Abstract :
This paper presents thermal analysis of spindle disk assembly used in computer hard disk with new design approach of spindle to minimize the repeatable run-out (RRO) of track following position error signal (PES) in high track per inch (TPI) disk drives. Analysis has been taken on different operational temperatures (25°C - 80°C). By varying the notch angle (0° - 45°) in spindle, it has been found that RRO can be minimized significantly. FEA simulation results have been presented to verify the findings.
