pwhodges:
"Mono-compatible" on a stereo LP simply meant that the LF components of the difference signal were attenuated so that a pickup not designed to track the vertical movement wouldn't get thrown out of the groove.

Although there have been pickups that sensed the horizontal and vertical movements and matrixed them (in the sensor coils, or a separate transformer) to generate left and right outputs, most pickups are actually mechanically arranged so that the two 45° movements actuate separate sensors so that no matrixing is necessary.

Tova:
I see! Thanks for that bit of info.
