TDK MA Type IV Cassette Tape

Type IV tapes use metal alloy particles rather than the iron oxide found in standard tapes. This formulation allows for significantly higher output, better high-frequency response, and a wider dynamic range, making it the gold standard for high-fidelity analog recording.

While it will physically fit in any standard cassette player, you need a deck that supports 'Metal' or 'Type IV' bias settings to get the intended sound quality. If your player doesn't have a specific Metal bias switch, it may not record or play back with the correct equalization.

Yes, to fit 110 minutes of tape into a standard cassette shell, the tape ribbon itself is thinner than that of a 60-minute cassette. While this allows for longer recording times, it requires a well-maintained tape deck to ensure smooth transport and prevent jamming.

Absolutely. The Type IV formulation is specifically designed to handle the wide dynamic range and high-frequency content of digital sources, making it one of the best options for capturing high-fidelity audio from CDs or digital files.

Factory-sealed means the original plastic wrap applied by the manufacturer is still intact, ensuring the tape has not been exposed to dust, moisture, or handling since it left the factory. It is the best way to ensure the tape surface remains in pristine condition.
