METHOD AND DEVICE FOR PREVENTING MALFUNCTION OF DISK DRIVER

摘要

PURPOSE: A method and a device for preventing malfunction of a disk driver is provided to prevent the malfunction due to the 3T correction function by selectively performing the 3T correction function depending on an operation state of the disk driver. CONSTITUTION: A DSP(Digital Signal Processor)(104) is equipped with a function to correct a 3T signal by using an RF(Radio Frequency) signal generated depending on the operation of the disc driver. A system controller(105) turns on the 3T correction function if the operation state is a stable state by monitoring the operation state of the disc driver. After turning on the 3T correction function, the system controller monitors the operation state of the disc driver and turns off the 3T correction function if the operation state is an unstable state.
