DETECTION OF AZIMUTH ANGLE OF MAGNETIC HEAD, MEDIUM FOR DETECTING AZIMUTH ANGLE, AZIMUTH ANGLE DETECTOR AND AZIMUTH ANGLE ADJUSTER

PURPOSE:To exactly perform an operation to adjust the azimuth angle of a magnetic head without receiving the influence of a tape speed, etc. CONSTITUTION:Two tracks 15, 16 for azimuth angle detection signals and a reference clock recording track 17 are formed on the recording surface of a test tape 5. The tracks 15, 16 for azimuth angle detection signals are provided with magnetization transition points 21, 31 on the perpendicular line of the tape traveling reference plane 5a of the test tape 5. The reference clock recording track 17 is provided with magnetization transition points 41 to 44, 41' to 44' at the pitch sufficiently smaller than the pitch for forming these magnetization transition points 21, 31. The number of the read signals of the magnetization transition points 41 to 44 between the read signal of the magnetization transition point 21 and the read signal of the magnetization transition point 31 is counted in the read signals of the magnetic head and the azimuth transition angle theta of the magnetic head is determined from the results of the counting.
