Abstract

PURPOSE:To obtain a small magnetic disk device by positioning a motor interlocked to a carriage through a straight line operation mechanism by a rotary shaft so that the rotary shaft may extend in the orthogonal direction with the magnetic disk surface. CONSTITUTION:A motor 40 is fitted so that a rotary shaft 40a can be in the orthogonal direction with a plane of a magnetic disk 1 and fitted so that a part can be overlapped to a disk 1. A rotting force of the rotary shaft 40a is converted by a steel band 5 as a force of the straight line direction, a carriage 2 is shifted in the radius direction of the disk 1 and a magnetic head 6 is shifted. An outer diameter of the motor becomes a depth direction of a magnetic a magnetic head device, thickness of the device is not influenced by the outer diameter, composed of thickness of the motor 40, length of the rotary shaft 40a and space necessary to load the disk, and therefore, becomes thin. The motor 40 can be fitted to a lower part than the disk 1 and depth dimensions of the device can be made small. Consequently, the magnetic head device can be made smaller.
