For those interested in a first-hand account of Cinerama, Hazard "Buzz" Reeves wrote a two-part 
history for the SMPTE Journal, October and November 1982 issues. Reeves's magnetic media division, 
in Danbury CT, was also an early producer of mag-stripe stock for the many-channel release formats 
of the early 50's. Regarding the early mag-film formats, SMPTE produced a special publication on 
magnetic film recording/playback and stereophony in 1952.

Add one- Hazard Reeves' Cinerama used 35 mm fullcoat and had 7 active audio channels. I have the 
remains of one of the playback heads.

35mm actually allows up to 6 tracks on full-coat, with many other varients:

I've seen one-track, 3-track, 4-track and 6-track 35mm mag-film recorders and dubbers.

I've never seen a 16mm full-coat mag-film, just 17.5mm. I'm sure 16mm exists, I'm just not sure of
any standard formats as far as tracks. I assume single-track was definitely an option.

Hi Shai,
In my experience, there is usually just one track on 16mm fullcoat. 35mm fullcoat allows room and
width for three tracks or stripes if it's been coated that way.

 Does anyone have information about the standard used to record audio on 16mm full coat film. A
project came in where the audio for the film is on full coat 16mm and I wonder how many tracks could
there be or how many formats. Any info or links will be appreciated.
