Was Beta as good as or better than reel to reel?

"VCR has width track but very slow speed"

That is misleading. The tape head in a SuperVHS HiFi deck is large, and spinning very fast, so even though the tape itself is not moving that quickly, the speed of the head relative to the tape is very fast. Also, it is writing the data semi-vertically to the tape, kind of like slash marks, in discrete stips. So they actually had better specs than anything else a normal human could afford. Very complicated mechanism, hard to keep them working, and not user-alignable, as far as I know.

vhs hi fi was better than consumer level reel to reel; beta had better video, but I can't recall if the sound specs were as good. The reason was, that head was spinning very fast, effectively yielding a very high tape speed. I used Canon. It was difficult to keep those machines working right, esp portable ones; very complex. wouldn't recommend them for that reason.
