From Steven C. Barr: "...The apparent assumption was that, since
tracked at a gram or less...therefore, the LP's could be MUCH
thinner and still survive regular use...?..."
The purer vinyl could survive regular use better no matter what the tracking
force and it was lots quieter. Making it thinner saved a bundle on shipping
costs which more than made up for using more expensive vinyl. What they
didn't figure on was the increase in the amount of warping in transit.
