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.
