Description
Summary:One of the trends on information storage device is focused on the development of small form factor optical disk drives with Optical Flying Head (OFH). Many different types of sliders for OFH and optical component systems have been introduced in the literature. However, the research about the actuating system is not much in the literature. In order for a slider with OFH to be successfully implemented in the system, a suspension is needed to be properly designed. Generally, a suspension supports slider performance, and tracking servo capacity in HDD. As the suspension supported the OFH slider which has larger mass and objective lens, it is required to satisfy shock performances for the mobility, and it also should meet the optical characteristics. In this study, the suspension for small form factor ODD is designed with sensitivity analysis. The dynamic characteristics of the suspension with OFH are analyzed finite element method and experiment, and the flying height and its variation of the OFH slider is measured by laser doppler vibrometer.
