(2)PLO Sync

In this field, pattern X'00' in the length in bytes listed in Figure 3.6 is written.

(3)Trailing (TRNG)/Sync Byte (SB)

In this field, special pattern in the length in bytes listed in Figure 3.6 is written.

(4)LBA

The logical block address is written in this field.

(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 to 528 bytes can be specified as the length.

(6)BCRC

It is a 4-byte error detection code. Errors in the ID field. Single burst errors with lengths of up to 32 bits for each logical block can be detected.

(7)ECC

24-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 89 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.
