Abstract: The present invention provides a novel apparatus for initializing phase-change optical disk, wherein the optical system has the capability of combining more than one high power laser diodes, which can focus the incident beam from high power laser diode in the radiated direction on a minute reflected multiple-face mirror, all reflected light will advance along the light path in the same direction and finally be focused on the phase-change optical recording material layer by the focusing lens of the automatic focusing system. Due to the special design of the optical system of the present invention, the initialization light source and some portions of optical devices are designed to be an initialization light source module. The initialization light source module and the automatic focusing system form two independent modules. In the optical system, the focusing depth of the focusing beam of the optical system increases more than about 9 times than that of the well-known method by using optical image transformation process twice, and the error tolerance for the system in the mechanical positioning of the automatic focusing system and the initialization light source module increases a lot. This characteristic not only can enhance the counter-interference capability of the initialization apparatus during initialization; but it can also make the initialization light source have the characteristic of easy-take-apart-for-fixing.

The whole magnetic conductor of internal stator tooth portion with the condition of connecting in a straight line is bended to form a ring-shaped integrated body of stator tooth portion and is embedded into the outer peripheral position slot of the stator core magnetic conductor. After that, the end plate is used to press and cover the outer peripheral edge and position slot of stator core magnetic conductor. Finally, screw bolt is used to lock and fix at the internal stator base so as to obtain the firmness of the whole structure for internal stator portion. Furthermore, the magnet excitation coil can also indirectly or directly wind in the densest way around the wire winding portion, which exhibits a mutually linked chain-type arrangement shape, of magnetic conductor for the tooth portion of internal stator so as to reach the maximum volume occupation rate of wire slot for the magnet excitation coil of internal stator. Therefore, the current flowing density of magnet excitation coil can be effectively raised to chase the maximum electromagnetic flux density. The final purpose is to complete the highest operation efficiency and operation torsion of the external rotator motor.
