• Sector access mode: Performs a read or write in sector units by specifying a sector and controls
(4)
• A sector is the basic unit of access and comprised of 512-byte data and 16-byte control code.
• The position of the ECC in the control code can be specified in 4-byte units.
• User information can be written to the control code other than the ECC.
(5)
• 8-byte ECC code is generated and error check is performed for a sector (512-byte data + 16-
