Scotch Dynarange - 1982 - US
Scotch / 3M were pioneers in magnetic tape, with their reel‑to‑reel formulations used in countless studios. Their cassette line dates back to the early days of the format, and by the 1980s they offered several ferric formulations across different price points.
Dynarange was part of Scotch’s higher‑grade ferric lineup, positioned above the BX and marketed as a “superior ferric” Type I. Although Scotch eventually shifted to re‑branding and outsourcing cassette production, this particular Dynarange is a USA‑made example from the period when 3M still produced its own shells and formulations.
Note 1: 90 Minutes: This tape is clean with no visible blemishes. What elevates it further is the original AAFES price sticker, a late‑1980s PX/BX military‑base retail label. These tapes were sold exclusively to service members and their families, and surviving sealed examples with intact AAFES stickers are uncommon, giving this tape a provenance that sits in a category of its own.. Only 1 available. (*)
(*) AAFES stores are Army & Air Force Exchange Service. They are a multi-channel retailer that provides quality merchandise and services to active duty, guard, reserve members, military retirees, worldwide, offering a one-stop shopping experience for service members.
About Scotch / 3M:
Five businessmen founded 3M in Two Harbors, Minnesota, in 1902.[7] Originally a mining venture, the goal was to mine corundum, but this failed because the mine's mineral holdings were anorthosite, which had no commercial value.[7] Co-founder John Dwan solicited funds in exchange for stock and Edgar Ober and Lucius Ordway took over the company in 1905.[7] The company moved to Duluth and began research and producing sandpaper products.[7] William L. McKnight, later a key executive, joined the company in 1907, and A. G. Bush joined in 1909.[7] 3M finally became financially stable in 1916 and was able to pay dividends.[7]
The company moved to St. Paul in 1910, where it remained for 52 years before outgrowing the campus and moving to its current headquarters at 3M Center in Maplewood, Minnesota in 1962.[8]
The company began by mining stone from quarries for use in grinding wheels. Struggling with quality and marketing of its products, management supported its workers to innovate and develop new products, which became its core business.[9] Twelve years after its inception, 3M developed its first exclusive product: Three-M-ite cloth. Other innovations in this era included masking tape, waterproof sandpaper, and Scotch brand tapes. By 1929, 3M had made its first moves toward international expansion by forming Durex to conduct business in Europe. The same year, the company's stock was first traded over the counter and in 1946 listed on the New York Stock Exchange (NYSE). The company is currently a component of the Dow Jones Industrial Average and of the S&P 500.
