Paper Abstract

The multi-beam holographic optical head that combines multi- beam with holographic is proposed. This optical head has a light and compact structure, and work with parallel mode. As a result, the data transfer rate of optical disc drive can increase by several or tens times. The designing and fabricating of the key component of the multi-beam holographic optical head based on above designing are discussed also. The mathematical model of this optical head's diffraction is obtained by theory, the simulating of the multi-beam holographic optical head is carried out by computer. As a result, all kinds of signal waveform of each channel are obtained, including data signa, focus error signa, and tracking error signal. It is proved by the result that the multi-beam holographic optical head is a practicable method to realize the parallel reading/writing of optical disc drive.
