4.1 Mode Parameters

•Starting Boundary

This field is enabled by the MODE SENSE command. This field indicates the beginning of the active notch or, if the active notch is zero, the beginning of the logical unit (IDD).

•Ending Boundary

This field is valid in the MODE SENSE command. This field indicates the ending of the active notch or, if the active notch is zero, the ending of the logical unit (IDD).

•Page Notch

This is a bit map which shows whether or not other mode pages are being changed if the device is notched. The most significant bit of this field corresponds to page code 3Fh and the least significant bit corresponds to page code 00h. If it is specified, the IDD disregards this value.
