    摘要： A spindle assembly for magnetic disks of both-end support type has a hub (26) for fixing the disks, a shaft (21) to which the hub is fixed, a pair of bearings (19, 28) which are spaced in vertical or horizontal direction, a pre-loading spring (27) for pre-loading one of the bearings, and a housing (15, 16) composed of housing parts which accommodates the hub (26), shaft (21), bearings (19, 28) and the pre-loading spring (27). The spindle assembly further has an axial reference surface (36) formed on the hub at a right angle with respect to the shaft (21), and another axial reference surface (35) formed on one of the housing parts (15) at a right angle with respect to the vertical portion of the bearing (28) associated with the one of the housing parts. When the shaft (21) is mounted in the one of the housing parts with the hub and the pre-loading spring (27) fitted therearound, the hub (26) is axially urged by the spring (27) such that the axial reference surface thereon (36) is brought into abutment with the axial reference surface (35) on the one of the housing parts (16). As a result, the axis of the spindle assembly is determined by the abutment between the reference surfaces (35, 36) and by the bearing in the one of the housing parts. The bearing (19) in the other of the housing parts (16) is axially aligned with the thus determined axis of the spindle assembly.

    摘要： A magnetic disk unit has a magnetic head-disk (1) stickiness eliminating mechanism suitable for a small-sized, low power consumption type magnetic disk unit of a high recording density. The magnetic disk unit has a housing (3) in which is enclosed a magnetic disk medium made of glass, a spindle and a spindle motor (2) for driving the magnetic medium in rotation, a slider (4) for supporting a magnetic head and an actuator for positioning the magnetic head. An impact force applying mechanism mounted adjacent the housing applies an impact force to the housing for manually imposing a predetermined certain impact force on the housing. By applying an impact force manually to the housing before use of the magnetic disk unit or when the disk unit becomes inoperative due to sticking, it is possible to easily eliminate the sticking phenomenon between the magnetic head and the magnetic disk medium, thus permitting operation of the magnetic disk unit.

    摘要： A data storage apparatus made up of a storage unit including at least a magnetic head (2, 19), a storage medium (1, 18), a spindle (3) and an actuator (4, 22), and a controller unit including a terminal for interface, a controller (13) for controlling the positioning of the magnetic head and the read/write operation in the storage unit, an LSI (11) for encoding and decoding a servo signal, an LSI (10) for signal processing and a circuit board, the storage unit and the controller unit being assembled within separate structures, respectively. Thus, any type of such storage unit can be combined with an arbitrary type of such controller unit in accordance with the use and purpose. Since the storage unit and the controller unit are constructed within separate structures, respectively, the data storage apparatus can be separated into the storage unit and the controller unit. Then, for example, only the storage unit having secret information previously stored can be carried, while the controller unit can be left plugged in a slot. In this case, since the structures of the storage unit and the controller unit are made thin, it is very convenient to carry them.

The spindle assembly further has an axial reference surface (36) formed on the hub at a right angle with respect to the shaft (21), and another axial reference surface (35) formed on one of the housing parts (15) at a right angle with respect to the vertical portion of the bearing (28) associated with the one of the housing parts. When the shaft (21) is mounted in the one of the housing parts with the hub and the pre-loading spring (27) fitted therearound, the hub (26) is axially urged by the spring (27) such that the axial reference surface thereon (36) is brought into abutment with the axial reference surface (35) on the one of the housing parts (16). As a result, the axis of the spindle assembly is determined by the abutment between the reference surfaces (35, 36) and by the bearing in the one of the housing parts. The bearing (19) in the other of the housing parts (16) is axially aligned with the thus determined axis of the spindle assembly.
