Like bruce said.... it requires medical attention!
And while this may be what it really needs, it still doesn't hurt to try a different brand of tape first!
One of my old Blackface units didn't like Ampex tape at all!!! Ate like 3 or 4 of them. Switched over to Maxells and never had a problem again!!!
Sometimes the tape manufactures screw up a batch, and they don't align correctly in the deck, and the tape get's eaten. Of course, recall's on SVHS tapes doesn't really happen much, and finding out that a batch might have a problem is an iffy proposition. Also, it just could be that the loading mechanism doesn't like how HHB's load in. Even a of millimeter of difference in a certain dimension on the cassette itself could make it load wrong.
A repair shop bill will be AT LEAST $45-$60 (one hour minimum shop rate usually applies, whether they work on your unit an hour or not! But those creeps ALWAYS find a way to charge you for yet even MORE labor....

) and a new Maxell Professional tape only costs no more than $15. If the tape is the culprit, you saved a bundle. If the unit is screwed up, well, you are possibly out a few more bucks, but, seldomly do the tapes get eaten to the point that they are totally unusable. Fast Forward to almost the end of the tape before playing or recording on it for this test, and that way, as long as the tape didn't actually break, the first 35 minutes or so is still very usable. Just the last 5-7 minutes won't be. That way you can still use the tape after you get the unit fixed (if the different BRAND of tape thing doesn't work).
I have seen HHB's, Apogee's, Ampex, and BASF (I can't think of the other brand I have seen problems with too) ALL have problems with ADAT's!!! Maxell is the only brand I have never had a problem with. Try a new brand of tape first. Then take to repair shop if that doesn't work.
