GennLab Standard Alignment Tapes
1/4" Reel-to-Reel Speed adjustment
Speed from 1-7/8 to 30 in/sec (4.7625 to 76.2 cm/sec)
Each Calibration Tape is a Single-tone Full-track Master tape (not a copy).
Tapes are recorded using an OTARI MTR-12 or STUDER A810 Reel-to-Reel production full-track tape recorders and professional test equipment from NTI (NEUTRIK). The Capstan motor of the tape recorder is controlled by digital Quartz- Locked PLL. This can work at standard speeds with 0.01% (typical) accuracy, and at any speed from 1-7/8 to 30 in/s using an external digital clock generator.
If required a tape can be recorded at any speed from 1-7/8 in/s to 30 in/s.

RtR Tape Deck speed alignment
Attach the 3000 Hz or 3150 Speed test tape to a 10-1/2" NAB reel for high speed or to a 7" EIA reel for low speed.
The tape frequency reading gradually drops slowly towards the end of 4 min. portion of the tape.
This is normal, and it depends on the deck mechanism condition.
To check your deck mechanism condition do following:
1. Read the deck Speed specifications (15" or 7.5" +/- .%).
2. Calculate +/- .Hz tolerance from 3000 or 3150 Hz.
3. Playback ANY tape for 2 minutes to warm up motors and mechanism.
4. Put the Speed tape on the Supply Reel table. Playback the Speed tape from the beginning of the tape for 1 min. Note the frequency in Hz at the end of the 1 min. portion of the tape.
Say this is the Frequency at the Beginning of the Speed tape.
5. Stop the deck. Flip over the reels. The 1 min. portion becomes the last minute of the tape.
6. Playback the tape from that 1 min. position and note the frequency in Hz at the beginning of that 1 min. portion of the tape.
Say this is the Frequency at the End of the Speed tape.
7. Check if the frequency difference in Hz is within the deck's Speed specifications tolerance.
If not, several things could be the reason: too high back tension of the supply reel (dirty friction felt or misalignment), not enough friction in the capstan-pinch roller pair (dirty or dried out pinch roller), dried out capstan bearings lubrication, dried out and loose capstan belt, dried out motor bearings lubrication etc.
8. Finally, calculate the Average Frequency.
F average = (F beginning + F end)/2. Calculate the Average Frequency Deviation from the Tape Nominal Frequency. Deviation = F average - F nominal. Adjust speed of the deck to obtain minimum possible Deviation.
