3.1 Data Space Figure 3.5 Track skew/cylinder skew The number of physical sectors (track skew factor and cylinder skew factor) corresponding to the skew time varies depending on the logical data block length because the track skew and the cylinder skew are managed for individual sectors. The IDD automatically determines appropriate values for the track skew factor and the cylinder skew factor according to the specified logical data block length. The value can be read out by the MODE SENSE or MODE SENSE EXTENDED command after the track has been formatted. 3.1.4 Sector format Each sector on the track consists of an ID field, a data field, and a gap field which separates them. Figure 3.6 gives sector format examples. C141-E133-02EN 3-7

Figure 3.5
Track skew/cylinder skew
The number of physical sectors (track skew factor and cylinder skew factor) corresponding to the
skew time varies depending on the logical data block length because the track skew and the cylinder
skew are managed for individual sectors.
The IDD automatically determines appropriate values for
the track skew factor and the cylinder skew factor according to the specified logical data block
length.
The value can be read out by the MODE SENSE or MODE SENSE EXTENDED command
after the track has been formatted.
3.1.4
Sector format
Each sector on the track consists of an ID field, a data field, and a gap field which separates them.
Figure 3.6 gives sector format examples.
