Looking for some further insight into 'Error 03' messages

I have a question regarding ‘Error 03’ messages, which I’ve been seeing occasionally on my Tascam DA-30mkII DAT machine. I believe it happens with certain tapes rather than random tapes. I am aware that this code means ‘broken tape’ or something to that effect (even though I know the tapes are not 'broken'). Usually when the drawer closes after loading a tape, I hear the normal ‘mechanical sounds’ that I normally associate with the tape being engaged to the heads etc.. However, when I happen to load a tape with an ‘Error 03’, I do not hear any of these sounds – the drawer closes and then…nothing (just ‘Error 03’ appears). I often find that after opening and then closing the drawer, the tape loads normally with the familiar sounds and plays perfectly. I have never yet seen any ‘Error 01’ messages or other stuff that I see other people have had problems with. Basically I was just wondering whether this is anything I should be worrying about with regard to my machine, or this is really more of a tape issue rather than a machine issue? Just looking for some peace of mind regarding my DAT deck which has otherwise performed very well in every other respect.
