摘要： An embodiment of a magnetic disk apparatus in accordance with the present invention includes a magnetic recording medium, a magnetic head assembly having a magnetic head which reads and writes data on the magnetic recording medium, and a motor coil assembly rotationally driving a spindle motor rotation body, in which plural motor coils are arranged on a circumference around the rotation center of the spindle motor rotation body so that intervals in the circumferential direction are equal, in a stator base surrounding a periphery of the spindle motor rotation body and having a shape in which a prescribed moving locus portion of at least the magnetic head assembly is cut out.

摘要： Embodiments of the present invention provide a magnetic disk unit capable of attaining miniaturization, lower cost, lighter weight, lower profile, and higher density. According to one embodiment, only a carriage and a spindle motor among respective constituent components of a hard disk drive (HDD) are securely attached to a support plate made of a hard metal material higher in rigidity than a shroud. All the constituent components of the HDD, except the carriage, and the spindle motor, (a voice coil motor, a ramp, a latch lever, an HDD connector and so forth), that is, the respective constituent components of the HDD, of which assembling precision, rigidity, and so forth are not required, are attached to the shroud small in wall-thickness, and lighter in weight, formed of a resin material such as plastics and so forth.
摘要翻译：本发明的实施例提供了能够实现小型化，低成本，重量更轻，更低轮廓和更高密度的磁盘单元。根据一个实施例，只有硬盘驱动器（HDD）的各个组成部件中的托架和主轴电动机牢固地附接到由刚性高于护罩的硬质金属材料制成的支撑板上。除滑架外的HDD的所有构成部件，以及主轴电动机（音圈电动机，斜坡，闩锁杆，HDD连接器等），即HDD的各个构成部件，不需要组装精度，刚性等，而是由诸如塑料等的树脂材料形成的壁厚小，重量更轻的护罩上。
