Digital recording
A recording in which binary numbers are written to the tape (or disc) that represent quantized versions of the voltage signals from the recording microphone or the video camera.
On playback, the numbers are read and processed by a digital to analogue converter to produce an analogue output signal.
Multiple generations of digital recording do not suffer from degradation due to tape noise, moire, etc. However the tape is subject to wear and tear. The possibility of this producing errors and drop-outs necessitates error concealment circuitry. In extreme cases multiple passes can introduce cumulative texturing or other artifacts.
