tiv thaiv kev xav tsis thoob hauv cov khoom kawg.
thaj chaw luam ntawv tseem ceeb
Lub ntsiab ntawm lub disc: Qhov no yog qhov chaw uas lub suab lossis cov ntaub ntawv raug encoded. Cov xim luam tawm ntawm qhov chaw no yuav zoo li tsaus dua li lawv xav tau ntawm daim ntawv dawb. Nyob ntawm tus cwj mem npog, qhov sib txawv ntawm cov nyiaj yuav pom los ntawm. Kev tiv thaiv tus number case ntau dua (xim tsaus, feem ntau) txhais tau tias koj yuav pom tsawg dua ntawm qhov pom ntawm qhov pom. Tsawg tus cwj mem npog, nrog cov ntawv luam tawm ntau qhov sib nrug (cov xim sib dua, feem ntau), yuav nthuav tawm ntau qhov hauv qab disc nto. Tib txoj kev uas yuav muaj ib yam dab tsi tshwm dawb nyob qhov twg ntawm lub compact disc nto yog sau nrog dawb number case.
kab hauv qab
Nov yog thaj tsam ntawm lub nplhaib sab hauv ntawm qhov chaw luam ntawv tseem ceeb. Daim iav band tsis tau encoded nrog cov ntaub ntawv yog li nws muaj qhov sib txawv ntawm qhov zoo, tshwm tsaus dua li lwm qhov ntawm lub compact disc. Feem ntau, daim iav band yog etched nrog lub npe ntawm cov chaw tsim khoom, nrog rau tus lej lossis tus lej barcode. Cov nyhuv ntawm kev luam ntawv ntawm daim iav band yog qhov tsaus nti ntawm cov ntawv nyeem lossis cov duab piv rau qhov chaw luam ntawv loj. Tsuas yog sab hauv ntawm daim iav band yog lub nplhaib stacking.
Txiv kab ntxwv
Nyob rau hauv qab ntawm txhua lub disc, lub nplhaib nyias ntawm cov yas tsaj yog siv los khaws qhov chaw me me ntawm txhua qhov disc thaum muab tso rau hauv lub thawv thiab / lossis xa khoom. Nws tiv thaiv qhov chaw tiaj tus los ntawm kev sib tsoo ntawm ib leeg, uas tuaj yeem khawb ntawm cov ntawv sau los yog cov ntawv nyeem tau hauv qab ntawm cov discs.
Txawm hais tias nws nyob rau hauv qab, qee cov tuam txhab lag luam tsis tuaj yeem luam tawm ntawm thaj chaw sib koom ua ke vim muaj "trough" me me tsim rau saum npoo thaum lawv pwm lawv cov discs. Lwm cov tuam txhab tsim pwm compact discs uas du rau saum thiab tsis muaj teeb meem luam ntawv hla lub nplhaib stacking.
Hub
Qhov no yog qhov innermost ntawm lub disc, ua los ntawm cov yas ntshiab, thiab suav nrog lub nplhaib stacking. Kev luam tawm ntawm thaj chaw hub zoo ib yam li cov txiaj ntsig ntawm kev luam ntawv ntawm kev tshaj tawm pob tshab. Qhov sib zog ntawm cov xim, qhov ntau dua qhov pom tseeb tshwm sim, vim yog qhov me me, dav dav cov duab luam tawm uas siv los tsim cov xim teeb.
Nrog rau cov number case hnyav dhau ntawm lub hub, qhov pom pom tsis tshua pom. Txawm li cas los xij, txhua yam xim yuav tshwm sim txawv thaum luam tawm ntawm lub hub yas zoo li piv rau lwm qhov chaw opaque ntawm lub compact disc.
Kev daws teeb meem rau qhov tsis sib xws
Kev siv lub tsho dawb lub hauv paus hla lub disc tag nrho cov ntawv luam tawm ua ntej luam tawm tus qauv tsim kom txo qis cov nyhuv tsaus ntawm daim iav band, thiab tseem txo qis qhov pom ntawm cov yas hub. Lub hauv paus dawb (qee zaum hu ua "dawb dej nyab") ua raws li lub tsho tiv no, yog li qhov kawg tsim zoo ib yam li luam tawm ntawm daim ntawv dawb ntawm cov txheej txheem pob zeb diamond, hnab nyiaj, ntawv, thiab lwm yam.
Yog tias koj tus qauv tsim cd suav nrog cov duab, tshwj xeeb yog ntsej muag, dej nyab dawb yuav ua rau lawv zoo dua qub. Nws tseem tuaj yeem pab kom phim cov xim uas siv rau ntawm cov ntawv sau. Feem ntau cov tuam txhab lag luam yuav tsis tuaj yeem hais qhia dej nyab dawb, thiab lawv tuaj yeem them nqi rau nws raws li lawv xav tau lwm tus cwj mem, tab sis nws tuaj yeem ua qhov sib txawv loj hauv qhov zoo li ntawm koj lub disc tsim.
Kev tshaj lij CD tsim muaj ntau dua li kev tswj cov duab, ntawv nyeem, thiab xim nrog cov khoos phis tawj: Txawm tias qhov zoo tshaj plaws uas tau xaiv hom ntawv yuav tsis sib txuas lus zoo yog tias pom qhov muag poob ntawm qhov sib txawv ntawm cov ntawv luam tawm; huab lossis daus ntawm tus qauv cd yuav dawb yog tias koj siv dawb ua ib qho ntawm koj cov xim luam tawm.
Cov yam ntxwv ntawm cov khoom uas koj tab tom tsim ua lub luag haujlwm tseem ceeb hauv kev tsim qauv tag nrho. Lub compact disc yog tsis muaj kev zam. Paub txog nws lub cev nqaij daim tawv pab txiav txim siab tsim qauv zoo dua thiab cov neeg tsim qauv zoo dua.
