Ama-discs wokuqala we-laser: lapho bekhona futhi ngalokho okwakhiwe

Cishe ikhulu leminyaka, kusukela kuma-80s ekhulwini le-XIX, ukulalela ekhaya umculo, amarekhodi egramophone asetshenzisiwe, okuyinto, naphezu kokuthuthukiswa okuningi, akuzange kushintshe ngokuyisisekelo.

Ukufundwa kwe-mechanical of the signal kusuka kwithrekhi yokuvunguza kwakuyindlela esemqoka yokusebenzisa amadivaysi okukhiqiza umsindo amashumi eminyaka. Ama-distributors amakhulu, ama-coil kanye nama-cassette ane-tape, kodwa umthombo oyinhloko wesignali oqoshwe kuwo ngokuvamile usebenza njengamarekhodi e-acetate nama-vinyl.

Isimo sashintsha kuphela lapho kuvela i-laser discs yokuqala.

Emashumini ayisishiyagalolunye e-Soviet Union baqala ukuzwa amahemuhemu ukuthi eNtshonalanga abanye abadlali be-laser. Yeka ukuthi basebenza kanjani, ngokuqinisekile, cishe akekho owaziyo. Abanye abantu abanomcabango onobudlova ikakhulukazi bacabanga ukuthi esikhundleni senhloko evamile ephethe inaliti emthonjeni wesibhamu somdlali kukhona umthombo wemisebe ofunda umculo ovela epulatifeni ejwayelekile yokudlala isikhathi eside. Labo abahambela kwelinye izwe, abalosi, abadibanisi kanye nezinye "ukuphuma", bekuvele kwaziwa ukuthi imishini yomsindo ehlelwe ngokuhlukile.

Ekupheleni kweminyaka engamashumi ayisishiyagalombili, i-laser discs yokuqala yayilethwe ezweni. Lapho lezi "zimangaliso zezobuchwepheshe" zivela, zazibiza kakhulu, futhi umculi omculo olula wayengatholakali. Ngokuvame ukuthengwa ngabanikazi bezinkampani zokubambisana "zokuqopha" ngenjongo yokuhweba. Izinhlelo zomculo zachazwa kusuka kubo kuma-CD-cassette enekhwalithi engakaze ibe khona.

Le mpuquko yenzeke nini ekubukisweni kwerekhodi yokulalelwayo, ngenxa yalokho i-laser discs yokuqala eyathatha indawo yokurekhoda irekhodi le-gramophone? Lapho kwakukhona ubuchwepheshe obuvumela ukuba kwenziwe? Umqondo we- carrier optical information wanikwa ilungelo lobunikazi ngo-1958 futhi wabonakala kumadivaysi okufunda amakhadi anenhlanhla namateyipu ahlaselwe. Isimiso silula. Ukuze uthole, uthumele futhi ugcine noma yimaphi amanani wedatha, kunamakhodi kanambambili okwanele , njengekhodi ye- Morse.

Phakathi nengxenye yesibili yama-1970, izinkinga eziningi zezobuchwepheshe zaxazululwa, okwaholela ekubukeni kwama-discs wokuqala e-laser. Usuku lokuqala kokudayiswa kwabo - 1982 - liphawu lokufaka amarekhodi e- vinyl emakethe yokuqopha umsindo.

Njenganoma yimuphi omunye ulwazi, umculo ukhonjisiwe. Kulesi simo, ukuthembeka kokukhiqiza kuncike kwisinyathelo sokuqagela, manje esibizwa ngezinga lentengo. Ekugcineni, ikhwalithi ephakeme, ama-bytes amaningi ohlelweni lwomsindo luzosebenza ngendlela yedijithali. Ngokusho kwalesi simiso, i-SONY ne-PHILIPS baqala ukuthuthukisa ama-discs wokuqala e-laser. Lapho i-CD-DA (ama-CD womculo we-digital) evele, ayehloselwe ngenjongo eyodwa - ukurekhoda umculo.

Abathengi babengayazi yonke imininingwane yobuchwepheshe, ngoba izimfanelo zabathengi bomkhiqizo omusha babalulekile, futhi bahlaba umxhwele. Ikhono lokudlala izinhlelo zabaculi bakho abathandayo inani elingapheli izikhathi ngaphandle kokuhlakulela umsindo, usayizi omncane, izinga elihle kakhulu - zonke lezi zinzuzo zihlangene kumapuleti, ukukhanya kwe-iridescent yama-iridescent.

Ochwepheshe bezimpawu ezifanayo zobuchwepheshe zohlu olusha lwababathwali bakhuluma okuningi. Umthamo wayo wawuyi-0.65 GB, eyanikeza umsindo womculo wamaminithi angu-74 ngekhwalithi elihle kakhulu.

Masinyane kwakukhona imibono mayelana nokuthi i-laser diss yokuqala ingasetshenziswa kanjani. Uma kunamathuba okubhala nge-audio, lo mbono wavela ngokusebenzisa ubuchwepheshe ukurekhoda isignali yevidiyo. Ifilimu yokuqala, ekhishwe ngefomethi yeCD Video, yayiyi-thriller edumile "Jaws". Yiqiniso, ngenxa yezinkomba ezinkulu zekhwalithi, "isithombe" cishe sihambelana nokurekhoda kwamagnetic kwifomethi yeVHS kuma-cassette evidiyo, kodwa inkinga iqala ...

Namhlanje ama-laser diss of capacity ephakeme kakhulu, i-Digital Versatile Disc (DVD) ne-Blue Ray, kufaka phakathi ama-multi-layer, asetshenziswa kabanzi. Ukuthuthukiswa okuqhubekayo kwemithombo ye-optical-digital kuhamba phambili ekuthuthukiseni ubuchwepheshe be-FMD-ROM, esekelwe ezindaweni ezifakiwe ezifakiwe. Amandla alawo disks angafinyelela ku-140 GB.
