Quad era - Direct Cut Disc era (same time frame):
I was just thinking about this again (in view of the new QS encoded EP mentioned above), the same consumer electronics mags that covered Quad extensively also covered Direct Cut Discs extensively, but I don't recall a single instance where the Direct Cut Disc makers were asked about using a Quad matrix encoder in the production of Direct Cut Discs.
They could have used the original Scheiber matrix or EV Stereo-4, both of which just use phase reversals (simpler circuits), they would have decoded fairly well w/DynaQuad/Stereo-4/QS.
Anyone ever run across any info about using a matrix encoder in the production of Direct Cut Discs?
