An optical disk drive has a lid an emergency ejection hole. An opening is defined in the lid. The emergency ejection structure comprises a locking element having a locking hook and an ejection lever, a safety element movably disposed under the emergency ejection hole, and an electromagnetic unit for generating magnetic field to attract the safety element in the optical disk drive. The locking hook is fitted the opening and keep the lid closed. With magnetic force, electromagnetic unit attracts the safety element. The locking hook can engage with the opening when the optical disk drive is connected to electrical power that enables the electromagnetic unit to attract and hold the safety element. The locking hook can disengage from the opening when the optical disk drive is disconnected from electrical power, enabling the electromagnetic unit to release the safety element.
