Sounds suspiciously like an RK05.  We used a lot of those on DEC PDP-8e's.  I can remember how startled I was when I first saw a DEC engineer pull the top off one and then, with it open, spin it up.  The platter inside was warped (a ceiling light reflected off the platter wiggled and then blurred) but the head mechanism actually just followed it up and down!!!
