Yes, the stereo audio tracks on VHS are linear tracks, i.e. they are recorded
by the same method used to record audio tape.  The HiFi audio tracks (also
stereo) are recorded under (or deeper) than the video signal by 2 or more
additional audio heads on the rotating (video) head drum.  The HiFi tracks
are frequency multiplexed and recorded as one signal.  Two (or more) HiFi
audio heads are used since the tape doesn't wrap completely around the head
drum.
