    摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head for writing data into and reading data from the magnetic disk, a carriage pivoted on a pivot bearing while holding the magnetic head at its one end, the pivot bearing being constituted by a cylindrical sleeve serving as a fixed axle, bearing units each having an outer race fitted to the inside of the sleeve, bearing balls, and an inner race, and a shaft having the outside fitted to the inner races of the bearing units, thus, change of a pre-load caused by a heat expansion difference between the shaft and sleeve is an axial direction is compensated with a change of a pre-load caused thereby the same is a radius direction. Hence, the weight of a pivotally movable portion of an actuator is reduced.

    摘要： According to the invention, there is provided a carriage arm assembly including a carriage arm having two arm members. The arm member is constructed in such a way that the width of its coil side end and the width of its suspension side end are narrower than that of its intermediate area. This construction widens a servo band width, improves positioning accuracy, and reduces positioning errors of a magnetic disk apparatus, so that recording density is improved and storage capacity is increased. Further, by coupling two arm members using a restriction member via a visco-elastic member, it is possible to achieve a high damping effect on various vibration modes including in-plane bending of the arms, and suppress vibration of the carriage so as to reduce the positioning errors.

    摘要： A carriage arm assembly for swingably supporting a magnetic head which includes a slider, a suspension carrying the slider, a carriage arm to which the suspension is attached, and a body section. The carriage arm extends from the body section and includes first and second arm members extending substantially in parallel with a swinging plane of the carriage arm, and a fixing portion provided at a distal end of the carriage arm for mounting the suspension thereon. Each of the first and second arm members have narrow sections in a distal end area and a base end area thereof, wherein a width of the narrow sections in a swinging direction is smaller than a width of an intermediate area of the first and second arm members.

    摘要： A magnetic disk drive comprises at least one magnetic head for reading and writing information on at least one magnetic disk, a carriage supporting the magnetic head over the magnetic disk for movement of the magnetic head about a predetermined shaft, an annular coil supported by a bobbin provided on the carriage and subjected to an electromagnetic force for driving the carriage. The drive further comprises a first connection member for joining the annular coil and the bobbin, an in-coil member arranged inside the annular coil, and a second connection member for joining the in-coil member and the annular coil. A modulus of longitudinal elasticity of the in-coil member is larger than that of the first or second connection member. The drive thus formed has the increased carriage rigidity, the improved positioning accuracy of a magnetic head and the increased recording capacity of the disk.
