8.0 Defect flagging strategy
Media defects are remapped to the next available sector during the Format Process in manufacturing.
The mapping from LBA to the physical locations is calculated by an internally maintained table.
8.1 Shipped format
y
Data areas are optimally used.
y
No extra sector is wasted as a spare throughout user data areas.
y
All pushes generated by defects are absorbed by spare tracks of inner zone.

Figure 18. PList physical format
Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA
to physical is done automatically by internal table.
