ABSTRACT:
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 the disk has been jammed based upon the discrimination; and performing a 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 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.
