[78-L] Extra long Lps, was Re: 10" vs. 12" LPs

[Bertrand CHAUMELLE]

What about the Trimicron MDR LPs ? Up to 60 minutes of music in stereo 
per side.
MDR was E. Rabe's process (Magnetic Disc Recording).

MDR also invented a videodisc system (12", 20 minutes per side, 
120rpm). It was demonstrated in Paris in 1974; the same machine could 
be used to play LPs, too.

I've never seen an evaluation of the system in print, but I own several 
of their 12" and 7" records.
