    • When a reproduced signal is outputted from the MR head to the envelope detector, the positive envelope joining positive peaks and the negative envelope joining negative peaks are outputted from the envelope detector to the asymmetry detector. An asymmetry value or fluctuation value of the reproduced signal waveform can be found through comparison of the positive envelope and negative envelope and calculation at the asymmetry detector. If these values do not fall within a desired or permissible range, a high degree of asymmetry is indicated in the reproduced signal waveform, and the sense current controller accordingly alters the sense current value. This operation is continued until the envelope of the reproduced signal waveform resulting from the new sense current falls within the desired or permissible range.
    • 当将再现信号从MR头输出到包络检测器时,将正峰值和负包络线连接负峰值的正信号从包络检测器输出到不对称检测器。 可以通过比较不对称检测器的正包络和负包络以及计算来找到再现信号波形的不对称值或波动值。 如果这些值不在期望的或允许的范围内,则在再现信号波形中指示高程度的不对称性,并且感测电流控制器相应地改变感测电流值。 该操作继续进行,直到由新感测电流产生的再现信号波形的包络落入所需或允许的范围内。

    • Apparatus for positioning and attaching a reinforcing ring in coaxial relationship to a floppy disk, includes a force translating mechanism mounted for movement to and from a resiliently mounted circular receiving member. A cylindrical positioning member, connected to the force translating mechanism, has first and second concentric reference surfaces corresponding respectively to the inner diameter of the reinforcing ring, which is carried by the force translating member, and the inner diameter of the floppy disk, which is disposed about the receiving member. During movement of the force translating mechanism toward the receiving member to bring the reinforcing ring into bonding relationship with the floppy disk, the positioning member moves axially relative to the force translating mechanism between (1) a first position in which the first reference surface causes the force translating mechanism to carry the ring in a predetermined disk-attaching position, to (2) a second position engaging the receiving member in which the second reference surface causes the floppy disk to be located in a position concentric with the disk-attaching position of the ring.
