HDD Zoned Bit Recording

The more remoteness from the magnetic disk centre is, the more the length of tracks increases that allows recording more information (sectors) on them at a constant speed of the spindle motor rotation, preserving constant density of recording on the entire magnetic disk surface thus allowing to use the capacity of plate magnetic surface more efficiently without any decrease of the stored data reliability. This technology was given the name zoned bit recording. It is used together with other techniques of a magnetic recording for record density increase.
