This paper presents a measurement method for plate convex contour measurement by contact force. During the measured mechanical part rotation, the stylus slides forward or backward by servo motor and ball screw movement. The contact force is detected by sensors according to distance between the measured part and the stylus. The servo motor displacement has been used to calculate the radial value from the center of rotation to the tip of the stylus, and the contour points coordinates can be measured in sequence continuous measurement. By mechanical transmission gap compensation and force compensation, the better profile accuracy and effectiveness can be gotten.

A non-contact angular measurement system for Pitch Static Attitude (PSA) and Roll Static Attitude (RSA) of hard disk drive sliders is designed and built. Real-time sampling at over 15 KHz is achieved with accuracy of +/−0.05 degrees over a range of approximately 2–3 degrees. Measuring the PSA and RSA is critical for hard drive manufacturers to control and improve the quality and reliability of hard drives. Although the hard drive industry is able to measure the PSA and RSA at the subassembly level at this time, there is no system available that is able to measure PSA/RSA at the final assembly level. This project has successfully demonstrated a methodology that the PSA/RSA can be reliably measured in-situ using a laser and position sensitive detector (PSD) technology. A prototype of the measurement system has been built. This device will allow a continuous measurement between the parked position on the ramp and the loading position just off of the disk surface. This measured data can be used to verify manufacturing processes and reliability data.
