A method of controlling a tracking error balance in an optical disc apparatus, and the optical disc apparatus are discussed. In an embodiment of the present invention, when a tracking error balance for writing is controlled, a beam power that is appropriate for the writing characteristics of an optical disc is applied. The beam power can be determined based on the Manufacturer Identifier (MID) of the optical disc and writing power information for different MIDs. The beam power can be determined to be a value of 20 to 50% of the prestored writing power for the MID of the optical disc.

A method of forming a polycrystalline silicon layer and an atomic layer deposition apparatus used for the same. The method includes forming an amorphous silicon layer on a substrate, exposing the substrate having the amorphous silicon layer to a hydrophilic or hydrophobic gas atmosphere, placing a mask having at least one open and at least one closed portion over the amorphous silicon layer, irradiating UV light toward the amorphous silicon layer and the mask using a UV lamp, depositing a crystallization-inducing metal on the amorphous silicon layer, and annealing the substrate to crystallize the amorphous silicon layer into a polycrystalline silicon layer. This method and apparatus provide for controlling the seed position and grain size in the formation of a polycrystalline silicon layer.

A method for inter-processor communication in a mobile terminal is disclosed. The method of inter-processor communication for a mobile terminal having a first processor, a second processor, and a shared memory includes determining, by the first processor, the size of data to be sent to the second processor, comparing the determined size of the data with the size of one of multiple buffer areas in the shared memory to be used for transmission, rearranging the shared memory according to the data size when the size of the data is greater than the size of the buffer area to be used, and sending the data to the second processor through the rearranged shared memory. It is possible to increase data transfer rates between processors when inter-processor communication is performed through a shared memory in a mobile terminal having multiple processors.
