Abstract
'Coil' occupies very much important position in delivering driving force of optical pick-up actuators. Up to now the main stream has been a winding coil type actuator, but actuators using FP-Coil(fine pattern coil) have been considered for the more compacted and simple manufacturing process and have variously spreaded the application fields by product. We have tried to design actuators using PCB-Coil(printed circuit board coil) which has benefits in terms of price and manufacturing process. Especially this research has two main things to reduce the vibration of sub-resonance and to assure the DC sensitivity among the performances of asymmetric optical pick-up actuator with PCB-Coil.
