Calibration tapes

This is it.
You have found calibration tapes for your Nakamichi deck.

You think your tape deck is misaligned. But you are not too sure. You need a reference, but can’t get hold of one. You can’t find original Nakamichi Calibration tapes.

No problem! I make the next best thing to the (expensive and unavailable) original Nakamichi test alignment tapes, using my set of originals and my Nakamichi T-100 Audio Analyzer, assorted bench gear, plus my long experience in thee world of Nakamichi Cassette Decks, and analog audio.

Beware of imitations and false claims! These tapes are the ones everybody is talking about, and I have been making them since 2005. Not one dissatisfied customer! Over 300 sets sold!

Require a custom calibration tape for your Deck Brand X? Please contact us, we can master almost any tape of any frequency, at any flux level from any reference level, Dolby 200nWb/m, VU 160nWb/m, or DIN 250nWb/m at very competitive prices! We master C-10 Type II tapes, but can provide almost any type in TDK / Maxell cassettes in C-60 or C-90 if required.

Can you do it? See the calibration Frequently Asked Questions

These are made to order on my CR7 or Dragon decks, making sure the decks are spot on before hand. Only then, I make a set of 2 EX cal. tapes, as follows:


  • Side A:5 min Level reference 400Hz 0dB, 200mW/m flux density
  • Side B: 5 min W&F 3KHz -5dB below 200nW/m flux density,


  • Side A:5 min Head Height Alignment 1KHz 0dB, 200mW/m flux density
  • Side B: 5 min Head Azimuth Alignment -20dB below 200nW/m flux density,
