A helical scan tape drive (30) which transduces information relative to magnetic tape (31) using an active head set mounted on a rotating scanner (84). A non-transducing body, comparably configured to a transducing head, is mounted upstream from the active head set (82) in a direction of scanner rotation. The mounting of the non-transducing body serves to stabilize a head-to-tape interface at the active head set, resulting in an essentially uniform signal amplitude from a head in the active head set, including a leading or trailing head in the active head set. Even over wide ranges of tape tension, scanner speeds, and tape thickness, the amplitude of the read/write signal for both the leading and trailing heads are "flat" and steady. In one embodiment, the non-transducing body is a dummy head (80).
