- Au contraire, VCR technology is expensive. Cheap, nasty cassette
- players cost ten pounds. DCC's only expense over a grungy cassette
- mechanism is the head, which isn't a moving part but is more complex
- than a standard analogue head. But in the digital domain problems like
- wow and flutter can be addressed by buffering, and high mechanical
- accuracy is what costs money.

- On the other hand, a VCR costs at least 15 times that. The mechanism is
- far more complex and the mechanical accuracy required to track the heads
- is not trivial. DAT machines have the same strictures on smaller tapes
- and far smaller track widths. I looked inside my DAT machine recently.
- There's a hell of a lot of ironmongery and a few small PCBs.
