Figure 3.6 Sector format
Each sector on the track consists of the following fields:
(1) Gaps (G1)
The gap length at the time of formatting (initializing) is listed in Figure 3.6. Pattern X'00' is
written on the gap field.
(2) PLO Sync
In this field, pattern X'00' in the length in bytes listed in Figure 3.6 is written.
(3) Sync Byte (SB)
In this field, special pattern in the length in bytes listed in Figure 3.6 is written.
