A new scheme for generating a flat optical frequency comb using three Laser sources based on cascading of Dual Drive Mach Zehnder Modulator (DD-MZM) and Electro Absorption Modulator (EAM) through an ...

It is desirable for a dual-stage actuated (DSA) magnetic disk drive servo system to achieve fast and accurate read/write (R/W) head positioning. In the present study, we propose a DSA control scheme ...
