    • Embodiments of the invention provide a magnetic disk drive whose flexibility in the layout of components is enhanced in spite of the fact that a magnetic disk and a driving section such as the voice coil motor that drives a head arm are isolated from each other. In one embodiment, a magnetic disk drive includes a magnetic disk compartment in which a magnetic disk, a head that reads/writes data from/onto the magnetic disk, and a head arm holding the head are disposed, and a VCM compartment with an internally disposed VCM that pivotally moves the head arm about a pivot shaft. The magnetic disk compartment and the VCM compartment are separated by an isolation wall provided at the bottom of the magnetic disk compartment along the recording surface of the magnetic disk. The pivot shaft is disposed in a penetrating form in an opening.
    • 本发明的实施例提供一种磁盘驱动器,尽管磁盘和诸如驱动头臂的音圈电动机的驱动部分彼此隔离,事实上增强了部件布局的灵活性。 在一个实施例中,磁盘驱动器包括一个磁盘室,磁盘盒中设置有一个磁盘,一个从磁盘读取/写入数据的磁头和一个保持磁头的磁头臂, 设置有使头臂围绕枢转轴枢转运动的VCM。 磁盘室和VCM隔室由沿着磁盘的记录表面设置在磁盘室底部的隔离壁分开。 枢轴以穿透的形式设置在开口中。
