Abstract: An icemaker in a refrigerator is disclosed, by which heat generated from a heater to detach ice is prevented from being transferred to an inside of the refrigerator. The present invention includes an icemaker body provided to a prescribed position of the refrigerator to make to ice from a supplied water, a heater provided to the icemaker body to generate heat to facilitate detachment of the made ice, and a heater shielding unit provided to prevent the heat generated from the heater from being supplied to an inside of the refrigerator.

Abstract: A refrigerator and a method of controlling the same. The refrigerator includes: tags attached to goods stored in a storage chamber; a reader, including a plurality of antennas having different identification distances, identifying the tags using the antennas; and a control unit detecting locations of the tags attached to goods stored in the storage chamber using the different identification distances of the antennas.

Abstract: A refrigerator having improved recognition rate of RFID tags. Antennas of RFID readers are slantingly installed in walls of storage chambers, thereby increasing the recognition rate of the RFID tags attached to foods stored in the storage chambers.

Abstract: A land/groove track discriminating method and apparatus for an optical recording medium having a land/groove structure which can stably discriminate the kind of a track even in an unstable state of the system. The kind of the track is discriminated by using the differential characteristic of a tracking error signal in a header region, by using the relation that the phase of a wobbling signal in the lang track is opposite to the phase of the wobbling signal in the groove track, or by comparing phase levels of delayed first and second header region signals. Accordingly, the servo control suitable to the kind of the track can be performed at a proper time, and thus an accurate tracking control can be performed with respect to an optical disc having the land/groove track structure.
