    • A method of writing information on a magnetic disk having a multiplicity of concentric recording tracks on a recording surface thereof, each track having sectors each of which includes a sector-identification field, and a data field on which the information is written. Initially, a magnetic head is positioned at a first erase position away from a centerline of selected one of the tracks by a predetermined distance in one of radially inward and outward directions of the disk. After reading the sector-identification field of selected one of the sectors of the selected track, the magnetic head is activated to perform a first erasing operation on the data field of the selected sector. Then, the head is moved to a second erase position away from the centerline by a predetermined distance in the other radial direction, and is activated to perform a second erasing operation on the same data field, after the sector-identification field has been raised. The head is then moved to the centerline of the selected track, and activated to write the information on the erased data field, after the sector-identification field has been read.
