Abstract

PURPOSE:To increase the write-in aligning accuracy, by controlling the movement of a rotable member provided with the servo information write-in head via the actuator which is in straight line movement through the provision of position measuring mirror. CONSTITUTION:The head bar 120 provided with the servo information write-in head 119 at the tip rotable around the shaft 121 as the center, and the linear carriage 105 forming the actuator and in straight line movement via the voice coil motor bobbin 106, are coupled with the link mechanism 123 consisting of the pin 127 and the tension spring 126. Further, the mirror device for position measuring which reflects the laser light is provided at the carriage 105 in straight line movement. Thus, the position measurement can be made in high accuracy and the rigidity of the bar 120 unnecessary for the mirror can be increased, allowing to prevent the production of resonance with high resonance point. As a result, the write-in alignment of the servo track is increased with accuracy.
