★Unopened Pair★TDK MA Metal★IV position★54 minutes★Metal Cassette Tape★Made in Japan 1992〜For collection/completion Contents: ・Several deadstock items from that time are being released. Listing is for a pair of 2. MA 54, released in 1991, is listed separately. This is the product line before the silver one. It was followed by the gold design-based one, which is also listed separately. I recommend the new package, but these are, as expected from TDK, and based on my experience using them, they don't degrade at all even when overwritten. As expected, TDK. I had been using a tape recorder since before I started elementary school (when ferric chrome was the best), and wanting to record in good sound, I thought that expensive tapes would produce good sound, so I bought SONY's DUAD with all my allowance in first grade. Eventually, I realized much later that the quality from the source to the tape was important, but I didn't know the ferric chrome position, and metal tapes hadn't even been released yet. While playing around recording things on my mother's tape recorder, the engineer uncles who were her colleagues said that TDK was good... and I started using TDK. That was the era with the diamond design. Walkmans didn't exist yet, and we naturally listened to music recorded on tape recorders both outside and inside. Because of that, TDK holds a special place in my heart. TDK was a company that enjoyed top-level global recognition during a time when Japanese products were striving to catch up and surpass overseas evaluations. The final masterpieces of such a company are around this era. Of course, they also released superior metal and high-position models, which were standard for cassette deck manufacturers. I couldn't accept how the piano sound faded away, and I probably bothered the technicians by saying all sorts of things as a kid, but perhaps they couldn't stand the noisy kid anymore, and they secretly told me the standard tape for that manufacturer. Even so, the resonance and lingering sound of the piano were difficult. TDK maniacs probably already have complete collections, so I hope that those who don't will find these after they've been listed for a while, after the bargain shops have bought them up and sold them all online. May those who find them then be blessed.
