I have had problems with new DATs. The slightest alignment problem seems
to cause significant problems.

My main concern has to do with the density of the oxide and the nature of
the scan. Since the recording process is similar to the VHS, are DATs not
just as likely to suffer the same fate as VHS and have a similar life
