Abstract: The object is to improve the read error rate for identification (ID) information In a sector servo type magnetic disk drive with a head comprising separate read and write elements. A pair of ID fields 21a and 21b are set up in each sector In each track of a magnetic disk for recording ID Information. The pair of ID fields are separated from each other along the track and radially displaced with respect to each other by a distance equal to an offset between the read element 24 and the write element 23 associated with the track. In a data write operation for a trace the magnetic head is positioned so as to read the ID information in the ID field 21b with the read element 23. In a read operation for the track, the head is positioned so as to read the ID information in the ID field 21a with the read element 23.
