3. If a defect descriptor in the "Byte distance from the Index format" is specified in the D List,
depending on the byte position of the specified defective byte, 1 sector may be processed as a
defective sector with 2 or more defect descriptors. Also, if the specified defective byte position
has no influence on data block read/write operations, that defect position information is
disregarded and is not the object of defective sector processing, and thus is not recorded in the
G List.

command after this command is terminated.
(4) Defect processing during initialization
Table 3.5 shows each combination of control flag specification values and the contents of processing
executed by the IDD. Furthermore, see Chapter 3 "Data Format" of the "Product Manual" concerning
alternate block allocation processing methods.
