Spin stand having hydrodynamic bearing motor and head/disc test device
摘要：
There is provided a compact, lightweight, inexpensive head/disk test device. A spin stand is provided that supports a magnetic head to enable attaching and removal and comprises a fluid dynamic bearing motor that continues rotating even when the magnetic head is attached or removed. Alternatively, the spin stand comprises a fluid dynamic bearing motor and a detector for detecting changes in the back electromotive force or changes in the magnetic flux density generated by the rotation of the fluid dynamic bearing motor and for generating an index signal. Furthermore, the spin stand is provided with a fluid dynamic bearing motor and encloses a conductive fluid in a bearing of the fluid dynamic bearing motor and the bearing is grounded.
摘要（中）：

提供了一种紧凑，重量轻，便宜的头/盘测试装置。 提供了一种旋转架，其支撑磁头以使得能够附接和移除，并且包括即使当磁头被附接或移除时也继续旋转的流体动力轴承马达。 或者，旋转架包括流体动态轴承马达和用于检测反向电动势的变化或由流体动态轴承马达的旋转产生的磁通密度的变化并用于产生索引信号的检测器。 此外，旋转架设有流体动力轴承马达，并将导电流体包围在流体动力轴承马达的轴承中，并且轴承接地。
