The digital mode uses special cassettes (with sliding covers ala DAT)
that are one-sided *and* auto-reverse !. 
I.e. you get 45 + (clonk) + 45 minutes with DCC-90 tapes.

NICAM TV-stereo (currently in use in UK & Scandinavia) uses
10+4 bits, similar to the first 18 bits CD's (16+2).
(Floating bits)
