ABSTRACT:
The present invention relates to a magnetic recording medium and a magnetic recording/reproducing apparatus for the same. In the magnetic recording medium there are provided a read/write region which permits modification of written data and a read-only region dedicated to the reading of data, which is used for reading only once writing is done. In recording servo information to a data format region of the magnetic recording medium, the time width of servo information in the read-only region is set shorter than that in the read/write region.
