When the speed of rotation of the head is such that
the lever 37 cannot be conveniently operated by hand,
a suitable mechanical coupling can be provided. Al
though it is preferable that, as in the embodiment de
scribed, the movement of the track should have acorn
ponent which is simple rotation about its axis and that
this movement should be complex, in that the axis of
the track itself also moves around a_ parallel axis, the
track may move around an axis parallel to its own axis
without rotating about its own axis.
