distortionless
a. Lacking distortion
Usage examples of "distortionless".
The geometry is entirely radial, so there are no edge-bleeding effects, and, as far as I can tell, the thing is distortionless, intertialess, and self-interference-free, so that anything stored on it will last until the end of time, or until quanta-level decay erodes the fundamental substructure of the behavior of basic particles, whichever comes first.
