    • In an optical recording medium drive apparatus, an optical recording medium is illuminated with a laser beam emitted from a head via an objected leans, and the head detects light reflected from the optical recording medium being illuminated with the laser beam. A signal generator generates a reflected light signal in accordance with the reflected light detected by the head. A controller drives the objective lens via a focusing unit, and detects peaks in the reflected light signal obtained when the objective lens is driven in a focusing direction. The controller determines whether the optical recording medium is of a single layer type or a multiple layer type by determining whether a pattern of the detected peaks is similar to one of patterns which can occur if the optical recording medium is of the single layer type.
    • 在光记录介质驱动装置中,通过经过反射的倾斜从头部发出的激光束照射光记录介质,并且头部检测由激光束照射的光记录介质反射的光。 信号发生器根据头部检测到的反射光产生反射光信号。 控制器通过聚焦单元驱动物镜,并且检测当在聚焦方向上驱动物镜时获得的反射光信号中的峰值。 控制器通过确定检测到的峰值的图案是否类似于如果光学记录介质是单层类型可能发生的图案之一,则确定光学记录介质是单层还是多层型。

    • A diaphragm actuator having a diaphragm therein which is installed inside a cup so as to form a pressure chamber and a pressure is supplied to the pressure chamber so as to actuate the diaphragm and a rod connected to the diaphragm. The rod is supported by a bearing disposed inside the cup so that the diaphragm actuator is excellent in thermal insulation against the surrounding atmospheric temperature, thus preventing the diaphragm from being thermally deteriorated. To achieve this end, the bearing is extended to an inner peripheral surface of the cup until it touches the inner peripheral surface, and a contact surface of the bearing with the rod is formed in an arc-shaped section having the least inner diameter at its axial center.
