Here is some information off the little hoard of tapes I have.

Six tapes in the fitted plastic box.
Philips brand, Certified Digital mini-cassette LDB 4401, made in Austria,
8920 440 10101. One has a tape label with hand printed Transport 1.1 and
1.2. None are sealed, but none but the label unit look particularly used.

Rewinding one with a pencil revealed nothing special, ie no mirror.

The drive has a HP brand tape in it, but that goes with the drive to Stan.

If you want a tape, email me and I will work out some nominal fee, most
likely by listing one on eBay to see if I am insane for parting with them
first, but keeping it nominal for people on the list.
