Method and apparatus for writing and inspecting servo information on disc drive

摘要

A method and an apparatus of controlling a disc drive, and more particularly, to a method and an apparatus for writing and inspecting servo information on a disc drive that minimize the effect of servo information written in adjacent cylinders caused by a gap erase field on a disc drive, write servo information on the disc drive and perform servo information inspection and defect processing, are provided. The method for writing servo information on a disc drive includes (a) centering on a cylinder having skew '0', sequentially writing servo information in a direction of the cylinder having skew '0' at an outer surface in an outer region and sequentially writing the servo information in the direction of the cylinder having skew '0' at an inner surface in an inner region, and (b) after writing of the servo information is completed, inspecting the servo information written in a cylinder at a predetermined distance from the cylinder having skew '0' and determining whether the servo information is correctly written. <IMAGE>
