Claims

[Claims for Utility Model Registration] In a magnetic disk device, a guide is provided so as to be offset from the rotating shaft of a spindle motor that drives a magnetic disk, and a carriage on which a magnetic head is mounted is movably provided along the guide. , the guide includes two first guides each having a circular cross-sectional shape;
The carriage is configured with a second shaft, and these shafts are arranged parallel to each other at different heights, and the carriage rotates about a horizontal axis so that the stop surface of the outer race is rotated about the horizontal axis. A first bearing that slides on the first shaft, and a second bearing that rotates around a horizontal axis so that the lower surface of its outer race slides on the second shaft, totaling three or more. a third shaft rotatable about a vertical axis such that an outer race outer surface thereof slides on one side of the first shaft;
and a fourth bearing that rotates around a vertical axis so that its outer race outer surface slides on the other side of the second shaft, and A magnetic disk device characterized in that the carriage is provided with biasing means for applying a load in the radial direction of the bearing.
