A method of processing a disk detachment of a magnetic disk drive

摘要

end. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of processing a disk defective area in a magnetic disk drive.;I. DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention When defects due to scratches occur at the sector boundaries of the disk surface or defects occur in a straight line on the disk surface, And a method for preventing loss of data due to the presence of a sector.;All. The present invention provides a method of processing a disk defective area in a magnetic disk drive having a defective area on a medium surface by detecting a defective area on a medium surface through a defective area, If it is found that defective sectors alternately exist in the sector boundary between the cylinders, neighbor sectors of the defective sector are newly defected and newly registered in the defective sector.;la. An important application of the invention is that it can be used for disk defective processing of a magnetic disk drive such as a hard disk drive.
