Scotch BX - 1990 - US
Scotch / 3M were pioneers in tape.
Their Reel To Reel tape was used in many a studio. Their cassettes were around from the early days too.
Then they realised that it was more economical to just re-brand their cassettes and have them made by someone else.
When you read about early Scotch cassettes, like their Highlander series, you hear stories of them going sticky as they degraded worse than contemporaries over they years.
Well, this isn't a Scotch made cassette. From what we can tell, it was made by Saehan, like many others at this time (Memorex, JVC, Mitsubishi...)
Not spectacular, use NR and negative bias and you'll be fine.
Two cases have a small crack and/or small wrapper blemishes.
About Scotch / 3M:
Five businessmen founded 3M in Two Harbors, Minnesota, in 1902. 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. Co-founder John Dwan solicited funds in exchange for stock and Edgar Ober and Lucius Ordway took over the company in 1905. The company moved to Duluth and began research and producing sandpaper products. William L. McKnight, later a key executive, joined the company in 1907, and A. G. Bush joined in 1909. 3M finally became financially stable in 1916 and was able to pay dividends.
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. 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.
