Because each sector still contains the same number of bytes, the outer sectors have lower bit density than the inner ones, which is an inefficient use of the magnetic surface. The solution is zone bit recording, wherein the disk is divided into zones, each encompassing a small number of contiguous tracks.
Because each sector maintains an equal quantity of bytes, outer sectors have lower bit density than inner ones, which is inefficient use of the magnetic surface. The resolution involves dividing the disk into zones, where each zone includes a small set of contiguous tracks.
