ABSTRACT:
A fulcrum for the swing of an arm 5 holding a first magnetic head 2 is provided by a rotation fulcrum pin 21 which is supported on sloped sidewalls of V-shaped grooves 23. A leaf spring 24 pushes the rotation fulcrum pin 21 against the sloped sidewalls grooves 23 at all times. The opening stroke of the arm 5 is not limited by the fulcrum and the rigidity of the arm 5 at the fulcrum is increased.
