1/4" 3M 968 equivalent (for Nagra)?

Recommended Posts

Help me, fellow oldsters!  I have a gig for which I need to use my venerable but neglected Nagra IV-S.  The machine is still set up for 3M 968.  Is there a 1/4" tape currently being made that uses close to the same setup+bias etc?  ATR?  7" reels needed, plan to use Nagramaster.....

Hi Philip,


In the lack of any information I would simply do a test at -20dB of tone fro 1K to 15K

in order to see if the tape you have gives a realistically flat response.


If you get into re-biasing you would also need to adjust record amp for H2 and H3 distortion


I used to align my two 4.2 recorders and got it down to a fine and satisfying art


Good luck
