Abstract

PURPOSE:To adjust the position of head easily with a stable output voltage, by placing the position adjustment round hole part of magnetic head upper side of the disc at the back side of screw fixing part. CONSTITUTION:The 1st magnetic head 7a which contact with the under side of a magnetic disc 1 is fixed at one edge of a carriage body 10, and a movable arm 11 on which the 2nd magnetic head 7b contacting with the upper side of the disc 1 is attached to the other edge of the carriage body so that it can turn towards the direction of arrow A through a plate spring 20 which has a head position adjusting round hole part 21. The movable arm 11 is evergized by a spring 13 to move towards the 1st head 7a. Since the position adjusting round hole part 21 of the 2nd magnetic head 7b is placed opposite side of the head 7b beyond the screw fixing part, there is no possibility that the head 7b is slanted when inserting a pin of the position adjusting jig.
