Note:
Banding as defined here refers to the number of spare sectors provided per cylinder to reallocate
defective sectors. Band 2 cylinders are those nearer the inside diameter of the data surfaces.
These have additional spare sectors since the likelihood of defective sectors is higher in this
region. This feature does not affect the instantaneous media data rate which is constant across all
cylinders.
