に欠点があった。Generally, a magnetic disk drive device includes a magnetic disk at the tip of a carriage, and the carriage and a stepping motor are connected by means such as a steel belt, and the carriage moves in parallel along the surface of the magnetic disk. The magnetic head is positioned on a specified track on the magnetic disk.The track φφ is positioned using a photointerrupter, which is a track φφ sensor, and a light shielding plate so that the head can be accurately moved to a predetermined position. Generally, the light-shielding plate is integrally formed with the carriage and the photointerrupter is moved, but in this case, fine adjustment is difficult, and the adjustment takes a considerable amount of time, resulting in a drawback in terms of workability.
