Summary:A method and apparatus for preventing a malfunction of a disc drive due to an operation error of a correction function for a minimum pit length by selectively performing the correction function based on an operative state of the disc drive. The method includes a first monitoring operation determining whether an operative state of the disc drive is stable when a disc is loaded into the disc drive, controlling a turning on of a correction function for a minimum pit length if the operative state of the disc drive is stable, and a second monitoring operation determining whether the operative state of the disc drive is stable after turning the correction function for the minimum pit length on and turning the correction function off if the operative state of the disc drive is determined to be unstable based on the second monitoring result.
