I corrected myself, it's just because you're looking younger on your
photos ;). Of cause, I guess the Telefunk - or was it AEG? - machines
were without tubes. The magnetic tape head had visible slots. On Fri, 2010-12-17 at 05:30 -0500, gene heskett

Some maybe. I have a 1Gb seacrate hawk I use on a TRS-80 Color
Computer that is a good 15 years old, and I hooked up an old Quantum
P40S beside it the other day that must be close to 18 years old. No
bad sectors were found when I did a logical verify of the surface.
Ok, my 40MB SCSI Seagate for the Atari is ok for more than 20 years,
heavy usage, several startups a day. Sometimes I need to start it 2 or 3
times, but than it's ok.

That seems to be a recipe for disaster. Will there be a working tape
drive to read those old tapes in even 40 years?
For analog tapes Dirk Brauner had Telefunken machines that are as old as
you are and they were better than a lot of modern machines ;).
Because the tapes were stored spooled to the end, there even was no
audible crosstalk at the beginning of the recordings.
