I-laser yokuqala Recordable diski; xa kwakukho yaye oko yasungulwa

Malunga nenkulungwane, ekubeni i-imi- 80 kwinkulungwane XIX, ngokuba umculo ekhaya iirekhodi ezisetyenziswa ukuba, nangona yokuphuculwa emininzi, hayi ngokuncamisayo yatshintsha.

uphawu Mechanical ukufunda ukususela kwingoma ezijikeleze yaba indlela engundoqo nokusebenza kwezixhobo ukuzala iminyaka engamashumi amaninzi. Yandile yaye zibuthe zosasazo, kwaye lale le ekhasethini, kodwa umthombo lokuqala uphawu ebhalwe kuzo ngokuqhelekileyo bakhonza iirekhodi acetate kunye IVinyl.

Le meko kuphela xa laser akwazi kuqala.

Xa yee- okuqala eSoviet Union, amarhe baqalisa ukuhamba lula ukuba West ngethuba abanye abadlali CD. Njani ukuba basebenze ngathi phantse akukho mntu waziyo. Abanye abantu ngqondweni ingakumbi enabileyo wacebisa ukuba endaweni yentloko eqhelekileyo ngenaliti kwi umdlali tonearm efakiweyo umthombo radiation olesayo umculo LP oluqhelekileyo. Abo baya kwamanye amazwe, Noomateloshe, oonozakuzaku kunye nezinye 'ukutyelela ", oko sele kusaziwa ukuba esi sixhobo emanyelwayo amalungiselelo ngokwahlukileyo.

Ekupheleni kwale yee- kweli lizwe waqalisa ukuzisa laserdisc yokuqala. Nini la "imimangaliso zobugcisa", baba imali eninzi kakhulu, yaye elula umculo lover ezazingekho ngalo. Amaninzi, bathenga abanini lwentsebenziswano "Studios recording" ukulungiselela iinjongo zorhwebo. Iinkqubo zomculo beluphindwe kunye IiBhalbhu Ngeekhasethi nomgangatho ibonwe unangoku.

Xa oku revolution technology irekhodi, nto leyo ingena irekhodi zikaJ eqhelekileyo weza laserdisc kuqala? Xa ubuchwepheshe wavela, ebavumela ukuba zivelise? kanye ingcamango optical ophethe inkcazelo leyo eqinisekisiwe ngo-1958 kwaye kuboniswe ikhadi umfundi ngenqindi amakhadi kunye ngenqindi. Lo mgaqo kulula. Ukuze ufumane, maza ukugcina nayiphi na imali iinkcukacha ezaneleyo ikhowudi yokubini kwi khowudi worse.

Kwisiqingatha sesibini 70s, iingxaki ezininzi zobugcisa, nto leyo yakhokelela sazimisela imbonakalo laser disc yokuqala. Umhla wokuqalisa yokuthengisa kwabo yobunzima - 1982 - nyangweni ukutshintshwa iirekhodi IVinyl kunye kwimarike irekhodi elo.

Njengazo naziphi na ezinye iinkcukacha, umculo ukuba enkhowudwa. Kulo mzekelo, ukuchana kwenziwe kuxhomekeke inyathelo quantization, ngoku ekuthiwa bitrate. Ekugqibeleni, ayanda umgangatho, kokukhona inani le bytes ezinikeziweyo uya umsindo ngendlela yedijithali. Ngokwalo mgaqo, SONY kunye nenkampani Philips waqalisa ukuphuhlisa laser akwazi kuqala. Xa kwakukho CD-DA (digital compact audio compact), yona omnye ngenjongo - ukurekhoda umculo.

Abathengi abazi zonke iinkcukacha yobugcisa, kuba umgangatho yabathengi ebalulekileyo imveliso entsha, yaye kuyamangalisa. Ukubanako ukudlala Inkqubo ozithandayo inani engenasiphelo amaxesha ngaphandle akukho kubola ngesandi, ubungakanani elincinane, Obusemagqabini ubunjani - zonke ezi iingenelo ezidityanisiweyo iipleyiti, inemibalabala inemibalabala.

Iingcali njengoko iimpawu zobugcisa uhlobo olutsha lwe eendaba ngokuncokola kakhulu. Capacity kwakunjalo ngoko 0.65 Gbytes, ukuze ngaloo ndlela yixina imizuzu 74 umculo ezikumgangatho kakhulu.

Ngoko nangoko wesuka ke ingcamango, njengoko ingasetyenziswa le idiski laser yokuqala. Xa ithuba ukubhala esephepheni, ingcamango ubuchwepheshe emazishicilelwe umqondiso yevidiyo. Kuqala umboniso, wakhululwa kwifomathi yevidiyo CD, waba Thriller odumileyo "emihlathini." Noko ke, ngokutsho izalathisi eziphambili umgangatho "umfanekiso" uhambelana malunga kwirekhodi sibubona ekukhanyeni format VHS kwi VHS, kodwa Ezantsi kunye Out izinto zaqala ...

Namhlanje lisetyenziswa jikelele laser idiski umthamo omkhulu, Digital Ezahlukeneyo Disc (DVD) kunye Blue Ray, kuquka multi-sixhobo sekhombuya esinee. Engaphezulu ekuphuculeni ukufundiswa kwe abathwali opto-digital na indlela ubugcisa FMD-ROM esekelwe kwi kwiipropati ezibengezelayo kumphezulu isimemezelo. Amandla IiCD enjalo ingaba 140 GB.
