Thank you. Super Metal Master The Super Metal Master cassette tape was released in September 1993 as the last top-of-the-line tape. The half is the same as the previous one, but the difference is the case. It evolved from a plastic case to a magnificent metal (aluminum) box. The price was high: 2,000 yen (excluding tax) for 46 minutes, 2,300 yen (excluding tax) for 60 minutes, and 2,600 yen (excluding tax) for 90 minutes. At that time, the running cost per minute of recording time was even more expensive compared to the DT-120 (120 minutes at standard mode recording, 1,600 yen excluding tax) blank tape for DAT released by the same company, and it was not an amount that could be easily used, further emphasizing a special sense of luxury and high sound quality.
