    • A disk driver in which a disk is inserted has a head (12), a holder (5), and a slider (14). The holder ascends and descends between a first position and a second position. The head ascends and descends between a third position and a fourth position in response to the ascending and descending of the holder. The disk (3) is inserted into or ejected from the holder (5) at the first position when the head (12) is at the third position, and information is recorded on or reproduced therefrom by the head at the fourth position when the holder is at the second position. Since the third position is higher than the first position so that the head does not hit the inserted disk, there is a space between the first and third positions. Accordingly, the slider (14) is located in the space so that it can avoid hitting the head, and thus the disk driver can be made thin.
    • 其中插入盘的盘驱动器具有头(12),保持器(5)和滑块(14)。 保持器在第一位置和第二位置之间上升和下降。 响应于保持器的上升和下降,头部在第三位置和第四位置之间上升和下降。 当头部(12)处于第三位置时,盘(3)在第一位置处插入或从保持器(5)弹出,并且当保持器 处于第二位。 由于第三位置高于第一位置,使得头部不撞击插入的盘,所以在第一和第三位置之间存在空间。 因此,滑块(14)位于空间中,从而可以避免撞击头部,从而可以使盘驱动器变薄。

    • A flexible magnetic disk drive is disclosed which has a stepper motor coupled to a data transducer via a steel belt motion translating mechanism for moving the transducer from track to track on the rotating disk in response to stepping pulses and a stepping direction signal from an external host system. In order to save power, the stepper motor is held deenergized while the disk drive motor is out of rotation, with the consequent possibility that the transducer may be displaced from the required track position on the disk while the stepper motor is held deenergized. Therefore, in order to always memorize the latest of the successive destination tracks commanded by the host system, a forward/backward counter is provided which counts the external stepping pulses in either direction depending upon the binary state of the external stepping direction signal. After the disk drive motor is set into rotation, stepping pulses and an stepping direction signal are generated internally for causing the stepper motor to automatically reposition the transducer on the memorized latest destination track.
    • 公开了一种柔性磁盘驱动器,其具有经由钢带运动转换机构耦合到数据传感器的步进电机,用于响应于步进脉冲和来自外部主机的步进方向信号将转换器从轨道移动到旋转盘上 系统。 为了节省电力,步进电动机在磁盘驱动电动机不能旋转的同时保持断电,从而随着步进电动机被断电而使换能器从盘上所需轨道位置移位的可能性。 因此,为了始终存储由主机系统指令的连续的目的地轨迹的最新,提供了前向/后向计数器,其根据外部步进方向信号的二进制状态对任一方向的外部步进脉冲进行计数。 在磁盘驱动电动机转动之后,内部产生步进脉冲和步进方向信号,使步进电动机自动地将换能器重新定位在存储的最新目的地轨道上。
