Abstract

A moving-magnet type pickup actuator has an assembly error. That is, the actuating Part of an actuator is shifted from initial position after we assemble it into yoke. This Is the result of an effect of magnetic force between magnet and yoke. We performed magnetic-analysis using FEA. As a result of simulation, we improved the assembling efficiency for moving-magnet type actuator.
