Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device that allows high-speed access to other layers in a hybrid optical disk, and a speed determination method. SOLUTION: The optical disk device 100 includes: a light source 106; a light source control means 108; a condensing means 110; a light receiving means 112; a signal processing means 114; a servo means 116; a disk discrimination means 118; and a speed determination means 124. In a hybrid optical disk including reproduction-only layers and recordable layers, the optical disk device 100 eliminates the need to change the number of revolutions by reproducing information from the reproduction-only layer and the recordable layer at the same speed, thereby optimizing the access time to the other layers.

Abstract: PROBLEM TO BE SOLVED: To provide a technology which discriminates a defect on an optical disk from disturbance applied to an optical disk device, detects only defects, and stably controls the position of a light spot when the optical spot passes through the defect. SOLUTION: Circumference of an optical disk 101 is divided into a plurality of circumferential sections by a circumferential section dividing signal generating means 110, a defect correcting means 111 decides whether a defect exists for each circumferential section, a control means 150 holds position control of the light spot in a circumferential section having a defect.
