  To the best of my knowledge, the fabrication of
1/2" tapes has seized.
 The last manufacturer was eMag, AFAIK. They are now even advertising
 a new service : recertification of old/used tapes. They are also largely
 out of stock now, with regard to new tapes.

We regularly purchase databases from outside sources. All but a few default
to sending these on 9-track 1/2" tape (the bigger reels too). The mail
houses still using the 1/2 tapes actually have a service charge of $75 to
$100 per ten-thousand names to put them on floppy, cd or email. Maybe
they're just trying to get rid of the thousands of junk tapes they have
around. Anyway, I end up with a closet full of tapes every year.
