It isn't - there's something called 'Flux Transitions per Inch' (ftpi)
rating, which varies; I know of two levels in common use.  You have
probably been using 'DC600'-like tapes (or 'DC300'-like, if only 300ft
long); try 'DC6150'-like tapes, with the higher ftpi rating.  I am no
quarter-inch-tape expert, but believe DC6150's WILL be usable on any
drive, although DC600's will be cheaper on older or cheaper drives
that will only use their lower allowable ftpi-rating anyway.
