i live close to the water and humidity is a real killer .. the tdc-3820 &
tdc3660 have been completely reliable. others with dat and 4 mm stuff suffer
badly with humidity and corrupted tape fs's.

a friend of mine once said that the day the dat manufactures take the rest of
the vcr technology and impliment it then dats will be as reliable as home vcrs.
but they will always have the problems inherant with the narrow media and the
stresses associated with the high (relataive to tape movement and head
acceleration) speed of the transportation mechanism.

did, jeorg. thanks, it made my day
