- Having been an Audio DAT user for over 5 years and an Indigo user
- for about 3 months, I haven't encountered an audible nor any other
- critical error with DAT tape. I use various length of tape (60, 90,
- 120 min.) manufactured by Sony, Panasonic, etc. but they all seems
- to be working fine also on Indigo.
-
- I don't know the difference between DAT tapes for audio and for data
- except there are special tape length for data storage (i.e. 90 meter).
- It is indeed confusing that there are DAT tapes for general use,
- data storage use and for professional recording! ( What about
- "professional" data storage? :-p)
-
- I >>personally<< think you can share DAT audio tape for data storage
- with Indigo considering that SGI's DAT drive switches it's mode
- between audio player/recorder and data streamer in error correction
- coding strategies and other stuffs. In other words, you can get the
- higher data reliability in data storage mode even if you use a tape
- for audio use as well. Maybe the situation might change when SGI's
- DAT implements data compression.
-
- I am not sure about the life expectancy of DAT tape, but they are
- designed to endure hundreds of scanning pass by the rotary heads
- and the recorded data are supposed to remain readable for almost
- hundred of years without overwriting.
-
- Sorry I don't have any information about mail-ordering.
