    • A magnetic disk apparatus includes a spindle motor for rotating a magnetic disk. Either a first pulse-train signal or a second pulse-train signal is selectively generated. The first and second pulse-train signals are different from each other in pulse frequency. When the first pulse-train signal is generated, the spindle motor is controlled to rotate at a first rotational speed in response to the first pulse-train signal. When the second pulse-train signal is generated, the spindle motor is controlled to rotate at a second rotational speed in response to the second pulse-train signal. The second rotational speed differs from the first rotational speed.
    • 磁盘装置包括用于旋转磁盘的主轴电动机。 选择性地产生第一脉冲串信号或第二脉冲串信号。 第一和第二脉冲串信号在脉冲频率上彼此不同。 当产生第一脉冲串信号时,响应于第一脉冲串信号,主轴电机被控制为以第一转速旋转。 当产生第二脉冲串信号时,响应于第二脉冲串信号,主轴电机被控制为以第二转速旋转。 第二转速与第一转速不同。

    • A threading mechanism for a magnetic tape machine is contrived so as to obtain sufficient driving power when the threading arm is latched with a leader block at a position where the leader block is stopped in a cartridge or a machine reel, and is also contrived so as to avoid impact force based on a driving motor even when the threading arm stops suddenly at the stop position. The positions where the leader block is stopped in the cartridge and the machine reel are inside a track of the threading arm which swings around its pivoting point and the leader block is threaded therebetween. A driving arm for swinging the threading arm is motor-driven around a pivoting point of the driving arm itself. The driving arm causes the threading arm to work together between the positions where the leader block is stopped, and cancels the working with the threading arm in the direction of the trace over the disengaging positions, so as to be swung.
    • 设计一种磁带机的穿线机构,以便在引导块在引导块停止在卡盘或机器卷轴中的位置处用引导块锁定时获得足够的驱动力,并且还被设计为 以便即使当牵引臂在停止位置突然停止时也避免基于驱动电动机的冲击力。 引导块在卡盘和机器卷轴中停止的位置在螺纹臂的轨道内,该螺纹臂围绕其枢转点摆动,并且引导块在其间螺纹连接。 用于摆动穿线臂的驱动臂围绕驱动臂本身的枢转点进行电机驱动。 驱动臂使穿线臂在引导块被停止的位置之间一起工作,并且在穿过分离位置的迹线方向取消与穿线臂的工作以便摆动。
