Abstract: A method for processing signals in a disk drive is provided. In the provided method, an RF signal is read at a predetermined highest reading speed, whose amplitude is adjusted with a gain. Then the level of the RF signal is adjusted by an equalizer with a predetermined parameter module. The RF signal is output if it could be read correctly. If failing to be read correctly, the amplitude of the RF signal to be read is checked. If the amplitude of the RF signal is not within a predetermined range, the gain is adjusted and then the step of reading the RF signal is re-proceeded and the procedures thereof are repeated. A further parameter module is applied by the equalizer if the amplitude of the RF signal is within the predetermined range. The procedures of the provided method are repeated after the reading speed of the disk drive is reduced if all of the parameter modules are applied.

Abstract: A method for automatically correcting an operation type of a disk drive sets a number of times of normal track seeking of the disk drive as a standard. When executing track seeking commands, the method also detects whether a number of times of track seeking in the track seeking commands is greater than the standard, judges occurrence of an abnormal track seeking phenomenon, judges a correct operation type according to an operation type setting of the disk drive and a track seeking direction, automatically corrects and switches a misjudged operation type into the correct operation type setting, and restores to the original operation type setting after the operation type is controlled and switched for a predetermined number of times so as to timely and automatically revise the misjudged operation type setting.
