47,488 -21- ABSTRACT OF THE DISCLOSURE A load survey tape recorder has a tape transport assembly including a supply spindle assembly having a magnetic brake and a take-up spindle assembly having a magnetic clutch. Substantially constant tensions are main- tained in a recording tape as it is driven between supply and take-up reels by the magnetic retarding forces Or the magnetic brake and by a variable magnetic drive coupling of the magnetic clutch. A non-magnetic spacer is placed in one or both of the magnetic coupling gaps of the brake and clutch for improved operation.
