- Let's be clear here. If you make a DIGITAL to DIGITAL copy from
- one DCC (or MD) to another, you don't get a perfect copy of the
- tape either. This is because the data on the tape has to be
- converted to the format of the interface (i.e. uncompressed) and
- then converted back again. And we are being told that these
- compression algorithms add more noise to the signal every time you
- do this.
