Abstract

PURPOSE:To make the entire device small in size and to reduce the number of parts by supporting and fixing the near center of a guiding shaft in an axial direction and fixing the guiding shaft by adhesion. CONSTITUTION:A carriage 6 equipped with a pair of heads 4 and 5 moves in the diameter direction of a disk 1 by receiving the precession driving force of a step motor 8 fixed to a frame 3 and is positioned in an optional position according to the precession of the motor. The near center of the guiding shaft 7, which guides to move the carriage 6, in the axial direction is made to adhere and fixed to the frame 3 and the shaft 7 is engaged with bar rings 6a and 6b provided in the carriage 6 so as to freely slide in the axial direction on both sides of the adhering and fixed part. Thus, it is unnecessary to provide parts to be fixed on both end parts of the shaft 7, so that the shaft can be set in a shaft one and the entire device can be made small in size. Since the shaft 7 is made to adhere to be fixed, the number of parts can be reduced.
