  • Patent number: 7269108
    Abstract: A disc drive, and method of automatically ejecting a disc from a disc player. The method comprises selecting a main title from a plurality of titles recorded on the disc and storing a playback time of the main title in a memory, and determining whether the main title is playing, or has played, back.
