    摘要： There is provided a region at a corner of a head disk assembly (17) which region includes a recess, a hole or a threaded hole (1a) into which a connection member for fixing a magnetic disk drive is to be inserted inside the drive through a surface thereof from the exterior. With this construction, the mounting of the drive can be effected with a sufficient strength. Moreover, various mounting requirements can be satisfied while maintaining the same performance as conventionally obtained, and also achieving a compact and thin design, a power-saving design and a low-cost design of the drive.

    摘要： The present invention is intended to provide a compact, energy-saving, quick-access magnetic disk unit having a reduced thickness. A coil holder (3a) for holding a driving coil (1) for moving a carriage (3) supporting a magnetic head (4) is fitted in a space surrounded by the driving coil (1). The driving coil (1) has a portion, which moves in a space between opposite permanent magnets (2a, 2b), having a thickness smaller than the other portions of the driving coil (1).
