Abstract

A control method for the angle servo of reference beam during reading recoded data images of a holographic data storage system is presented. The recording scheme with track offset is adopted in order to verify the proposed angle servo. Using only recorded data tracks the angle error signal of reference beam is generated and the angle servo is implemented. Experiments have been performed on recording and reading data images to compensate Bragg angle mismatch.
