Mu 1928 i St. Paul, muri Minnesota, Richard Drew yavumbuye kaseti ya Scotch. Kaseti ishobora kugabanywamo ibice kaseti ikoresha ubushyuhe bwinshi, kaseti ifite impande ebyiri, kaseti yo gukingira ubushyuhe, kaseti yihariye, kaseti ifata umuvuduko, na kaseti ikata bitewe n'imikorere yayo. Imirimo itandukanye ikwiriye ibikenewe mu nganda zitandukanye. Ubuso bw'ikaseti butwikiriwe n'urwego rwa kole kugira ngo kaseti ifatanye n'ikintu. Kole ya mbere yaturutse ku nyamaswa n'ibimera. Mu kinyejana cya cumi n'icyenda, kaseti ni yo yari igice cy'ingenzi cy'ikole; muri iki gihe, polimeri zitandukanye zirakoreshwa cyane.
1. Ihame ryo gukoresha kaseti
Kaseti ifatana igizwe n'ibice bibiri: substrate na kole, bihuza ibintu bibiri cyangwa byinshi bitandukanyije binyuze mu gufatana. Ubuso bwayo butwikiriwe n'urwego rwa kole. Kole ya mbere yaturutse ku nyamaswa n'ibimera. Mu kinyejana cya cumi n'icyenda, karuboni ni yo yari igice cy'ingenzi cy'ikole; muri iki gihe, polima zitandukanye zirakoreshwa cyane. Kole zishobora gufatana ku bintu kuko molekile zazo zigirana isano na molekile z'ikintu kigomba guhuzwa, kandi iyi kole ishobora gufatana neza molekile. Imiterere ya kole, hakurikijwe ubwoko butandukanye, n'ubwoko butandukanye, hari polima zitandukanye.
2. Gushyira mu byiciro kaseti
Ibikoresho by'ibanze: bishobora kugabanywamo kaseti ya BOPP, kaseti y'imyenda, kaseti y'impapuro z'ubudodo, kaseti yo gupfuka, kaseti ya fibre, kaseti ya PVC, kaseti ya PE foam, nibindi.
Dukurikije uko ikoreshwa: ishobora kugabanywamo kaseti yo kuburira, kaseti yo ku tapi, kaseti y'amashanyarazi, kaseti yo gukingira impapuro, kaseti yo gupfunyika, kaseti yo gufunga, kaseti yo gufunga, kaseti ya module, nibindi.
Igipimo cy'uko isoko rigera ku isoko: gishobora kugabanywamo kaseti isanzwe n'ikaseti yihariye.
Dukurikije ubushyuhe bw'aho ikoreshwa: ishobora kugabanywamo kaseti y'ubushyuhe buke, kaseti y'ubushyuhe busanzwe, na kaseti y'ubushyuhe bwinshi.
Dukurikije uburyo bufatana: kaseti ifite uruhande rumwe n'ikaseti ifite uruhande rubiri.
3. Ibisobanuro bya kaseti
(1) Umuzingo mukuru w’umuzingo munini, ni ukuvuga kaseti y’icyitegererezo iri kuri mashini no kuyikuraho, ifite ubugari bwa metero 1 kugeza kuri metero 1.5, n’uburebure bwa metero amagana kugeza kuri kilometero nyinshi, bitewe n’imiterere itandukanye.
(2) Umuzingo w'inyongera ni umusaruro nyuma yo gusubira inyuma k'umuzingo mukuru, ubugari ntibuhinduka, kandi uburebure buratandukana bitewe n'ibisabwa (ubusanzwe metero 100, metero 50, metero 25, metero 10, metero 5, n'ibindi).
(3) Umuzingo wo gukata (umuzingo urangiye) ni ibicuruzwa biri ku isoko rusange.
