In the data sheet, under the section "1. Non-IBM Formats" it says:
"Note that the Index Mark is not required by the 179X."
What does this mean exactly? How can a track contain any useful
imformation without a Index Mark?
Here is the whole paragraph for reference:
Variations in the IBM format are possible to a limited extent if the
following requirements are met: sector size must be a choice of 128,
256, 512, or 1024 bytes; gap sizes must be according to the following
table. Note that the Index Mark is not required by the 179X. The minimum
gap sizes shown are that which is required by the 179X, with PLL lock-up
time, motor speed variation, etc., adding additional bytes.
