Rotational driving apparatus for disk and manufacturing method therefor |
摘要 |
The rotational balance by weight of a rotational driving apparatus for a disk is adjusted in a state in which a hub or a dummy member equivalent to the hub is fixed onto a turntable while a motor thereof is driven. When the hub is mounted on the turntable, rotation with excellent weight balance can be achieved, resulting in prevention of vibration due to imbalance of weight.
