(4)LBA

The logical block address is written in this field, but it is not written with MP/MC models because it is appended to BCRC field information.

(5)Data field

User data is stored in the data field of the sector. The length of the data field is equal to that of the logical data block which is specified with a parameter in the MODE SELECT command. Any even number between 512 and 528 bytes can be specified as the length.

(6)BCRC

It is a 2-byte error detection code. Errors in the ID field. Single burst errors with lengths of up to 16 bits for each logical block can be detected.

The 4-byte error detection code appended the LBA field information is used with the MC/MP models.

(7)ECC

40-byte data error detection/correction code for the data field. It is possible to on-the-fly correct the single burst errors with lengths of up to 160 bits.

(8)PAD 1

A specified length of x‘00’ pattern shown in Figure 3.6 is written in this field. This field includes the variation by rotation and circuit delay till reading/writing.

(9)PAD 2/PAD 3

A specified length of x‘00’ pattern shown in Figure 3.6 is written in this field. This field contains the processing time necessary to process next sector continuously. This field have rotational speed variation.
