Claims

[Claims for Utility Model Registration] A motor that rotationally drives a drive shaft that rotates a magnetic disk, and a motor that holds a magnetic head and reciprocates in the radial direction of the magnetic disk while bringing the magnetic head into contact with the magnetic disk. a head arm portion; a rotation output portion provided in the head arm portion; a rotation output portion provided in the head arm portion; a power mechanism that converts rotation of the rotational output section into reciprocating motion of the head arm section by mounting a steel belt on a support section provided on the main body case via a pulley; In the magnetic recording and reproducing device for recording and reproducing signals from the magnetic head on the magnetic disk, an end face of a pulley provided on the head arm portion;
The width of the steel belt is made larger than the gap between the end face of the pulley and the surface of the main body case located opposite to it, and the length of the pulley in the axial direction is set to a length that approximately corresponds to the width of the steel belt. A magnetic recording/reproducing device characterized by:
