An experimental holographic media storage system uses a flexible photopolymer disk. During rotation, the disk tilts, making information retrieval difficult. A system that compensates for the tilt has been developed. For this, a laser beam is focused on the disk surface and disk variations are measured through reflection. A mirror is in turn adjusted to align with the disk and makes information retrieval possible. A video camera provides the sight for the robot and the tracking loop. Assuming the system transfer function is given by G(s)=- use frequency response techniques to determine the following i) ii) 25(s+1) s(s+2)(s² +2s+16) Gain margin, phase margin, zero dB frequency, and 180° frequency Is the system stable? Why? ( ļ
