[QUOTE="jeallen01, post: 1012899, member: 176704"] This thread jogs a very old memory of when (late 1980s) I was working for HP at Bristol, and one of the last projects in which I was peripherally involved was the development of the very first DAT drive, using a Sony mechanism. My role was to try to work out the environmental test spec for these drives - the "shake & bake" stuff was relatively straightforward, but the EMC spec was a real challenge because all the tests in the standards were for complete, ready for use kit but there was nothing I could find about the very near field EM environment that units inside the complete enclosures would encounter. Short story: lots of experimental conducted and radiated testing, and several "nearly" blown up bits of kit borrowed from other departments - and some not entirely conclusive test results, but hopefully those helped in the long run. Also, much, much later, got my hands on one of the original drives and some tapes (out of nostalgia as much as anything), but never made any use of them because, as has been mentioned before, by that time the tapes could not hold anywhere near enough data to be of any real help - so binned the whole lot a few years ago:rolleyes: [/QUOTE]
