Head assembly including a variable device for adjusting an inclination of a slider

Abstract

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.
