I think it goes back a lot farther than that.  This baby certainly had 
flex cables on the heads.  With the right access pattern the heavy, 
hydraulically actuated read/write heads were prone to setting up a 
sympathetic side-to-side vibration that could cause the machine to try 
to walk across the floor.  I've seen one break its 400 volt power cable 
when it started to walk before I could stop it.  But I don't think it 
broke flex cables on the heads.  I operated one for a year in 1965/66. 
It was part of a manufacturing control system which operated pretty much 
24/7.  I don't recall any other failures beyond the stretched power 
cable and a burned circuit board caused by contaminated water from the 
A/C system on the floor above dripping through a crack in the floor and 
into the machine.  The cat's meow.  25-28 million characters (not bytes) 
storage capacity and it only cost $2,100/month on lease.  Woo hoo!
