Back in the day when duplicating tapes was a day job for me, they
said that side 2 of cassettes duped ay high speed both sides at once
would sound better than the side 1 would. Never made much difference
on cassettes, especially at 64 or 128IPS dupe speed, but some people
told me copying 2 tracks worked better in reverse too... They said
the electronics could respond to transients backwards better than
forwards. I have no empiric evidence of this though.
Just old tape tales by now, but this had me thinking back... or
I have transferred some quarter track tapes doing all four tracks at
once top a four channel A/D, and not noticed a significant
difference, but it is easier to do them one side at a time as then
they end up tails out, as long as it is an hourly job and not a mass
flat fee transfer project.
Hope this isn't irrelevant!
