Light Delivery

The light delivery system is an important component in heat-assisted magnetic recording technology. It needs a light source and delivery the laser beam to the slider for writing process. However, the different designs lead to the different manufacturing processes, number of process steps and technologies consequently affect to the fabrication cost. This paper aims to propose an alternative design for a light delivery system. The complicated processes to manage a heat in a manufacturing are also take into account to have the final product meets the requirement for HAMR technology. The components are also fabricated which is made for a design and also presented.
