A floppy disk drive is an external erasable memory equipment of personal computer. The size of floppy disk drive is smaller and smaller to 3.5 inches or 2 inches. The weight of one is fighter and lighter, and it is asked to be higher quality. The head carriage of floppy disk drive is most important part as recording information. A good recording needs to be stable contact between a head slider and the floppy disk. It is most important that a heard slider contacts the floppy disk without space. But the floppy disk drive has the space between the head slider and the floppy disk under strong vibration. To decrease the space, a new supporting mechanism of upper head carriage was developed. The normal upper head carriage is supported like a cantilever with plate spring which is weak for vibration.The newly developed supporting mechanism of head carriage reduces the degree of vibration of the head slider. The flexible heard carriage is simply supported to increase the stiffness, and the moment about the supporting point is balanced. At first it was found theoretically that the degree of vibration is reduced in the newly developed balance type more than in the cantilever one. Next the validity of the theoretical results was proven by experiment. An actual head carriage of the balance type was designed by using aluminum as material.

软盘驱动器是个人计算机的外部可擦除存储器设备。软盘驱动器的尺寸越来越小，只有3.5英寸或2英寸。其中一个重量是战斗机和更轻，它被要求更高的质量。软盘驱动器的磁头架是记录信息的重要部件.一个好的记录需要磁头滑块和软盘之间稳定的接触。最重要的是，磁头滑块与软盘的接触没有间隙。但是软盘驱动器在强烈振动下在磁头滑块和软盘之间有空间。为减小空间，研制了一种新型的上机头小车支承机构.通常的磁头滑架上部是用板簧支撑的悬臂梁，板簧的振动很弱，新开发的磁头滑架支撑机构减小了磁头滑块的振动程度。对柔性小车进行简支以增加刚度，并平衡支点力矩。首先，从理论上发现，新开发的平衡型比悬臂型振动程度降低得更多。通过实验验证了理论分析结果的正确性。以铝为材料设计了一种实际的平衡式头架。
