The present invention provides a head support mechanism wherein the
position can be accurately corrected at a high speed when the mode is
shifted from reproducing to recording, and also, the deflection of
recording magnetic field from the direction of initialized magnetic
orientation is little and it is possible to suppress the deterioration of
the recording characteristics and to make the skew very small. The first
link 3 and the second link 4 respectively rotate about the first
rotational center 5a and the second rotational center 5b, to which the
third link 7 and the fourth link 8 are rotatably connected. The lengths
of the first link 3 and the second link 4 are nearly equal to each other,
and the lengths of the third link 7 and the fourth link 8 are set to a
length nearly equal to the distance between the first rotational center
5a and the second rotational center 5b. As the first link 3 rotates, the
third link 7 and the fourth link 8 reciprocate while keeping a state of
being parallel to the diametric line 9 of the recording medium that
connects the first rotational center 5a to the second rotational center
5b, and then the sliders 10 mounted with magnetic heads of the suspension
11a and 11b fixed thereon reciprocate.
