A head assembly includes a suspension coupled to an end portion of an
actuator arm located on a base to rotate around a pivot shaft, a head
slider installed at the suspension and having a head to record and/or
read information on and/or from a recording medium, and a variable device
located between the suspension and the head slider, wherein one side of
the variable device is coupled to the suspension to adjust a flying
height of the head slider by adjusting inclination of the head slider
with respect to the suspension. The head assembly can be applied to a
magnetic head assembly by using a magnetic head and a magnetic disk as
the head and the recording medium, respectively. Thus, since the variable
device can be fixedly coupled to the suspension during the assembly
process of the head assembly or the manufacture of the suspension, the
process of manufacture is considerably simplified compared to the
conventional magnetic head assembly. Also, since the head assembly
according to the present invention adopts a manner of directly
controlling the flying height by adjusting the thickness of the variable
device to adjust the pitch angle of the magnetic head slider, the flying
height can be accurately and actively controlled so that a fast switch of
the flying height is possible.
