Summary
[edit]Description10cm empty tape reel, made in Belarus and Lithuania 02.jpg |
English: 10-centimeter (4 in) reels for magnetic audio tape, Soviet Union, made in Belarus (left) and Lithuania (right), Soviet Union. Late 1960s (the box had "28.4.1969" handwritten). Each holds 100 meters of regular-thickness tape.
Small-sized 10cm, 13cm, 15cm were common in the 1950s and the 1960s, when tape was expensive and tape speeds, accordingly, very low. Eventually, home taping market settled on much larger 18-cm / 550-meter reels. Русский: Десятисантиметровые катушки для магнитной ленты, производство (слева) Борисоглебского завода пластмассовых изделий БССР и (справа) Вильнюсской фабрики пластмассовых изделий (логотип PDG), не позднее 1969 года. Вмещают до 100 метров пленки. Мелкие катушки на 10, 13, 15 см использовались в 1950-е и 1960-е годы, когда пленка была дорога, а скорости её протяжки - малы. В 1970-е годы бытовая звукозапись твердо перешла на скорость 19 cм/с и 18-сантиметровые катушки. |
