Abstract:
A method of making a head disk assembly using a servo track writer, the head disk assembly including an enclosure having an opening and a base, an actuator arm coupled to the base and having a servo writer positioning arm facing surface, a disk coupled to the base and having a recording surface, the servo track writer including a platform for coupling to the head disk assembly, a servo writer positioning arm coupled to the platform, the positioning arm including a main body, a tip having an actuator arm facing surface, and a vibration damper positioned between the main body and the tip, the method comprising the steps of:providing the positioning arm through the opening;rotating the disk; andwhile the disk is rotating:positioning the actuator arm over the recording surface;biasing the actuator arm against the tip such that the positioning arm facing surface abuts the arm facing surface; andwhile the actuator arm is biased against the tip:damping vibrations induced in the actuator arm by way of the vibration damper dissipating energy transferred between the platform and the actuator arm.
