Abstract

A driving apparatus for optic disk include the following features. The 1st optic disk with 1st recording density of selective carrying data. The disk rotation-operating device for the 2nd optic disk with a 2nd recording density, which is higher than the recording density of 1st optic disk. The optical signal-picker for focusing the light beam emitted by light source to illuminate the article lens on 1st or 2nd optic disk. The determination device for determining the type of optic disk carried on disk rotating device. The bias-controlling device for controlling the relating inclination between article lens and optic disk carried on disk rotating device. The bias control-stopping device for stopping the bias control proceeded by bias control device when the determination device is inspecting the 1st optic disk.
