a method for checking a disk loading status in an optical disk driver including the steps of : discriminating a loading status of an optical disk during multiple loading stages of the disk ; transmitting information to a host connected through an interface to the optical disk driver in case that disk has been jammed upon discrimination ; and performing disk - ejection operation according to a disk ejection command received from the host , wherein in the step of discriminating the loading status of an optical disk by during multiple loading stages of the disk , a loading status of an optical disk is discriminated on the basis of sensing signals respectively outputted from a plurality of optical sensor for sensing a size of the optical disk and from a loading switch for sensing whether the optical disk has been clamped .
