T120 vs E180

[Kevin Charles Rubio]

I'd like someone to verify my calculations about VHS tapes ...

If a PAL VCR was using an American T120 tape on PAL LP speed, would the
playing time be 342 minutes -- 18 minutes shorter than PAL LP on a British
E180 tape?

This would mean that PAL LP runs just slightly faster than NTSC EP...?

T120 tapes are 246 metres. How long are E180 tapes? They're only slightly
longer, right? I heard that an E180 is equivalent to T126, and that T120
is equivalent to E171.

This post reminded me. All Beta tapes that I purchase give the recording
time for B1, 2, and 3 recording modes in NTSC, but list only one recording
time for PAL. Do PAL Betamaxes record in only one mode? Hard to believe!

As a Beta user in a PAL country (not many of us left in Australia) I can
tell you that I have never seen a PAL VCR that supported any form of
multi-speed recording/playback.

Nor am I aware of there ever having been an ED-beta Pal unit, although
they may have been released in the European and/or Middle Eastern markets.
Super-Beta is as far as we got.

And just as a side issue, I understand that Beta-Hifi on PAL units uses
depth multiplexing (per VHS-HIFI) which is quite different to the technique
used for NTSC - or have I got that wrong?
