Zadaj ostanki dvostranskega lepila - očitno bil na eni od Kiberpipinih razstav. [SLO]: Magnetni trak je bil pogosto uporabljeno shranjevalno sredstvo za računalnike od petdesetih do osemdesetih let 20. stoletja. Pred njegovo široko uporabo so bile glavni metode za shranjevanje in obdelavo podatkov luknjalni kartoni in papirni trakovi. Te zgodnejše tehnologije so bile omejene po zmogljivosti in težavne za ravnanje, kar je privedlo do prehoda na magnetni trak. Po obdobju magnetnega traku so postali glavne rešitve za shranjevanje trdi diski in SSD diski zaradi njihove večje hitrosti, zmogljivosti in zanesljivosti. Magnetni trakovi so bili običajno shranjeni v zaščitnih plastičnih kolutih, ki jih je bilo treba odstraniti, preden so trak lahko vstavili v bralnik trakov. Sam trak je bil tanek trak magnetnega materiala, prevlečenega na plastični film, običajno pol palca širok in navit okoli koluta. Kolut je lahko vseboval do 700 metrov traku, kar je omogočalo znatno shranjevanje podatkov v primerjavi s prejšnjimi metodami. Za uporabo magnetnega traku je operater namestil kolut na bralnik trakov in navoj traku vodil skozi vrsto vodil do navijalnega koluta. Ta postopek je zahteval previdno ravnanje, da se trak ne bi poškodoval. Ko je bil trak naložen, je bralnik trakov zaporedno bral ali pisal podatke, zaradi česar je bil magnetni trak idealen za obsežna, linearna shranjevalna opravila, kot so varnostne kopije in arhiviranje. [ENG]: Magnetic tape was a prevalent storage medium for computers from the 1950s through the 1980s. Before its widespread use, punched cards and paper tape were the primary methods for data storage and processing. These earlier technologies were limited in capacity and cumbersome in handling, prompting the shift to magnetic tape. Following the era of magnetic tape, hard disk drives and solid-state drives became the dominant storage solutions due to their increased speed, capacity, and reliability. Magnetic tapes were typically housed in a protective plastic reel, which had to be removed before the tape could be inserted into a tape drive. The tape itself was a thin strip of magnetic material coated on a plastic film, usually half an inch wide and wound around the reel. The reel could hold up to 2,400 feet of tape, allowing for substantial data storage compared to previous methods. To use a magnetic tape, an operator would mount the reel onto a tape drive and thread the end of the tape through a series of guides and onto a take-up reel. This process required careful handling to avoid damaging the tape. Once loaded, the tape drive would read or write data sequentially, making magnetic tape ideal for large, linear data storage tasks such as backups and archiving.
