boundaries (User Space), and is recorded as the G List, but formatting processing is executed only for the User Space in the range specified in the “Block descriptor” and “Format parameters” (Page 3), and the “Drive parameters” (Page 4) of the MODE SELECT parameter.

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. Therefore, the defect position information specified in this command may not necessarily coincide with the defect position information read with the READ DEFECT DATA 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.
