ABSTRACT:
A head device for a tape player has a head moving plate for bringing a head into contact with or pulling it away from a magnetic tape. The head is attached to a head holder. A forward azimuth adjusting screw and a reverse azimuth adjusting screw are adjustably screwed, in the vertical direction, through the head holder. A head driver moves the head holder up and down along the width of a magnetic tape. When the head driver is in motion, the azimuth adjusting screws are prevented from contacting a surface of the head device, thus reducing wear of the surface. Additionally, while the head driver is in motion, the head is set in a center position. When the head driver ceases motion, the azimuth adjusting screws contact a surface of the head device to adjust the azimuth and cause the head to be held at a height corresponding to the azimuth.
