Personally I would never have declared it as an alternative to CD, but it was a convenient alternative to compact cassette if you needed long running times. The "hifi" track was placed alongside the video with an extra set of heads, and obviously the non-hifi linear track had to remain where it always was and contain a replica of the audio for compatibility with other decks. There were i think a few decks that offered linear stereo audio too, but not many and I don't think it was very good (particularly when long play came along)..
