<p>PURPOSE:To move a disk at a high speed by moving it in a radial direction, winding the belt of a rotation driving means round the outside circumference of the disk and bringing it into contact with the outside circumference of the disk. CONSTITUTION:When a carriage 11 is linearly moved, the disk 1 is moved in the radial direction and relative position between a reproducing head 60 and the disk 1 are changed. Simultaneously, the belt 70 of the rotation driving means formed of a driving motor 71, a driving pulley 76 and a driven pulley 72 freely fluctuated with the center of the pulley 76 as a shaft is wound round one part of the outside circumference 8 of the disk 1 and made to press-contact with it. Then, the disk 1 is turned through the belt TO and reproduced through the head 60. By such constitution that the motor 71 need not be moved together with the movement of the disk 1 in the radial direction, a disk moving type disk reproducing device which can move and access the disk 1 at a high speed is realized.</p> |
