Abstract
First and second magnetic heads, or magnetic head sliders containing these heads, which are brought into contact with a magnetic disc on its both sides so as to record and reproduce information signals, are respectively supported by first and second swing arms. The first and second swing arms are respectively supported by first and second elastic bodies. The swing arms are respectively provided with first and second adjusting screws for adjusting the movable range of the swing arms. The first adjusting screw operates to adjust the pressure of a first spring supported by the first arm and the position of the first magnetic head. The second adjusting screw operates to locate the associated second magnetic head to a position which is adjusted to the thus-adjusted position of the first magnetic head.
