2.3 Defect Management

2.3.1 Defect management schematic diagram

Defective sectors on the disk must be replaced with good sectors in accordance
with the defect management scheme as follows: Sectors found defective during
surface inspection are handled using a sector slipping algorithm. Sectors found
defective after initialization are replaced using a linear replacement algorithm.
Figure 2.2 shows the sector slipping and linear replacement algorithms.
