| Abstract: | The multi beam holographic optical head which combines the multi beam optical head with holographic optical head is proposed. This optical head has a light and compact structure, and works with parallel mode. Consequently, it not only can improve data transfer rate of driver but also shorten the random access time. In this paper, the multi beam holographic optical head is investigated theoretically and experimentally. |
