We have investigated a clock generated from a wobbled groove for higher density magneto-optical disk. Neither the readout signal nor the recording signal needs to include a clock element, because a clock derived from the wobbled groove is used for recording and readout. Therefore this clock does not depend on the quality of the readout signal. For this reason, a clock generated from the wobbled groove is effective for higher density recording.

Laser beam scanning technology has been used in various machinery such as laser beam printers, laser processing machines. Recently, the usage such as distance sensors for automobiles, area sensors for robots has expanded further. According to it, the miniaturization of beam scanning equipment, advanced features, and low-pricing have also come to be called for strongly. We suggest a method of two-dimensional beam scanning by driving a lens with an electromagnetic actuator. We use suspension wires to hold the scan lens. As a result, two-dimensional beam scanning is possible by simple structure. This paper describes the structure of the scanner module system and characteristics of the prototype model.
