Level variation
This new head has a hyperbolic shape so that the pressure of the tape against the
head is concentrated between the recording and playback gaps;
level variation is
further improved by the DD dual capstan mechanism.
e Wow and Flutter
With the new uni-torque direct drive motor employed in the D-3300M, a low wow
and flutter of 0.023% is achieved.
