If you're ordering an extra long cassette for duplication, you may be in need of c90 tape stock. c90 tape is what we use to load cassettes that are a total length of 74 to 90 minutes (37 to 45 minutes per side.) A little known secret in the cassette industry is that many retailers no longer carry c90 tape... but we still do! Duplication.ca is the place to go for your long player cassette releases!

These cassettes can be duplicated in high speed or real-time for that extra bump in quality and frequency range. The buck doesn't stop at c90, we can accommodate any cassette length up to 120 minutes (60 minutes per side.) That's two hours packed into one tape! We don't compromise quality for length, we still maintain a great frequency range (20Hz to 20kHz on real-time duplication) and duplicate as loud as possible while avoiding distortion and minimizing tape hiss.

The extra length cassettes are perfect for special releases such as B-sides and rarities compilations, collections of past EPs and singles, and double albums.

Our cassette duplication services come with free standard shipping to the United States and Canada. Check out our cassette duplication calculator for tons and tons of options on shell colours and packaging!
