OT:bias frequency

["Pete Mundt" <manx72@voyager.net>]

O.K. Maybe a very stupid question, possibly a very stupid question

anyway,    anybody know the approximate frequency at which tape bias
occurs???

I'm trying to master stereo mixes (which were recorded on 8-track cassette)
on my computer, and would love to be able to take out some bias.

I have cakewalk 8 @ my disposal. Any suggestions are very much appreciated.
