This ratio of 60 to 71 gave a reduced variable density track having a width of inch instead of the -inch width called for by the 1934 standard. Eventually the 35-mm. Standard was changed to specify a track space inch wide in v.ariable-width recording. This track, on the optical reduction printer, gave a 16-mm. Print having a track width of inch.
