There is provided an optical disk apparatus that can inhibit, during recording or reproduction of data on or from an optical disk, a side runout that may occur in the optical disk in its circumferential direction as a result of Coriolis force when a disk rotating shift is subjected to procession movement, thereby allowing recording and reproducing quality to be stabilized and a reduced size of the apparatus. The disk apparatus provided has pressure pawls arranged at intervals smaller than those in the prior art, each of which is provided with a plurality of pressing points arranged at intervals larger than those in the prior art. Particularly, an interval between the pressure pawls is an acute angle in terms of the center angle of the disk. An interval between the pressing points is an angle of 35° or larger.
