    摘要： For recording or reproduction of information, the optical beam is moved relative to the recording medium along the longitudinal direction of a certain track. When accessing another track, the relative movement of the light beam along the longitudinal direction of the track is decelerated, and during this deceleration, the light beam is started to move in the direction transverse to the tracks toward the desired track. Thus, it is not necessary to wait for such time when the relative movement of the light beam along the longitudinal direction of the track has been completely stopped, and hence the necessary accessing time can substantially be reduced. If control is made to cause a decelerating rate of the relative movement to decrease continuously gradually or stepwise from a relatively high decelerating rate to a relatively low rate and the light beam is caused to start relatively moving toward the desired track while the relative movement is at the relatively low decelerating rate, it is allowed to effectively suppress occurrence of unwanted mechanical vibration due to abrupt deceleration of the relative movement.

    摘要翻译： 为了记录或再现信息，光束相对于记录介质沿着某个轨道的纵向方向移动。 当进入另一个轨道时，沿着轨道的纵向方向的光束的相对移动减速，并且在该减速期间，光束开始沿着横向于轨道的方向朝期望的轨道移动。 因此，当光束沿着轨道的纵向的相对移动已经完全停止时，不需要等待这样的时间，因此可以显着地减少必要的访问时间。 如果进行控制使得相对运动的减速率从相对较高的减速速率逐渐或逐步地减小到相对较低的速率，并且使光束在相对运动处于 相对较低的减速率，能够有效地抑制由于相对运动的急剧减速引起的不希望的机械振动的发生。

    摘要： In a tracking or focusing servo control loop, there are provided a switch element for switch-controlling a tracking or focusing error signal, and a smoothing circuit for switching passage the error signal. An amount of detected reflection from an optical recording medium is monitored by a controller section, and the switching action of the switch element is ON/OFF-controlled by the controller section so as to maintain a servo loop gain at a predetermined standard. Thus, it is possible to maintain a constant servo loop gain without being influenced by variation in the laser light amount or difference in reflectivity characteristics of the recording layers of individual optical recording media, and constantly stable tracking servo control and/or focusing servo control can be performed.

    摘要： A developing device includes a developer bearer and a stirring conveyor. The stirring conveyor includes a first conveying chamber including a conveying member and a second conveying chamber to receive the developer from an end of the first conveying chamber. The conveying member includes a forward winding blade, a reverse winding blade, and a shaft portion on which the forward winding blade and the reverse winding blade are mounted with a space therebetween. A circumferential phase of the conveying member at a start position of the reverse winding blade is different from a circumferential phase of the conveying member at an end position of the forward winding blade. The conveying member is disposed in the first conveying chamber so that the space is opposite a portion at which the second conveying chamber receives the developer from the end of the first conveying chamber.

    摘要： A development device includes a developer bearer to carry the developer to a development range, a magnetic field generator disposed inside the developer bearer for generating magnetic force, a developer regulator for adjusting an amount of the developer, a developer supply compartment disposed adjacent to the developer bearer, separated by a side wall from a portion where the developer bearer is provided, a developer agitator provided in the supply compartment, and a blocker disposed above the side wall of the supply compartment across a supply gap through which the developer moves from the supply compartment. The magnetic field generator has an attraction magnetic pole and a regulation magnetic pole. The blocker prevents the developer blocked by the developer regulator from moving along a magnetic force line of the regulation magnetic force toward the circumferential surface of the developer bearer.
