摘要： In a magnetic disk driver for driving a magnetic disk inserted thereinto, a pair of locating members locates both ends of a guide bar to mount the guide bar on a main surface of a main frame in cooperation with a guide bar cramp. Disposed in the vicinity of a magnetic head, one of the locating members includes a projecting portion which projects on the main surface of the main frame. The projecting portion may be a projection squeezed out of the main frame by half blanking. Disposed over the main surface of the main frame and apart from the main frame, a head carriage holds a magnetic head movably along a predetermined radial direction to the magnetic disk. The head carriage comprises a head carriage body and a supporting frame for supporting the head carriage body. The supporting frame projects into the main surface of the main frame and is fitted on the guide bar. The main frame comprises a safe portion, which is opposed to the guide bar, for preventing contact of the supporting frame of the head carriage with the main surface of the main frame when the head carriage slides along the guide bar. The safe portion includes a concave portion. The concave portion may be dented by half blanking.

摘要： In a disk drive having a frame unit (63) in which a rear wall (81) is integrally formed with a bottom plate (63a) by press work such as bending, punching or the like, opening portions (53, 55, 57, 59) are inevitably formed as a designing requirement to form fixing members for fixing a circuit board or to prevent contact owing to the retreat of a carriage assembly (67) at the time of punching or press work of the rear wall (81) of the frame unit (63). To provide a disk drive having high reliability by preventing dust from entering into the disk drive from the opening portions (53, 55, 57, 59) and by preventing destruction of data on a disk owing to pressing of dust onto the disk by a recording and reproducing head, rear cover (83) is mounted on the rear wall (81) for closing the opening portions (53, 55, 57, 59).

摘要： A front shutter (13′) comprises arm portions (132, 133) formed at both ends of an upper side of a door member (131). While one shaft portion (136) is formed on one of the arm portions (132) through a positioning portion (134), the other shaft portion (137) is formed on the other of the arm portions (133). The shaft portions (136, 137′) are inserted into holes formed on a cut and raised piece (111) and a side wall (112) respectively. The cut and raised piece (111) and the side wall (112) rotatably supports the shaft portions (136, 137′). A gap between the arm portion (133) and the side wall (112) is wider because of no positioning portion between the arm portion (133) and the side wall (112). The shutter spring (14′) not only gives force to the front shutter (13′) in a closing direction but also presses the front shutter toward the cut and raised piece (111) to prevent the shutter from moving along a pivot defined by the shaft portions (136, 137′).

摘要： In a flexible disk drive for a flexible disk, a main frame defines a receiving portion for receiving the flexible disk. The main frame has a principal surface which faces the receiving portion and extends in a first direction and a second direction perpendicular to the first direction. A carriage assembly is mounted on the main frame and has a magnetic head for accessing the flexible disk. The carriage assembly is movable to carry the magnetic head along the principal surface. An eject base is coupled to the main frame and has a main portion facing the principal surface and side plates opposite to each other in the first direction. Between the main frame and the eject base, an eject plate is placed movable in the second direction for ejecting the flexible disk from the receiving portion. The eject plate has side plates facing the side plates of the eject base in the first direction, respectively. A guiding mechanism is coupled to the side plates of the eject base and to the side plates of the eject plate and guides movement of the eject plate in the second direction.
