Claims

[Scope of utility model registration request]

The engaging element of the carriage carrying the head is engaged with the spiral groove of the screw shaft, and the screw shaft is rotated by the driving force of the stepping motor, thereby linearly feeding the carriage by a predetermined amount, and In a disk recording and reproducing device that positions a head on a disk that rotates around the screw shaft, a bearing rod that comes into contact with the tip of the screw shaft is provided, and the engagement element and the spiral groove are connected from the tip of the bearing rod. a distance in the axial direction of the screw shaft to the engaging portion;
The distances from the center of the spindle to the head are approximately equal, an adjustment screw is provided on the chassis that supports the spindle, and the tip of the bearing rod is brought into contact with the conical end of the adjustment screw,
1. A magnetic disk recording and reproducing device, characterized in that the screw shaft can be moved in an axial direction against a spring force within the stepping motor by rotating an adjusting screw.
