Hi, The majority of the problems I have encountered with DAT tapes had to do with alignment of the heads on the DAT machine - the alignment is unforgiving. So...if the DAT was recorded with a machine that was misaligned (which commonly happened over time), it would only play back on the same machine _without_ it having been serviced or the heads re-aligned. If it turns out that your whole collection isn't playing back, I would suspect that the machine(s) your working with may have misaligned heads. Best to bring one of the machines to a repair person and see if that corrects the problem. The "physical" problems I have encountered with DAT tapes, have been digital dropouts - that, I'm afraid, I don't know what, if anything, can be done about; and they are, as many of you know, more significant than analogue dropouts. Yep, digital...
