Abstract

PURPOSE:To read and write data stably without the influence of the position and the state of tracks, by controlling a relative height of a magnetic head to a magnetic disc. CONSTITUTION:The rotation of a step motor 10 is converted to a linear motion through a driving pulley 11, a belt 13, and an inverted pulley 12, and a carriage 15 moves along a guide rail 14 through a fastening material 20 and is positioned. 1 flexible disc 3 press-fixed to a spindle 29 by a clamper 4 and a spring 5 is rotated through a pulley 8, a driving belt 9, and a pulley 6 by a driving motor 7, and an output is obtained with magnetic heads 16 and 18 pressed to the disc 3 by an arm 17 and a spring 19. The height of heads 16 and 18 is changed on inside and outside circumferences of the disc by inclining the rail 14, thereby stabilizing the output.
