초록정보

The current trends in the computer and communication industries are towards increasingly high resolution images and video processing tasks require massive storage systems and video processing. However such sophisticated processing tasks require massive storage systems such as CD-ROM, digital video disk, etc. Current demands in the development of such systems are greater storage densities and higher data transfer rates. The critical issues in this area are originally shortening the laser wavelength and improving head positioning precision. The latter is concentrated on in the paper. There are several methods for increasing data transfer rate. One method is to rotate an optical disk at higher speed. However, it is difficult to realize a higher rotation speed than an applied speed commercially, because frequency response characteristics of an objective lens actuator are insufficient to follow the axial and radial movement of the disk precisely and the mechanical speed limits of spindle motor. On the other hand, a multi-beam optical disk drive is presented as a method for improving the effective data transfer rate by increasing the spot number formed on an optical disk. The purpose of this study is to design the pick-up part of multi-beam optical disk system and to verify the system efficiency. To rotate the multi-beam, image rotator was designed. Image rotator consists of dove prism and piezo material and has a good frequency response. So it can be used in multi-beam disk drives.
