Thinking about how narrow those tracks would have to be on a quad cassette, Philips's way, it would be very tricky to keep those heads properly aligned. I realize Philips wanted to make all cassettes playable on all cassette players, but this would have been the one exception to the rule.https://worldradiohistory.com/Archive-All-Audio/Archive-HiFI-Stereo/SPECIALS/Stereo-Review-Tape-Recording-Guide-1974.pdf#page=64^^^
Philips has repeatedly suggested that the way to four-channel cassettes must involve a further reduction of track width. Specifically, this is eight very narrow tracks all within the width of a little more than 1/8inch...
So...it was a Philips idea, I suppose that the Astrocom 307 could have allowed Dolby B for Stereo cassette recording, but not for Quad cassette recording (possibly pacifying Dolby Labs).
(My interest in Audio began with receiving a compact cassette recorder for Christmas 1969 [a Craig 2610], so I followed developments in the compact cassette format closely)
