Multiple zone recording
The MZR process ( Multiple Zone Recording ) increases the storage capacity of disk-shaped data carriers such as hard drives.
Conventionally, the data blocks on a disk-shaped data carrier are controlled according to track and sector . Each track is divided into an equal number of sectors .
With the MZR method, the number of sectors increases the further the corresponding track is from the axis of rotation. This results in a uniform data density and better utilization of the data carrier surface . With the MZR procedure, the individual sectors can no longer easily be addressed with traditional CHS addressing. The drive's control electronics therefore convert the existing CHS or LBA addresses into internal addresses and thus make a one-to-one assignment of the logical to the physical sectors.
