abstract

The aim of this paper is to investigate the effect of roller leveling process on the behavior of microstructure in flexible magnetic medium. Linear magnetic encoder is a highly precise measuring device that required accurate quality control during manufacturing. Previous studies have demonstrated the feasibility of roller leveling application to enhance the manufacturing of flexible magnetic medium. Mechanical shape defects in magnetic medium occurred during manufacturing due to environmental conditions can be eliminated through roller leveling process. In this paper, further steps were taken to understand the effect of roller leveling process in the microstructural level. From experimental results, it demonstrates that roller leveling process, a type of cyclic loading process, would not encourage crack growth if cracks were not initiated prior to leveling process. In addition to removing mechanical shape defects, understanding roller leveling process in magnetic medium application through investigating microstructure behavior has implications toward the fabrication quality of flexible magnetic medium.
