When stepping into the D and MP3 areas, the precision required by the DVD and MP3 is relatively high. Therefore, it is necessary to adjust the angle between the laser in the read head and the disk by the fine adjustment mechanism after the device is assembled. The data on the disc can be read. However, the known disk drive requires fine adjustment by a fine operation of an expert in order to make the reading of the read head more accurate after the parts are assembled and combined, and this adjustment process is time-consuming. Not only wasted, but also labor costs were added, the production volume was reduced, and the product price was increased.

すかった。Further, in the well-known disk transmission mechanism, a plurality of driven gear sets are combined with a drive motor, one screw rod is penetrated by the side of the read head sheet, and the drive of the motor and the gear set is transmitted. By rotating the screw rod, the read head is driven and operated. In such a structure in which the reading head is driven and moved by the screw rod, the screw thread that combines both the screw rod and the reading head sheet needs to be relatively precise, which results in relatively high processing cost. In addition, the well-known method of driving and moving the reading head by rotating the screw rod requires a relatively smooth transmission effect between the thread of the screw rod and the reading head sheet, so that an appropriate gap is provided between the two. However, due to this gap, the accuracy of the laser reading angle of the reading head was rather insufficient, and the reading effect failure was likely to occur, and the phenomenon of skipping was likely to occur due to slight vibration.
