To solve the problem that in a conventional optical disk device, a printing head may interfere with a label face or label sheet of an optical disk during printing when the optical disk is thick, thereby damaging the printing head.
An optical disk device 1 is provided with: a disk drive device 9 having a disk-mounting part 20 which rotates an optical disk 2; and an optical pickup 23 which records and reproduces information signals to and from the optical disk 2; and a printing device 10 having a printing head 31 which jets ink to the printing face of the optical disk 2 to perform printing. The printing device 10 is provided with; a head-moving mechanism which moves the printing head 31 between a printing position and a retreat position; distance detection sensors 51, 52 which detect the distance between the optical disk 2 and the printing face and output the detection signals; and a distance-adjusting part which moves the printing head close to or away from the printing face, to adjust the distance.
