TDK D - 1986 - CA
"A great version of this "Benchmark" affordable Type I cassette. Legendary and reliable and this is the USA version. Honestly, the later and cheaper ones are just as good, but these are a bit rare now and great for nostalgia or collecting purposes. A big of negative bias and NR, and this is a very musical cassette." Tony Villa

Note 3: 90 Minutes: B-Grade: not really a B-Grade, but it is lightly scuffed with one (1mm) tiny rip (repaired). It's just not "box-fresh" like the others. See picture. Only 1 available

About TDK:
TDK’s origins trace back to 1935, when the Tokyo Denki Kagaku Kogyo company was founded to commercialize ferrite, a magnetic material invented by Dr. Takeshi Takei that would become central to modern recording technology. By the 1950s and 1960s, TDK had evolved from a materials science firm into one of Japan’s most important manufacturers of magnetic tape, supplying both industrial and consumer markets.
With the rise of the Compact Cassette, TDK quickly established itself as a global benchmark for tape quality. Their formulations, especially the AD (Normal), SA (CrO₂), and MA (pure metal particle) series, became reference tapes for consistency, durability, and performance. The SA and the MA lines near-legendary status among home recordists and audiophiles, helping define what "premium" cassette tape meant throughout the 1970s, 1980s, and 1990s.
TDK eventually sold its magnetic tape business to Imation in 2007. Today, TDK, is a major supplier worldwide of electronic components, sensors, and energy devices. Its strong focus on advanced materials and sectors such as EVs, renewables, and industrial automation, keeps it positioned as a top-tier technology company.
