1. A digital versatile disc (DVD) navigator, comprising:

  • a menu panel module, configured to generate a first level in response to reception of an unload instruction;

    a quick-unload module, configured to acquire and process the first level in a sleep state of the DVD navigator to generate a second level and a pulse signal;

    wherein the quick-unload module is controlled according to the second level to quickly unload a disc in the sleep state;

    a motor module, configured to control a motor to rotate according to the second level for controlling the quick-unload module to quickly unload the disc in the sleep state;
