Note Spare sectors on the last track in each cylinder are not necessarily placed at the end of the track
because of a track skew or a cylinder skew. (Details are explained in Subsection 3.1.3.)
Apart from the above logical configuration, the IDD intends to increase the storage capacity by
dividing all cylinders into several zones and changing a recording density of each zone. Tables 3.1 to
3.3 show the zone layout and the track capacity.
