Abstract:
A disk apparatus comprising:a disk rotating unit supporting and rotating a disk; a magnetic head reading data from and writing data to a surface of the disk; and a head carriage supporting the magnetic head and moving the magnetic head in a radial direction of the disk, the head carriage further comprising: a carriage body; a suspension having a base part fixed to the carriage body, the magnetic head being fixed to an end of the suspension so that the magnetic head is supported in a cantilever fashion, the suspension producing a head load pressure at which the magnetic head pushes the surface of the disk; and an adjustment member rotatably attached to the carriage body and arranged so that when the adjustment member makes contact with the suspension, a force is applied to the suspension based on the direction of rotation of the adjustment member to counteract or supplement the suspension force producing the head load pressure so that the head load pressure can be adjusted in collaboration with the suspension and the position of the adjustment member.
