[ARSCLIST] Type II cassettes

["Casey, Michael T" <micasey@xxxxxxxxxxx>]

I'm trying to sort out the different types of Type II audio
cassettes--chromium dioxide and cobalt-doped ferric oxide--in hopes of
generating of list of brands in each category. It appears, for example,
that Maxell XLII are CrO2 while TDK SA are cobalt. Does anyone have
information on the formulation of other Type II brands?

Thanks,

Mike
